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. 👍👍👍

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.

I am still laughing. A bar in a bar and a dog with two... Love your work and humour as always Matty.

That's one heck of a boring bar mate. Bloody beauty...

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

very cool build ... there are very few feelings about machining that are better than seeing the imagined tool work beautifully

very good job matty..thanks for your time

Agreed, let the young bloke show his expertise with the GTAW, make his dad and his instructors proud.😊

that's one nice boring bar mate.

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.

Another great one Matty. Ernie.

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!

Nice one Mate great job

That insert cut pretty clean and shiny..

I like your "bar in a bar" idea!👍 Cheers, Matthew

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.

If you don’t have a tool make it. That’s why you’re a machinist. Thank you for the video. Thank you Sir

Another brilliant video.. 🧑‍🔧

Well done mate 👏 👍

G'day Matt,, another successful build!! also very inspiring cheers

Awesome result, well done, where there is a will, there is a way 👍

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.

I’m absolutely making one of these! Thanks, Matty!

Great video Matty, thanks

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.

Pretty slick changes clamps on the move.

Wonderful approach and love the results.

Excellent job Matty, great video, keep'um coming..

Well done Matty.That is a fantastic solution to the problem and simple. Don’t forget to cover the welder back up 😂 😂

Awesome boring bar build! Great video!

Kerja bagus saudaraku ♥️♥️

Nice project, but if you want a better surface finish, hone the bore to finished size. Cheers, Mick.

Nice work! Enjoyed, thanks.

Turned out great, nice one! I like the way you chamfer too, good control over the two handwheels, cheers, Dave

Great Job, even better Tool!

A true craftsman! Thanks for sharing 🇨🇦

I like the way you use the vernier.

Awesome great job!! Very creative

Parabéns é sem dúvidas nenhuma um belo porta ferramentas 🙏

That ought to work Matty, well done mate. Cheers, Jon

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.

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!

G'day Matty, bloody beauty again mate, honestly you've graduated into a fantastic tool maker 🤘

Great build Matty, glad it worked even better than you were hoping for. Cheers Tony

So funny when he "strokes" the shaft!😮😂

Very precision..

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.

Now ya got me wanting to make one thanks!

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.

Thanks for sharing. The ugly welds are the strongest.

Nice build...

Nice build/results…good job!

Very nice matty, the bulky size of the bar is also a factor in the precision.

That is a nice strong boring bar, Matty! I shall make one just like it. It will be a nice addition to my tooling!

That's a monster boring bar! Nicely done.

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😁)

Nice one Matty

G'day very cool build Matty

Great work Matty. I had no doubt it would work perfectly. Nice one. Cheers Nobby

That's a good-looking boring bar

Hi Matty, quick change toolpost will solve the problem, no more shims.

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

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 👍

I don't know why you doubt yourself!

Turned out great Matty 👍👍 Nice idea using the small bar...big time saver Cheers....Dean

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!

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!👍👍😁

Well, that's a big one :) And even if the welds doesn't look 100%, It works. That's what counts.

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

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.

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!

Nice job

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.. 🙂

Beatifull mate !

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.

There is no humour like “Aussie” humour. 🐕 I hope I catch you around the traps one day, , enjoying your content. Thanking you 🤝🏻

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

I would love to see the dog. 🤔🤣I love your work and sense of humor. Great stuff! 👍

Jeezz MATTY, fingers like sausages and you turn out this kind of engineering.

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.

Matty -- Nice going. A Ridgid Boring Bar solved your problem. --- Jim

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

Matty...measure twice, cut once....you know how it goes

"These calipers are great!" *bang *bang *bang

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 👍🇦🇺

if you aren't making mistakes, you aren't doing anything. Period

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

Superior outcome Matty. Did you fling coolant all over the shop during that last boring pass?

Hi Marty, just watched this boring bar build,, very good,,, How are you going after the opp, hope you are doing well, regards Frank

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.

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

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

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.

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.

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.

2nd go around Matty, lol gotta build me 1....

Great build and results. I like the concept, and out side the box for sure 😎. Will you blue it??? Bear

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!

Hi Matty, I'm a new subscriber, I really enjoy your video's! Just out of curiosity, when will you be starting the restoration of Cutting Edge Engineering's KLOPP 1000H Shaper?

👍👍😎👍👍
