A description of fixtures and devices I have used to cut RH and LH wood threads . Includes tips on reproducing and repair of damaged wood threads on antique plow planes.
The v-tool for cutting the threads makes perfect sense, now that I've seen it. The 60º bit for cutting threads on a metal lathe doesn't work well in wood, of course. Your method for copying an existing thread is ingenious--simple and straightforward. You are indeed a wealth of knowledge, and I'm so glad you're documenting these things for future generations.
I hear that a lot but every source I've found all the way back to PopMech ~1940 refer to a 60° angle and have yet to see a failed thread that wasn't due to wood selection or abuse. I'm genuinly curious where this tidbit of "common knowledge" comes from
You sir are a true one of a kind craftsman I can truly say it would be an honour to say that working with you would be a dream come true. Your videos are or should be saved for all who in the future want to learn. It's impossible to put into books your skill.I feel very lucky to be able to watch what you are showing thank you so much. It's a shame I'm retired now and it's a bit late that I could use a lot of the skill you are teaching but I have a little work shop and will put some of it to good use .Thanks again
Hab mir schon eine Menge Videos zum Thema Gewinde in Holz schneiden angeschaut, das ist mit Abstand die beste und einfachste Methode das zu Machen Es ist wiederholbar, leicht zu modifizieren und sehr verständlich erklärt er hat es einfach drauf Hut ab ich bin, total begeistert von so einem alten Hasen kann man noch viel Lernen simpel und einfach genial.
This is extremely helpful. I’ve been trying to cut threads in purpleheart, and having a lot of issues with it. The cutter that came with my tap/die set has the same little nib on the tip that you showed. I’m going to sharpen that off and see how it cuts now.
You are certainly a wealth of information on threading. I haven’t made any wood screws yet but I plan to. I recently bought a metal lathe which I have not used yet. Some of your video and explanation are above my head at this point but I plan to do more research and experiment with some of your techniques. I’m sure I’ll have some questions as my experience grows. Thank You for sharing your knowledge.
Hi Paul, I was wondering what do you use as a guideline for deciding what lead you are going to use for a given size of thread? Say an 1-1/2" dowel what lead would be suitable for that size? I have seen most wood threads and they use a much coarser pitch than metal working threads. They also seem to have an more rounded crest on top of the thread. Have you ever tried using an Acme thread pitch on wood dowels? If so how well did it work? That thread seems to have a better profile characteristic for wood than V thread?
Paul my experience on the larger diameter wood screws like used on mitre blocks,clamps,or bench screws vary from 6 to 10 TPI. I think it is just the makers choice, I am not aware of a magic formula . I remember several years ago someone manufacture a large diameter acme style thread with a flat top , it was a flop as the threads chipped and broke compare to the traditional 60 degree vee threads.
Thank you so much for taking the time to share this. This channel is exactly what I need right now to debug my screw box project. I just learned more than I had ever expected to know and am grateful to be a steward of your lifetime of experience and wisdom. I am looking at an old book on turning and one of the plates shows a screw box that has two v cutters mounted inside. Do you know if having an extra cutter will make any significant improvement in thread quality or will it just be another thing to sharpen?
You sir are a true one of a kind craftsman I can truly say it would be an honor to say that working with you would be a dream come true. And I myself also made wooden screw with the similar idea as you did in this video. For the reference czcams.com/video/NUBG1SJOUJM/video.html Only the difference is that I used wooden trimmer rotating in high speed by electric motor ,instead of The v-tool . The wooden trimmer could process relatively small wooden column. On the wooden column surface (D=11mm), the combined system could make thread ( M12mm, P=1.75mm, Depth=0.7mm) successfully. Thanks a lot.
Probably to big for a single cutter, it would require two cutters. I would probably use a screw cutting metal lathe with a laminate router mounted on compound. Google Beall woods threads.
Hi Paul. With the V-carving iron you recommend to make the first cut 90 degrees. However, the cutting iron for the threads is back-ground. Why do you do that? At what angle does this rear grinding have to be made?
Paul, maybe I have expressed myself a little too little precisely. I'm referring to the video «sharpening a V-gouge without stones» Where you show that the first grinding should be made 90 degrees to the back of the V-gouge. I understand that. When I look at the cutting irons for the production of threads, I realize that this first grinding was not made 90 degrees but 60 or 45 degrees or.... to the back. Why do you do it this way and what angle for this first grinding do you recommend.
I was wondering weather you have ever made a worm screw and cog. And if so, i would love to get some tips if possible. I was thinking a larger screw thead would be best i was planning on making it 2" dia. If you any advice that would be appricated. And thankyou foe your video, as has being mentioned. Your wealth of experiance is a pleasure to see and learn from. Cheers Simon.
do you have a screw cutting metal lathe ? if not you could build a large version of the screw box and mount a laminate router in the top of the sides of box to cut the male threads. the internal threads would be cut as indicated in the video except at a larger scale.
@@paulhamler8315 thank you :) Do you make that cutter your self, and if so, how do you match up the angle to the v-cutter used for the external threads? I imagine that angle ultimately chances it is adjusted on the plate?

Thanks for the kind words.
This is perfect timing, I'm starting on my roubo style workbench soon and I want a big wooden screw for the leg vice. It's like you read my mind.
Great work and awesome explanation of how you were doing your work. Thanks so much!!
Absolutely amazing!
Thanks for sharing, very informative and easy to understand, excellent narrative. Looking forward to more .

I can't thank you enough for sharing what you know!
Thank you for passing on this knowledge.
Wow,
Thank you so much for this documentation
Thanks Paul, very informative and interesting!
This video is solid Gold.
as always pure genius can't wait until the hinge video
Very interesting. Nice technique.
Very good Paul!!!!!!
Top quality CZcams content.
Great work. Would love to learn to do this. Thanks, Robert

I have never made a box using two screws because o the scale I work. My thoughts would be it would only be necessary or very large threads.
How long has it been since you purchased the v cutter for a wood box from woodcraft you mentioned in your video on youtube

This is authentic! Does the screwbox scale up to make thread for a woodworking vise? How would you make the leadscrew in that case?
Probably to big for a single cutter, it would require two cutters. I would probably use a screw cutting metal lathe with a laminate router mounted on compound. Google Beall woods threads.

Why you didn’t it with the normaly metal lathe ? Would'nt be simpler ?

Exceptional explaining of the wood screw. It gave me more ideas to improve. My wood screw jig. Thank you.
I tried to find the video you described for sharpening the "V" cutter. Is it still available?
go to my you tube channel click videos it;s still listed

Hi Paul.
What do you use for a cutter for the tap?
12L14 or 01 air hardened steel
@@paulhamler8315 thank you :)
Do you make that cutter your self, and if so, how do you match up the angle to the v-cutter used for the external threads? I imagine that angle ultimately chances it is adjusted on the plate?
how small wooden bolts have you made ?
sorry i got excited. thanks for sharing
1/8 inch (.125)
Isn't that a good 6 to 8 inches of dead space betweent the last thread and the head of the screw?
doesn't bother me I have a lathe
@@paulhamler8315 apologies, maybe. Not understanding...
So, you'd finish up those last few 6 to 8 inches and thread them on the lathe?

could you do a little better job with your critique and articulate the point in the video you are referring to.
