- Gday, This video I made new boring bar, The others I have don't have enough rigidity to do a 100mm long bore, I made this from materials I had laying around, I hope you enjoy the video and thanks for watching, Cheers

Another great one. Thanks Matty.
I worked 20 years with my old man & one of his frequent sayings was “A man who never made any mistakes, never made anything!”
In his value system - it wasn’t the fact that you made a mistake that mattered, it was the ability to overcome your mistakes is what mattered.
You undoubtedly learned something from the minor mistakes in this one, but the best part is that we too can learn (hopefully) from your mistakes, because you do the honest thing & include them, whilst many others might edit them out.
And you overcame them and achieved the desired outcome.
It’s one of the many aspects of your vids that I really enjoy.
Keep it up please. 👍👍👍
Gday Ian, I’ve always showed mistakes and for the reasons you mentioned, there’s always something to learn from each one, I’ve learned a lot from fixing my screw ups, appreciate your kind words and thanks for watching, cheers
I am still laughing. A bar in a bar and a dog with two... Love your work and humour as always Matty.
I thought this would make a few laugh, mate I was pretty happy, thanks for watching
Matty this was fantastic! a couple of ideas for you - tig mig the bottom of the holder and then skim the thickness of the shims so you dont have to worry about what ones to grab and had all of that piss around. maybe consider drilling a through hole that exits just before the end and an angled hole to the insert for through coolant. the last is a trick that might work on this or another build is to drill a small bore for grease and put a nipple on the back end and pump tight with grease for more rigidity and/or a neat hole and pack lots of same size carbide blanks or broken endmills down it and then cap off with a bolt.
Gday, I didn't read the callipers correctly and turns out its only .015" to low not .150", The through coolant is a great idea and I should do this, Thanks for your advice mate, Cheers
Agreed, let the young bloke show his expertise with the GTAW, make his dad and his instructors proud.😊
Gday, I really need Trent to give me a couple of lessons, I only have a scratch start tig but one day ill upgrade it hopefully, Thanks for watching, Cheers
Very interesting video.
But you'll have to get your young one to re-do the tig welding. It's playing havoc with my ocd. 😵💫
✌️ Peace from Melbourne 3810.
That's one heck of a boring bar mate. Bloody beauty...
Thanks, it works pretty good mate, thanks for watching
I really enjoy watching tools being made to do a job. A great way to see someone else's ideas at work. The dog reference almost made spit out my morning coffee, so I'm stealing that to see if I circulate it here in Canda. Thanks for sharing
Gday Ken, I’m really happy with how this boring bar turned out, hopefully you get some laughs with the dog phrase, thanks for watching mate, cheers
very cool build ... there are very few feelings about machining that are better than seeing the imagined tool work beautifully
Gday, It was a good feeling when the bore turned out spot on, I didn't expect it to work as good as it did, thanks for watching, Cheers
@@MattysWorkshop if you have sound ideas and a good understanding of what you are trying to acheive , more often than not it will work.... I think the "This is a daft idea but it might work" ones that do work are better but only just..
Beautiful work and craftsmanship!
Can't beat a beefy boring bar. It is amazing to see the tool pressure deflect a bar when it starts in the bore on videos. So the bigger the better.
Gday Tom, it is amazing how much a boring bar deflects when it starts in the bore, thanks for watching mate, cheers
Kerja bagus saudaraku ♥️♥️
Thanks mate, appreciate you watching, cheers
Parabéns é sem dúvidas nenhuma um belo porta ferramentas 🙏
A true craftsman!
Thanks for sharing 🇨🇦
Cheers Paul, appreciate you watching mate, cheers
very good job matty..thanks for your time
Thanks mate, appreciate you watching and commenting, cheers
Awesome great job!! Very creative
Thanks Don, appreciate you watching mate, cheers
Awesome boring bar build! Great video!
Thanks very much
Another brilliant video.. 🧑🔧
Thanks very much Mike, Appreciate you watching and commenting, Cheers
Great video Matty, thanks
Thanks very much Robert, Cheers
Awesome result, well done, where there is a will, there is a way 👍
Thanks very much mate, Theres always a way around things, Thanks for watching, Cheers
Great Job, even better Tool!
Thanks very much, cheers
Another great one Matty. Ernie.
Excellent job Matty, great video, keep'um coming..
Thanks mate, im hoping I can get back to regular once a week videos again , cheers
Very precision..
Thanks very much, cheers
I like the way you use the vernier.
Tools that make new tools as a great way to spend some time. For months ide been complaining about the lack of thick washers but today I made some. Simple job but feels better rather than buying.
Gday Nigel, it’s always better to build then buy in most cases, it’s definitely more enjoyable using a tool that you’ve made then a shop bought tool, thanks for watching, cheers
Nice work! Enjoyed, thanks.
Thanks very much John, appreciate you watching, cheers
Wonderful approach and love the results.
Gday Robert, it was the easiest way I could think of making it without making it to complicated, thanks for watching, cheers
Well done mate 👏 👍
Thanks mate, first commenter too, Top job, Cheers
Nice build Matty. This will be a nice tool addition to your collection. Love all your tool building videos. As a beginner they will help me a lot.
Thanks for sharing.
Gday Joe, great to hear the videos are helpful, just have a crack mate, cheers
Great build Matty, glad it worked even better than you were hoping for. Cheers Tony
Gday Tony, I definitely worked better than I expected, thanks for watching mate, cheers
Nice build...
Thanks very much Jerry, cheers
I’m absolutely making one of these! Thanks, Matty!
Go for it mate, Cheers
Pretty slick changes clamps on the move.
Thanks for watching
Nice build/results…good job!
Thanks Chuck, appreciate you watching, cheers
Nice one Mate great job
Thanks very much mate, Cheers
I like your "bar in a bar" idea!👍 Cheers, Matthew
It was the easiest way I could think of doing it and now I can change the ends out for different type inserts, Thanks for watching, Cheers
Top notch build! Deflection is the enemy as I am quickly learning. Ive bought a couple of boring bars that are the biggest diameter that will fit my holder. They are all coolant ready which I am not set up for yet, it seems that might help with the finish. Im having the opposite problem now as I am trying to thread a bar for my gear cutting setup to hold the gear in my rotary table. All my inside threader bars are barely too big. Time to order some micro tools. I truly appreciate all the knowledge that you freely share. Much better than college knowledge and much cheaper. Thanks again for all the work!
Cheers from across the pond!
Gday Jim, coolant definitely helps with surface finish, it was very noticeable on this bore, appreciate you watching and commenting mate, cheers
If you don’t have a tool make it. That’s why you’re a machinist.
Thank you for the video. Thank you Sir
Gday, Its definitely better being able to make your own tools as required and much cheaper too, Thanks for watching, Cheers
That insert cut pretty clean and shiny..
It left a brilliant finish, way better then I was expecting, Cheers
That's a monster boring bar! Nicely done.
It works pretty good mate
A person shouldn't be judged by mistakes, but how they deal with them.
What you are doing is "Prototyping", "Concept Development", "Conceptualization", "Experimental Modeling" and many other terms.
These terms are used to describe the "Learning Curve" by the unskilled, usually "Pitchmen".
I am assuming you and I and other viewers are of the same bent, we build and fix stuff.
I admire you showing what you call "mistakes".
I see them as pointers and helpful hints.
One technical question: what material was this boring bar?
It seems to work well.
I've always been torn between softer materials that absorb shock and don't resonate versus harder materials.
Now ya got me wanting to make one thanks!
Definitely make yourself one mate
Nice one Matty
Thanks for watching mate, cheers
G'day very cool build Matty
Thanks very much mate, cheers
I don't know why you doubt yourself!
Always been the same mate
G'day Matt,, another successful build!! also very inspiring cheers
Gday Graedon, This build was a winner mate, It worked better then I was expecting, Thanks for watching, Cheers
Recently did similar. I used a length of shaft stock that included a 3/8” key way that oriented to top of the bar, and used keep the bar rotation indexed in the mounting sleeve, with keyed shaft collars welded to both ends of the sleeve. Unintended benefit is being able to run coolant down the key way on top of the bar as a trough, to the cutting tool, on deeper inside turning setups.
Gday, Thats a great idea for getting coolant to the insert, Might have to do something similar, Cheers
Thanks for sharing. The ugly welds are the strongest.
Gday Sam, if that the case these welds will never break, thanks for watching mate, cheers
Nice job
Thanks for watching
Turned out great, nice one! I like the way you chamfer too, good control over the two handwheels, cheers, Dave
Gday Dave, Im slowly getting better at chamfering and it is a lot quicker to, Thanks for watching, Cheers
Well done Matty.That is a fantastic solution to the problem and simple. Don’t forget to cover the welder back up 😂 😂
Gday, Its a simple design and it works, The cover went straight back on mate, Thanks for watching, Cheers
That ought to work Matty, well done mate. Cheers, Jon
Gday Jon, it worked way better then I expected mate, appreciate you watching, cheers
Great work Matty. I had no doubt it would work perfectly. Nice one. Cheers Nobby
Gday Nobby, it worked better than I thought it would, thanks for watching mate, cheers
that's one nice boring bar mate.
Thanks very much Warren, pretty happy with how it turned out, Cheers
Good build Matty! I thought you were going to machine a seat for the insert directly on the big boring bar, but adding a slot for a smaller boring bar is brilliant.
Gday, Have the slot I think will be handy in the future to use different bars in, Bit easier making it his way too , Thanks for watching, Cheers
Beatifull mate !
That is a nice strong boring bar, Matty! I shall make one just like it. It will be a nice addition to my tooling!
Gday, definitely make yourself one mate, go your hardest, thanks for watching, cheers
Nice project, but if you want a better surface finish, hone the bore to finished size.
Cheers, Mick.
Very nice matty, the bulky size of the bar is also a factor in the precision.
Gday, Its definitely rigid compared to the other bars I have, Thanks for watching mate, Cheers
This is a great technique 👌 Although, I don't do anything that large. It's nice to have this technique in case I need it. Thanks for sharing 👍
Gday Craig, I’m finding I’m slowly doing bigger jobs as time goes on, thanks for watching mate, cheers
That's a sturdy looking bar. Don't beat yourself up about the weld quality. It looks plenty strong enough. The beautiful welds come with loads of practice. I used to be able to TIG really well, but having not done much for 20 years i can make a strong weld but not a pretty one!
Gday Olly, the welds are strong enough, they just look shit, I only have a scratch start tig and one day I upgrade hopefully, practice is what i need, thanks for watching mate, cheers
Turned out great Matty 👍👍 Nice idea using the small bar...big time saver
Cheers....Dean
Gday Dean, turned out better than I expected and it works, thanks for watching mate, cheers
I didn't mean to criticize you in any way. By saying "if you aren't making mistakes you aren't doing anything" I meant that for myself. Your mistakes are nothing compared to what I can do. Actually, I wouldn't even call yours a mistake. I really appreciate your channel, thank you.
Don’t stress mate, I make plenty of mistakes and that’s the best way to learn and this is why I show them in the videos, someone doing the same thing can learn not what to do….
Brilliant idea Matty, I made a similar tool post boring holder 40mm bore for a proprietary screw threading bar ( quite cheap off ebay, ref to big for hobby use), the only difference was using the bar as a mandrel to machine the tool post stock.
Definitely a job on my list.
Thanks for sharing.
Best regards from the Black Country UK 🇬🇧.
John.
Gday John, I had intentions of using the bar as a mandrel but I screwed up the dimension a bit so that didn't happen, Thanks for watching mate, Cheers
@@MattysWorkshop Hi Matty, I heard you say about not using it as a mandrel, but clamping it on the mill would have been fine. Again very nice bit of kit, maybe some deep drilling is next?
Isn't it the coolest feeling when you make a tool for yourself out of what's on hand? The equivalent commercial unit we can get from a national supplier here is about $270, and that does not include the bar holder. Nicely done!
This boring bar worked better then I expected and was an easy simple build, much cheaper to mate, cheers
That's a good-looking boring bar
Thanks Chris, appreciate you watching, cheers
G'day Matty, another great addition to the shop and once again all hand made. To make it even more rigid I would put another flat on the bar at 90 degrees to the first one and add another 3 grub screws. Locking in two directions would take out all the radial play from a loose fit adding more rigidity to the job.
Cam
Yes I thought the same thing to overcome the slight overshooting of the bore size.
Gday Cam, I think I will put the second flat and add more grub screws, it felt rigid as is but more aren’t going to hurt, thanks for watching mate, cheers
So funny when he "strokes" the shaft!😮😂
Very good job! Love the idea of mounting a smaller bar in the bigger one. Your TIG welding is better than mine (I've never tig welded, only gas brazed😁)
Gday Robert, Making it this way was the easiest way I could think of and the quickest, Now I can change the ends out for different bars if needed to, I certainly need a few lessons on the tig, Thanks for watching, Cheers
Great build! Necessity is the mother of invention ! I built a small press one time to remove a bearing only to find out the piece holding it on actuator screwed off!😡Now you have something to tackle bigger jobs in the future. Keep up the good work and Stay Safe!
Gday Allen, I bet you weren’t real happy when you worked out it wad screwed on, thanks for watching mate, cheers
G'day Matty, bloody beauty again mate, honestly you've graduated into a fantastic tool maker 🤘
Gday Ralfy, I reckon I’m still in kindergarten mate, I got lots to learn yet, thanks for watching, cheers
This is why I enjoy your videos out of the box. Id have thought you might have tried line boring mounting the part on the saddle. OR using the mill either way then using a cylinder hone to finish off. Love what you did.
Gday Raymond, one day I’d like to have a go at line boring but not on the lathe, thanks for watching mate, cheers
I would love to see the dog. 🤔🤣I love your work and sense of humor. Great stuff! 👍
Gday, if I find the dog I’ll take a photo for ya mate, appreciate you watching, cheers
Hi Matty, quick change toolpost will solve the problem, no more shims.
Gday Willem, A QCTP would be good but I can't afford the one I want, One day I might get there, Thanks for watching, Cheers
There is no humour like “Aussie” humour. 🐕
I hope I catch you around the traps one day, , enjoying your content. Thanking you 🤝🏻
Thanks mate, appreciate you watching and one we might cross paths, cheers
G'day Matty, there's nothing wrong with with winging it if it works mate! Great build with excellent results, so I'd call that a bloody big win. Cheers from the UK. Sam
Gday Sam, almost all my builds are on the wing’it scale, not everything goes to plan but that’s the fun of it mate, thanks for watching, cheers
"These calipers are great!" *bang *bang *bang
There strong to mate, thanks for watching, cheers
👍
Thanks for watching mate, cheers 🍻
@@MattysWorkshop luv ya work fella I follow many a channel have the same machines as you but not the big mill the little mill drill does what I want you're the only channel I comment on that being said I should give preso some love lol cheers fella
if you aren't making mistakes, you aren't doing anything. Period
Gday Glenn, plenty of mistakes made here mate, im only human, thanks for watching, cheers
I’d hone that bore .. the process will show the deviations ( tight spots ) plus it changes the finish to longitudinal vs. radial …. A radial finish will eat a seal… if it doesn’t roll it first
Thanks for watching, cheers
Brilliant work as per usual.. One thing you could look at is installing some fo those fancy multi-coloured LED lamps. Get some light into those dark corners.. 🙂
Gday, I really need to do something about lighting, it’s on the to do list, thanks for watching, cheers
Well, that's a big one :)
And even if the welds doesn't look 100%, It works. That's what counts.
Gday, I really need to practice tig more, the welds were definitely ugly, thanks for watching, cheers
Matty...measure twice, cut once....you know how it goes
Gday, I normally do that in reverse, thanks for watching mate, Cheers
Another great set of jobs mate. I agree with troyam6607, build up the base of the tang and mill it back to size. Have a good one mate 👍🇦🇺
Gday Mark, turns out it’s only 15 thou low so won’t be hard to fix, thanks for watching mate, cheers
Matty that was great! I really enjoyed it.
Your tig looks just like mine... the saving grace is that although our welds look a bit rough, they are still strong enough to hold.
Gday Simon, one day I’ll have a peddle tig and I’m completely over the scratch start shit, thanks for watching mate, cheers
@@MattysWorkshop Mate I hated scratch start, at my Mens Shed we have HF start which you will love.
I don't use the pedal and they are expensive as well.
Prob mainly used on ally and I assume you don't do much ally.
Hi Matty enjoyed the video, great idea with the bar in a bar. I would probably shim the little bar rather big one up if it's only a few thou and you can, then you would only need to do it once
Gday Paul, that’s a great idea to shim the small bar, thanks for the tip mate, cheers
@@MattysWorkshop gday Matty, glad the idea is useful and thanks sharing the build
👍👍😎👍👍
Thanks for watching mate, Cheers
Jeezz MATTY, fingers like sausages and you turn out this kind of engineering.
Definitely snag fingers here mate
G'day Matty Now that is a very nice boring bar holder, for the size & length of the I.D. that was being bored, there was No Way there would be any chatter lol😂😅😊
Nice job, well done
Gday Ted, I definitely got rid of the shatter finally, the idea worked mate, thanks for watching, cheers
now run a bore right through it, tap the other side with a barb
now you run lubricant through the center of the bar right into your work piece
With the slightly oversize holder. Are you going to drill and tap 90 degrees to the top holes more set screw holes to pinch the bar in 2 directions. Might be interesting to hollow the holder bore in the middle. So the clamping pressure is on the ends. Not rocking in the middle like a teeter totter.
Gday, so far I haven’t noticed any rocking of the bar in the holder, off camera I took some heavy cut with no worries at all, relieving the centre portion of the holder is a good idea to make sure there’s definitely no rocking, thanks for watching, cheers
Good resuly Matty. I know I have some bars that have quite a lot of deflection in them. I do have a 16mm Tizzet one that is very rigid. Not sure what it is made of but it's heavy. Maybe carbide.
Regards.
Steve.
Gday Steve, if it’s heavy I’d say it carbide, thanks for watching mate, cheers
it always makes me wonder why boring bars dont have extendable bearing posts coming out behind the cutting head so you basically get a steady rest riding the ID of the job after the cut. it seems like an easy way or reducing the chatter. have you ever tried this? my first thought would be either manually set up, or like a 3 jaw chuck wound by rod from back of bar.
Bout time ya clean out the bin and make something!🤣🤣🙄
Just fun in ya mate, ya know im the same way when it comes to buying a tool that you know ya can make. Besides its really makes ya feel good too, when it works probably better and lasts longer and it didnt wipe your visa card out in the process. Well done Matty!👍👍😁
Gday James, nothing better then using tools that you've made yourself, Buying tooling can get out of control fast but that doesn't happen her cause there isn't the coin there, Thanks for watching mate, Cheers
@@MattysWorkshop Wouldn't have it any other way mate,watching your videos at 430a.m. having my coffee as usual,being retired has it's privileges...LOL
Thanks for sharing your toy building skills👍
Matty -- Nice going. A Ridgid Boring Bar solved your problem. --- Jim
Gday Jim, you can’t beat rigidity mate, thanks for watching, cheers
2nd go around Matty, lol gotta build me 1....
Gday, this is a really easy build, im tempted to make a smaller version one day, cheers
👍💪✌
Thanks for watching mate, Cheers
@@MattysWorkshop Thanks for posting these great videos Matty!
G'day Matty, thanks for your videos. I enjoyed this one, but Kurtis at CEE did a video on making a monster Boring Bar some time ago. You might pick up a trick or two. That said, I do enjoy your work and your determination. Cheers.
Gday Ken, I did see the big boring bar CEE made and it’s bloody big, appreciate you watching and commenting, cheers
Good job Matty, 2 points only, 1. I hope you got good grubscrews, the garbage they're selling lately ruin a good job, especially when the inhex strips or is too shallow. 2.quite a colourful turn of phrase re: the dog, brought a good laugh on. Cheers mate
Gday Jay, The grub screws aren't to bad in the kit I got, I was pretty happy when I said that phrase, Thanks for watching mate, Cheers
Great vid once again! One day could you show your hand movements when you're chamfering parts? I've tried to replicate your process on my lathe and, well, it wasn't pretty!
Gday Bill, it took me a while to get used to doing the chamfers like this and it’s a lot quicker this way, I’ll try and show how I do it mate, cheers
Superior outcome Matty. Did you fling coolant all over the shop during that last boring pass?
Gday Preso, no much went on the floor surprisingly, thanks for watching mate, cheers
I was wondering if you could cut a thin slot on the top of the boring bar to channel the coolant to the tip soyou wouldn't have to worry with the tip of the coolant line?
Gday, I'd say that would work for sure, Thanks for watching, Cheers
