Making a portable line boring machine! Shop made. Final! It’s finished!

A proper engineer making his own tools, not unboxing sponsored new ones. Nice editing too.

I winced as soon as I saw that piece of steel fall. Im sure your first reaction was "hopefully the cable isn't nackered" but we know the cable is always nackered. Keep up the good work fella.

Enjoyed the series. Now looking forward to the maiden voyage.

Necessity being the mother of all invention! A brilliant piece of "on the hoof" design engineering! Took me right back 50 years ago when I was an Austin technical apprentice in Longbridge. My tutors then, would have been proud of your innovation, I'm sure. It's been really enjoyable to watch and understand your thought processes. 👌👌👌

I must say WELL DONE young man ! you just made a bunch of money although you didn't get paid yet.... if you went out and bought that thing it would set you back many many paychecks ! and you wouldn't have it for tomorrows line boring job ! and the best part is you made it yourself and that is quite an accomplishment ! if any thing brakes you can fix it! and that makes it even more valuable to you ! no waiting for parts ! without a doubt this is a victory on a huge scale... in the months to come you will find new improvements that it needs and be able to make them too ! Congratulations to a job well done !

[@donmathias1705]

I made my own line boring setup. Not as flash as yours. I use the boring bar to drive the lead screw. I have a 10:1 self made in line reduction box on end opposite the drive. I have three different screwed bronze nuts it drives. It winds along matching screwed rod for different feed rate. To Travis back I simply drive the the screwed rod faster than boring bar in same direction with my impact driver. If I lock the screwed rod to slop it turning it feeds. Unlock it and it goes nowhere. I've got single phase unit about 1hp geared down via couple of double reduction gearboxes and it runs at about 15 to 85 rom.via variable speed control. Works a treat up. The motor unit and controller doubles as drive unit for my rotary welding table. These than $2000 for everything for boring bar and rotary table plus a heap time. Paid for itself on first welding job!

[@darkfibres]

Thanks for the video! I like how you have shown more-or-less a complete how-to on making this bit of semi-portable machinery, and showing your approach to the design. All your videos are pretty insightful, showing a way to tackle problems when they present themselves. I guess we'll know how well it works after you've had the time to film-edit-post the next video :) The wobble in the leadscrew has me slightly worried, but if it doesn't affect the centricity of the drill it may just work alright. *finger crossed* Keep the videos coming! I'll enjoy them at whatever rate you produce them. (Just an arm-chair machinist here: a second key for the 4-jaw may make adjusting it a bit faster, as you can work opposite jaws simultaneously, fastening one while loosening the other.)

[@larryskeeper1197]

Great video content and editing. Just flows along nicely with an honest commentary. I'll be watching out for more of your projects, thanks .....

[@mfx1]

If the runout in the leadscrew causes excess nut wear then you can let the nut float slightly radially in the hole as it's clamped but yes it is annoying when you think you've been so careful.

Hi: Excellent videos. The last 22 years of my working life work in a multinational repairing and adjusting machining machinery, so my knowledge in that spatiality is enough. Now I am retired since 2010 for occupational disease. The threaded spindle revolves in a decentralized way, it is because of several things, but the main one is that the bronze or brass nut has to thread internally and then mechanize the exterior coiled in its axis in turn placed in the lathe, that is The way to do it correctly so that there is no problem, it can also be caused because the thread of the spindle has been made in 2 ways being the manual that perhaps carved the thread erroneously. Kind regards.

This is impressive work for one who is 'not a machinist' 😁 Remember, the tapping size of a metric thread is the thread diameter minus the pitch.

Excellent. 3 jaw chucks have their place. Apprentices (or whatever) should not be allowed near them until full mastery of the 4 jaw is achieved. It doesn't take long to learn. That and sharpening drills are 2 of the core skills that are essential. Along with being able to make a good cuppa.

[@DavidSellars-b8l]

When burning the heavy plate on the pantograph, you may find it best to drill a starting hole in the plate. Starting at the edge will usually result in heat distortion that can make the part unusable. I'm also thinking that backing off the fuel gas a bit after you get going might be in order.

[@jamest.5001]

It would be cool if tgey made 4jaw chucks with motors to keep the jaws centered when neededto be center, like have a center button avd open a certain percentage, then a close center button so it closes center in the part, then just required a runout test and tightet completely, it would save a tone of time in production, but CNC is for production i guess!

Yeah man! that should work fairly well me thinks. Feed screw seems a bit too fine from across the ocean, but we shall see. Nevertheless Well done

[@snowballengineering]

What makes you think it might be too fine? I wanted it fine so I could run the auto feed faster. Thanks, see how it does.

[@warrenjones744]

@@snowballengineering In my mind anyway lathes, mills, my portable set up etc... all use fairly course Acme threads with deep wide flanks that carry a load good. You can generate quite a bit of tool pressure even with moderate cuts with a portable line boring rig. Secondly in my mind anyway, fine thread screws for machine tool feeds are too slow on return. Also I think the likelihood of catching a chip and binding up are greater. However, having said that, what you have built may in fact work very well for you and your situation. I am keen to see how it works in practice especially over time. I applaud any man who takes it upon himself to build his tools. Cheers

[@FrenziedFruitcake]

Tap drill size for 60 deg threads will be: Major dia - Pitch. So M24x1.5 = 24 - 1.5 = 22.5mm This will produce a hole with 77% of thread which is close to the recommended 75% thread value. However you can go down to around 60% thread hole without losing too much strength, for a M24x1.5 that would be a 22.8mm Drill I only do this with tough to tap materials such as stainless. The formula above works for 99% of applications.

[@snowballengineering]

Interesting to know. Thanks for the info.

[@ordinarymiracles5959]

Do you need to allow for the deflection in the holder where you have an open split in the end that can be clamped , and deflect (?) the rods and accuracy? Thanks.

[@sjv6598]

Superb job on that buddy! Took a little time but you’ve saved yourself an absolute fortune over buying one. With the jerky at slow speeds you could always buy a better quality power feed further down the line?

[@snowballengineering]

Thanks! Definitely saved some money! The jerky slow speed isn’t really an issue as it’s way slower than what you’d ever use it at.

I admire the work. It turned out amazing. Is it possible to order a mechanical part from you? Thank you.

[@Mark-ii2kb]

Don't forget to put the gap back in.

[@mfx1]

You didn't have to spend that much time centring the bronze stock in the 4 jaw as you were both boring it and turning down the OD so it would have ended up concentric even if there was small amount of runout, good for practice though if you've got the time. Also you can use an inverted cone centre to roughly centre round bar in a 4 jaw before doing final alignment.

[@snowballengineering]

I know I don’t need to but like you say, it’s good practice. Takes a bit of remembering which to tighten and loosen. Thanks for that info, I’ll have a look into an inverted cone centre.
