Thanks a bunch for that awesome demonstration on Bird Mouth joinery Dave. I watched it over and over to get as much information as possible! Thanks, AmosP
Excellent walkthrough it’s like being back in my middle school shop class
Thank you for taking the trouble to provide a very helpful, informative, and clearly explained set of videos. You've saved me a lot of trial end error, and certainly helped me get off to a very successful start with birds-mouth router joinery.
It's a mystery to me why anyone would be rude enough to give these videos the thumbs-down!
Thanks, Pete! As you get into the joinery, and have questions, don't hesitate to ask. Have fun!
Wow! One of the most well thought out and detailed woodworking videos I've ever watched. I appreciate the off-camera prep work that went into demonstrating your points.
Kind words, Dean! Thanks! I hope that you are moved to give bird mouth joinery a try!
Wow, what a marvelous video. You're a terrific teacher. I was delighted to discover that the sides don't have to be identical in width. The picture of your planter at the end of the video spoke volumes. Thank you thank you.
Excellent! Thanks very much Dave for the excellent information. A credit to CZcams.
Hi David, you are an absolute genius!!! I look forward to incorporating your teaching into my future woodworking projects.....Kev
A great demonstration video. I love the way you have added the additional 'filler' to get that wonderful effect on the three examples of your work. Thank you again.
Thanks, Malcolm! Glad that you enjoyed the video!
David
Thanks for introducing me to BMJ. After stumbling across your videos I was quite impressed with your work and what theses bits could do. I received my bits the other day and have enjoyed the time I've spent trying to set them up.
Thanks for the videos and please make some more.
Hi Dave! I'm very glad you found my videos inspiring enough to buy the bits; I hope all is going well with them. Thanks for the comments!
Outstanding presentation, excellent in every way!
Thanks for the effort you put into this.
GaslightAlley Many thanks for your kind comments and for watching my video!
Thanks for taking the time and I will look at the rest of your projects and techniques as I want to do an outdoor planter - as it will be outdoor with a large plant in humid Miami I will probably add copper banding or wire banding to hold it together -
I really appreciate the time you took to make these videos. I learned a lot.
Thanks, Duke! I enjoy making them.
awesome explanation!! thank you for being so clear and practical in your video!!
The examples at the 10:00 minute mark was an excellent idea thank you very much
Thank you Dave for the great demo! Ive never heard of that bit before. well done.
+Jeremy Grefe Thanks, Jeremy! I hope that you give bird mouth joinery a try!
Very informative video David. Your presentation and explanations are easy to follow.
Thanks, Shayne!
Great tutorial for an indepth knowledge of purpose and usage of a bird mouth router bit. Thanks for sharing such crisp narrative.
Thank you for your very kind comments, Bakthavathsal! I hope that you give bird mouth joinery a try!
sure Sir, I have already ordered the router bit and once i get them, would start taking few baby steps, using them safely.
Thankyou David for a very well explained video . I now know were i was going wrong with my cuts i was going to deep all the time but thanks to you now' i am on the righr path. Best of Irish luck from Dublin
ANOTHER WHO REALLY UNDERSTAND THE LESSON OF TECHNICAL AND ARTS, I LIKED. FROM BRASIL.
Obrigado, Severino!
Just bought some of these bits - wanted to re-learn about them and found this video. The best part is; - this is the video that taught me about them in the first place. Thanks for posting such a wonderful video.
+Shogun-Jimi Many thanks for your thoughtful comment! I'm delighted to find that this introductory video is getting increased traffic over the last year or two.
Hi David , Very explicit and gave me a lot of useful information Thanks
Abmyboy Smith Thanks Abmyboy! Glad you found it useful.
Thank you for showing us how to set up bird mouth router bits. And for showing this what it looks like if you don't set them up correctly. Which as you say, can lead to interesting looking results. I also appreciate that you showed some of your finished work. I'm curious as to how you got the inlay in the joints on the lamp. I have some ideas but I'm wondering if you have a video that shows that? Or some simple explanation. Thank you!
I hope you keep this up .I started to watch you videos a few years was very interested ,got the bit from Lee Valley
got sick and was out of it for a few years. Back at it and learning all over again with your help it should not take
me long. I have been woodworking for many years ,building furniture ,cabinets ,carving, making picture frame, building
house . I have to say i am very interested ,i make peer mugs and i think bird mouth joinery will be a big help.
Thanks again . Julien Lamarche
Hi Julien! Glad to hear that you are back into woodworking! I understand what you are saying about health problems getting in the way. I hope BMJ has been helping with your beer mug projects. And thanks for looking at my videos; any feedback is welcome!
Oh of course. No rush. I really appreciate it. It will be a beautiful addition to our patio.
Excelent explanation! Thanks for sharing!
Very nice presentation, well done, thanks, Dave
Thank you, Dave!
Thanks for this great video - it's one of the best woodworking presentations on CZcams. I hope you continue to make more such videos.
One thing came to my mind watching this... With a tilting router lift, you could use only one router bit to cut both six and eight sided joints, as well as any other polygon (five sided, seven sided, etc...). Matthias Wandel (a woodworker from Canada) designed one of these tilting router lifts.
Look up on CZcams: "titling router lift" for more information.
This is THE lesson! Thanks.
Fantastic video! Thanks
Great video! Thank you.
You sound just like Dallin H. Oaks. It’s worth listening to him on CZcams.
I totally agree, thank you, I have been attempting to make my own snare drums and getting very frustrated, this seems as if it will finally work.
Very well explained, good job. Perfect
Thanks for your generous comments and for viewing my video, Zbigniew!
thank you so much. am looking forward to trying this. Your pieces are beautiful, btw.
+Marj Frank Thanks, Marj! I think you'll find that bird mouth joinery is a lot of fun!
Thanks! Sorry I missed your post earlier. I don't do an exact calculation, but do use two ways to get close. Mostly, I sketch the cross section of the piece on 1/4" crossruled graph paper at 1:4 scale, and take measurements from that. Or, for regular shapes (all sides equal) I assume the hexagon or octagon cross section is about the same as a circle, figure the diameter (pi x dia), and divide by 6 or 8 to get stave width. For a 24" planter, pi x 24" is 75". Divide 75 by 6 or 8 = 12.5" or 9.4".
Excelente Mr. David, es usted un amor, gracias por las clases
Gracias, Lorena!
@@davidhenry32 😀😊
All CZcams videos should have explanations this clear. I sat next to you at the last SDFWW meeting and was impressed with your samples. I'm going to buy a bit and try it. I'll let you know how it works.
Thanks very much, Charles! I appreciate both the comment and the fact that you were moved to give BMJ a try! If you have any questions please contact me. I'm sure that you'll have fun with the bit. I hope to see you at upcoming SDFWA meetings!
very well explained, good job. Bob
Thanks, Bob! I really appreciate your comments!
David ,
Just stumbled on this today via The Drunken Woodworker site.
Excellent video. All new to me.
Thank you for taking the time and sharing.
JimE
JimE - many thanks for your comments! Sorry to be so long in responding. Glad you enjoyed the video.
Very timely David.
I am currently working on what I call "Useless wooden Christmas gifts" for friends and family. I just finished cutting all of the pieces for 22 napkin holders from you design. So far I have got about five hours in getting the pieces from very rough lumber to sized pieces. That includes 1.5 hours cleaning my Oneida Super Gorilla. Didn't notice the bin was full and continued putting chips and dust into the filter. Really dumb, because I have done it before and I have a warning system on it(if I turn it on).
I had made some setup blocks from the first napkin holder I did, so bit stetup was just a matter of tweaking.
Hope you will consider more videos soon.
Back to the shop. The job for sanding, routing, more sanding, assembly, bandsaing, more sanding and finishing.
Thanks again for the ideas.

blackemmons
JimE - sounds like you have really bought into BMJ in a big way. Hope all proceeds smoothly, now that the shavings bin is clean!
Coincidentally, I have just finished a video detailing napkin holder construction, and should post it today or tomorrow. Considering the size of your effort, you may be the reigning world's expert on BMJ napkin holders, and don't need any more help! My guess is that recipients of your napkin holders will find them very useful; they sold quite well at a craft fair a couple of years ago in which I was a vendor.
Dave
wow, very nice informative video, great work
Thanks Dave. I got my bit from Lee Valley. I may get a Yonico 8 sided bit from Amazon (at nearly half the price) I will do some more testing with the numbers you suggest.
Hey, Samson! - Thanks for your interest. No formal plans but if you can wait a few days more I will send a detailed sketch via your website. OK?
Very good instructional video, keep it up.
Steven Cofer Thanks, Steven! That's my plan!
Great video - thank you!!
Thanks for your kind comment,Larry!
Very good video
sweet good info.
wow, its new way that i did not know.
Thanks, Matescium! Give it a try; it's worth the effort!
Great video thanks!
Kind words, indeed! Thanks paulusandronicus!
The bird mouth bit is sometimes used to construct a hollow mast for a sailboat. The taper is incorporated after the bird mouth cut by trimming the square edge. The little bit protruding at the joint is removed when the mast is planed from 8 sides to 16. Depending on the diameter the remaining edges may be planed again to form 32 sides. Sanding and scraping will round off the corners to the final shape.
I will be trying this as soon as my bits arrive. I have some ideas to incorporate this in my game calls
Very interesting! Great idea; I look forward to seeing what you come up with!
davidhenry32 I know I can make a slate type turkey call but want to experiment to make a turned Call like a duck call maybe.
Dear Friend, im so excited with your teaching about woodworking, small pieces , and im earning money with this, i have made vases and buckets for flowers orchid, and have good aceptance , here in Limeira , State of São Paulo, Brazil, thanks for all,
Thanks for your interesting comments, Paulo! It is exciting to hear that you have been able to set up a successful business featuring bird mouth joinery! Do you have a website where I could see some of your work?
thanks for helps thanks
very explained
Thanks for the comments, Pablo!
This is amazing
Hi Asad! Thanks for the comment. I hope that you give bird mouth joinery a try.
Very good video, and thank you for sharing. Maybe I missed it, but how do you determine the right bit height for the thickness of your board?
Hi davidhenry32 thanks for the excellent video I really enjoy it. 😀
I have a question, I'm creating a dodecaedron with 12 pentagons, the huge work is to cut the sides at 37.3 degrees. I check lot of possibilities but never think I could do it with my router, the only thing is I don't know if there is a bit for 37.3 degrees.
Can you help me undestand if I'm thinking the wrong way.
Thanks in advance.
Mario Acevedo
Thanks for your speedy replies, I was not expecting that. I am set for the height for the bits. I am really looking for what you recommend as the depth of cut for 3/8", 1/2" stock for the 6-sided bird's mouth bit and the 8-sided one? I have shared your videos with some friends of mind and they were as impressed as I.
Dave, I am interested in using bird mouth joinery to affix planks to a rounded ceiling as in a bus ceiling. It certainly has potential for me. What formula can I use to calculate the angle of the jointing cuts?
Great job!! I have a question, can I do that job using a 11 inches diameter barrel? if so, how I would do that?
Wonderful video!! Can you make more on other topics please?
Thank you, Joyce! I have ten other videos on my channel (davidhenry32) about a wide variety of topics related to bird mouth joinery. If you enjoyed the Introduction, you may find many of these interesting.
Just started watching your videos David, and I love your style. Question, can all BM bits be used for 2 different numbers of staves, ie a 6 sided bit can also make a 12 sided box, and an 8 sided bit a 16 sided box? Looking forward to watching more of your stuff.
+twoweary Hi twoweary! Thanks for your commenst and interest! The 6-sided bit can be used for 12-sided forms, but I've never figured out how the 8-sided bit can yield anything but 8-sided shapes. I've seen the claim made for 16-sided vessels from the 8-side bit by some bit manufacturers. In any case, if I were doing a 12-side or 16-side project, I would use a bit made for that that number of sides because size-specific bits yield the optimum joint, in which there is maximum stave-to-stave gluing surface.
Thank you Dave for your videos. Is there a catalog or book with the planters you showed in the videos? I would like to make a vertical planter/cigarette disposal decoration for between my garage doors.
Hi RMIGHTY1 - I'm very sorry, but I have nothing written about making the planters, and I have been asked about this before. I plan to put up a video about them, but other things keep getting in the way. I'll try harder!
Thank you so much for your excellent videos! Your careful and thorough explanations are much appreciated. (Are you a teacher/professor?) I look forward to attempting some birds mouth projects.
+John Shields Thanks for the kind words, John! Never been a teacher but felt that bird mouth joinery was very easy, and very much underused. Comments like yours are much appreciated.
David you wouldn't happen to have the plans for that planter you built shown about 39 seconds into the beginning of your video? I'd like to build one!
I was hoping to see what the sample would look like for the 12 sided . I have the mlcs bit for 6 and 12 sides . The directions call for 11/16 depth for 3/4 stock and just leaves an knife edge that wants to break off . Your video did open my imagination for other possibilities .THANK YOU
Hi Cole! Thanks for the comments and for watching my vodeo. Sorry, but I've never used the 12-side bit and can't be of much direct help. There's not much to do about that brittle knife edge problem except to not cut so deeply, which, of course, yields a less-smooth joint. That doesn't have to be a problem if you intend to round off the exterior of the project.
Dave, how do you keep from getting tear out when routing the end grain of the wood?
Wonderful instructional style David!
Is there any chance of you explaining the full procedure to assemble a long bird mouth mast section with; as an example a taper of 40% from largest diameter to smallest, as used in a free standing or cantilever boat mast.. Thank You!
Sorry, Paul! This would be bigger than I could handle, and I would have no use for it when it was finished. However I suggest you search CZcams for birds mouth mast building (try a variety of search terms) for the video you want. I have seen several videos dealing with masts over the past several years. Good luck!
Hi David,
I stumbled on your videos on the bird’s mouth router bits and found them extremely interesting. So interesting in fact, I immediately purchased Whiteside’s 6/12 sided and 8 sided bits.
Seeing those boxes through me over the edge.
I got the bits today and did a little playing with the six side one and have a question I could not find and answer to on the internet. The question: Once you start with the recommend bit height, how do you tweak the joint to make it fit properly. What do I move? The bit or the fence? And in what direction?
I did get it very close without going over but not sure how I got there.
Is there some general rule to follow to make joint adjustments?
All four videos are really done well. You need to do some more.
Thanks,
Jim Eller
I really appreciate your comments and questions! Re bit height adjustments: the height setting is the key. Getting it right is sometimes frustrating, however, because the height setting affects the required depth of cut. It is not possible to set a fixed height and then adjust depth for a perfect fit, unless you hit the height just right the first time. Especially since you are new to these bits, I suggest you do some ranging experiments with inexpensive wood, being sure that it is square and smooth before you start. With 3/4" stock, try height settings of 1/8, 5/32, 3/16, 7/32, and 1/4". In each case, cut depth to the best fit you can get. This will show you the effects of too-high and too-low settings and give an understanding of how to home in on a just-right height setting. Good luck! Let me know how it works out.
davidhenry32
Thanks David for taking time to explain. I'll give it a try. Like I said, the first time was pretty good following you video directions. I haven't moved the bit or the fence so I'm still in good shape for 3/4" stock. I will just have to buy another router and table for 1/2" stock and another for other stuff now so I don't have to move it :-)
I really admire those boxes. I'll be giving it a try.
Please conside making more videos on whatever woodworking subject. Your presentatiion skills are spot on for learning for old geezers like me
Thanks again,
JimE
@@davidhenry32 Thanks David, the set I'm using by Infinity Cutting Tools can be purchased with setup blocks for 3/4" stock this helps quite a bit. www.infinitytools.com/birds-mouth-router-bits-3729
Another one comment to focus your attention. Different cutting bits made in China are very cheap in relation to well-known brands. What is the difference between the two? Of course, I am very minimal amateur with woodworking my choice focusing to the chip bits. Thank's again very much for the tutorial.
damn they are hard to get . amazon said I would have here today the 24th dec checked delivery not tell jan 18th. went to woodline they are out.and no one else in town has them 6 to 8 week wait time . bye the way your work is awesome
Hi Dale! Pretty lame when Amazon won't meet their own deadlines. Sorry to hear it; very frustrating! Probably the Xmas Season. From my standpoint, their is a silver lining, that more people are apparently paying attention to bird mouth joinery. When you get your bits, I'd be delighted to hear (or see) how your projects turn out. Any problems, please contact me.
Dave, are you still making birdmouths and videos.
Like everyone has already said... this video is very good and we all appreciate your input on the subject! I have one question. What is the minimum thickness that a single stave can be, in order to use a birds mouth glue joint router bit? Please advise!
Mike Francis Hi Mike! Thanks for the comment and question.
In theory, there is no limit to how thin staves can be for BMJ to work. But, in my experience and as a practical matter, the properties of wood (e.g. chipping, splintering, warping), and the woodworkers technique and equipment, do force a lower limit. I have had good luck with projects using stock in the 1/4" range, even down to 3/16" thick. As you might expect, the height setting becomes quite sensitive with thinner stock and quite a bit of testing was necessary to get it just right. Also, some woods simply chip too easily to work well. That being said, with care and attention to detail, I'm sure thinner stock could be used successfully. Good luck!
I plan to use the BMJ bit for mugs and steins. I had been doing them with 15 degree bevels along each long side of the staves, but oh my, how tedious to do it that way. I just purchased an 8 sided bit and am now waiting for it to arrive. Each piece will receive epoxy glue ups, along with 3 coats of epoxy for encapsulation!
Mike Francis Very cool projects, Mike! I'm sure you'll be very pleased with how easily they go together using BMJ. If you get the opportunity, I'd enjoy seeing a photo of your work (via my website)!
Hello David
This is absolutely great videos in fact the only one on bird's mouth
Quick request on my side
Could you please do a video on 12 sides and also I would be very interested if you could do conic shapes??
Many thanks
Thanks for your nice comments!
Regarding a 12-side bit video, I have the bit but haven't used it much; maybe I should? But no immediate plans, unfortunately.
Conic shapes are a big and important subject; I have explored them some, but they're complicated and I haven't been able to come up with a good general approach. Your suggestion has started me thinking about it again, though. If you have any specific questions, perhaps I could help now.
Hi David
Thanks for your reply, I am looking to build a small table lamp and I was trying to find a video explaining how to do a comic shape for either a 8 or 12 sides
A video of the process , settings would certainly be useful.
Keep up the good work, it is well appreciated

Hi David. You have inspired me to try birdmouth joinery! I am hoping to start with 1/2" stock. Could you explain the height and depth adjustments for 1/2" as you did in the video for 3/4"? That would be really helpful to a total novice like me. Thank you!
Hi Luke! Sorry for the delay in replying. Glad to hear that you are giving BMJ a try. One-half inch stock works just fine with BMJ and is handled exactly the same as with 3/4" stock, except of course, that all the router settings are 2/3 of those that I talk about in this Introduction video using 3/4" stock. In my two most recent videos, making 8- and 12-sided bowls, I use 1/2" stock. It might be helpful to take a look at those (czcams.com/users/davidhenry32). Good luck!
Thanks David, I'll do just that. Keep up the good work! You've got quite the following!
Being a wood turner, do you know of this bit being utilized in the assistance of stave segmented bowl turning? Any links, or write ups on the pros or cons of using this bit as a method of creating a bowl / vase?
Hi Brenden! You are not the first to connect bird mouth joinery (BMJ) to turning. I have a friend who has turned a few small bowls from blanks I've made, and he said that it worked quite well (and they looked pretty good to me!). I've also had a few positive comments suggesting this application. And I've seen one or two videos where BMJ was used to construct musical drum bodies that were rounded by turning. However, I've not seen a video specifically demonstrating use of BMJ for turning blanks. In my opinion BMJ has serious potential for decorative turning; if I were a turner (or had a lathe!) I would certainly explore the area.
I just want this guy to be my dad..
I may have missed i,t but what do you use as a height & depth of cut for 1/2" stock for both 6 sided and 8 sided Bird Mouth Bits? Thanks. I think your videos are great and hop to see more. I am just a 70 year old beginning woodworker.
+spider one Hi Spider! Thanks for your kind comments and questions! For the 8=side bit, the rule of thumb for height setting is one-fourth the thickness of the stock. For 1/2" stock the height would be 1/8". For the 6-side bit I try to set height at a shade under one-half of the stock thickness i.e. for 1/2" thick stock the height setting would be a shade under 1/4". In both cases, as always, it is wise to check both height and depth settings with scrap stock before committing your final-project wood. Good luck with your projects!
Hi Dave, I have just purchased a 6/12 BM bit. In my 1st attempt, I played with the height and depth. Then I routed long pieces to be cut into desired length. My objective was to make a 12 sided vessel 6" in diameter. (1 11/16" x 11/16" staves). My problem is that my 12 pieces will form 2- 6 sided cylinders but not a 12. Depth of cut is 5/8". A bit deep, but still 12 pces should go together. Your thoughts?
Hi Jim! Thanks for the comments! You are not alone in being confused by the 6-12 dual BMJ bit. The problem is that the height and depth settings for making 12-sided shapes are quite different from those in my video, which only deals with 6- and 8-sided. At the time I made this video I had never tried the 12-side application. For 11/16" thick stock the height setting should be about 19/32" (quite high), with the depth at about 5/16". This is substantially different from the 6-side settings. Another important difference with 12-side settings is that the lower edge of the stave becomes the edge that continues to contact the fence after the piece comes through the cutter, not the upper edge. The upper edge will be unsupported, and probably feathered with wisps of wood that will require sanding to remove before gluing. I found it a bit hard to grasp until I tried it. I'm almost done with a video that hopefully explains it.
Please ask if you have more questions. Good luck with your project!
Hi Jim! In my earlier comment, about an hour ago, I forgot an important point. Not all 6-12 dual BMJ bits are the same. Some of the smaller dual bits, such as the bit I use for 6-side work in this introductory video, are limited to a stock thickness of about 1/2" when used to cut 12-side joints, if you want full glue joint overlap between adjacent staves, i.e. "just right overlap". The Yonico 6-12 bit, for example, is bigger and can handle stock thickness up to an inch or so.
when i was 7 or so years old my job was to churn the butter it was wood tapered wide bottom narrow top was homade by a craftsman in town i want to build one but do not remember the amount of staves any idea?
Hi William! I've never seen plans for the butter churn you describe but am sure they exist. Try a Google search for "wooden butter churn plans" and see where it leads you. Also, check out my video on CZcams on constructing a 12-sided decorative wooden bowl; the technique i use there would apply to constructing a tapered churn body. Good luck!
Hi, and thanks for a great instructional video! I read thru the comments, but not see reference to a minimum wood thickness. I would like to make some hex tubes using 1/4 inch stock. Doable?
Hi George! Thanks for the comment! In theory there is no limit to how thin the stock can be for BMJ. However, in my opinion, the practical limit is about 1/4" and that can be iffy depending on how splintery your wood is. BMJ leaves edges whose angles are smaller than 90 degrees, and these are prone to splintering with some varieties of wood. Any piece of wood where the grain is not parallel to the BMJ edge is a candidate for problems, also. Even with some splintering your hex tubes will hold together just fine, but the joints may not be as pretty as you want! In the past I've used 1/4" stock a few times but rarely go below 3/8" these days.
davidhenry32 Makes sense. I plan to use straight grain hardwood. I hope to construct a 1” tube. I expect to sand the outside edges. I will let you know how this turns out. Thanks again sir!
@@GeorgeIreton Hi George! Thanks for the reply; I am very interested in hearing how your tube turns out!
Could these bits be used to join pieces for segmented bowl turning? It just seems that the joints would be stronger and the sizes of the segments could be adjusted by changing the width of the pieces. I just have wheels spinning after watching this. I’m not saying it can. I’m just asking based on what I know and what I see. Thank you.
Hi Brooks! Sorry for the delay in replying. I'm not a turner but have seen many reports of the use of BMJ for turning blanks, and a friend of mine tried and liked it a few years ago. Give it a try!
David Henry Thank you so much for your input.
Urgent
Hi David can you tell what is the height setup for 7/8 thickness
Many thanks
As I now figure it, that would be 7/32" for an 8-side bit. However, your bit must have a long cutting edge at least 7/8" long for cutting a just right joint with 7/8" stock. That cutting edge on my Lee Valley bit is only about 13/16", 1/16" short. I have an 8-side Yonico bit with that edge at 1" long and it could handle your job. Other manufacturers might well be different. Or, of course, your design may not require just right joints and any bit might work. This is probably more of an answer than you wanted!

where can I get these Bird Mouth Bits? I am 58 year old beginning woodworker.I dont have a woodworking store close by that I know of, any help would be great help
Hi Thomas! Glad to see a beginning woodworker giving bird mouth joinery a try. I have bought all of my bits online.The green bit shown in the video are from Lee Valley (www.leevalley.com/US/wood/page.aspx?p=45160&cat=1,33084,46168,69435,46174). For a selection of different brands and prices, try Amazon (www.amazon.com/s/ref=nb_sb_noss_1?url=node%3D328182011&field-keywords=bird+mouth+router+bits).
Good luck with your work! If I can answer any questions, please ask.
I can see I`ve got to buy some new bits
Go for it, Louis! I think you'll be glad you did!
Hi trying to learn and do some woodwork for hobby is it possible to do hexagon or octagon but top more open than bottom like a fruit bowl
Hi Athanasios! Thanks for the question; you've touched on an area of great potential importance for bird mouth joinery. I have planned for years to do a video on use of tapered staves (which results in the tapered vessels that you ask about) but haven't yet put it together. I suggest two things at this point:
1. Go to the Lee Valley Tool website and go to their page on bird's-mouth router bits . On it there is a link to multipage instructions on how to use tapered staves; it is very useful.
2. Try using staves with only a small taper (opposite sides of the staves up to 5-10 degrees out of parallel) for some projects. My experience is that small tapers don't affect the joinery enough to be noticed, yet the small taper makes a big difference in the appearance of the project.
Good luck with your woodworking!
if you check out the Lee Valley Website the instructions for the bird mouth bits discusses tapered projects will all the appropriate calculations
davidhenry3
Does this bit work on half inch lumber to
Hi Harry! The bits used in this video can be used for stock of any thickness up to 3/4" to give full overlap joints, as described in the video. As a practical matter, adjusting the height and depth settings of the bit gets tedious for stock much smaller than 1/4". Larger bits are available that work on stock up to 2" thick.
Do these come with 1/4 inch shank?
I don't recall ever seeing 1/4" shanks for bird mouth bits.
qual o nome dessa fresa que você uso?
Hi Manu! The router bits that I call bird mouth router bits also have several other names. In the Lee Valley online catalog they are called bird's-mouth joinery bits (I use these mostly for my work). On Amazon, searching for birds mouth router bits will find a variety of other suppliers. Doing a Google search on bird mouth router bits will find more. Good luck! I hope that you find what you want.
Oi Manu! Os roteadores que eu chamo de aves fresas boca também tem vários outros nomes. No catálogo on-line Lee Valley eles são chamados de bits de marcenaria pássaro-boca (eu uso isso principalmente para o meu trabalho). Na Amazônia, em busca de fresas boca pássaros vão encontrar uma variedade de outros fornecedores. Fazendo uma pesquisa no Google sobre fresas boca pássaro vai encontrar mais. Boa sorte! Espero que você encontrar o que deseja.
Can this be used on tapered stock to make a wooden boat mast?
Hi Paul! Definitely yes! Masts were one of the earliest uses of this technology. There are several videos on CZcams demonstrating how this is done.
@@davidhenry32 I'm guessing the B. 8 side bit is for masts?
Makes sense, Paul, but I haven't paid that much attention. With more sides, less wood must be removed when rounding.
M UM BELO TABALHO.
+Luiz Antunes Muito obrigado por seus comentários gentis e para assistir meu vídeo!
With this cut can I make a play ground sand
+Johan Larios Hi Johan! For some reason I don't think that your full comment was posted; care to try again?
Do they come for say, 12 sides?
+Juan Gómez Hi Juan! Commercial bird mouth router bits are available for making 6-, 8-, 12- and 16-sided shapes. 6-side bits are usable for making 12-sided shapes but they vary in how useful they are for the 12-side application.. I recommend the Yonico 6- /12-side bit; it works well for thicker stock.
+davidhenry32 Oh! That's great, I'm working on a project that involves stave construction and have been beveling both edges of each board to make them. birdmouth joinery seems like a much stronger and easy to make joint. I'm gonna give it a try. Thanks! PS: Your presentation is excellent! Very well explained and educational.
+Juan Gómez Thanks for the comments and good luck with the project!

Putting a strip of 1/2” MDF along the top attached with double sided tape is how you overcome the problem when the piece is nearing completion will aid in running the piece along the fence and prevent it from feathering.
