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.

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

You do realise that you are a true old school engineer and all these new so called cnc students don't have a clue what skills you have.

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.

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. 👌👌👌

that is a great tool you made

Really like this idea

Excellent now you have another proper tool for the job.

This is well built. Will last for a lot of work.

I like your work.

Nicely done! Looks really nic and vil work well! 🇳🇴

Gday, the unit turned out spot on, I think it’ll work no worries at all, top job mate, cheers

Great work making and putting all the various pieces together to make it happen. Can’t wait to see it in action. Take care and good luck

That looks pretty awesome 👍

No need to apologise, work comes first fella as it pays the bills (and it’s not like they get any cheaper) and really appreciate and enjoy your content/editing time permitting 👍 Great bit of workmanship and it’s turned out great, proper bit of Agricultural Engineering (built to last 😝) Its great you show the errors/mistakes/school boy errors etc, my old man told me “ a bloke who don’t make a mistake doesn’t do a great deal in life!” So I guess I must get loads done 😂🤣😂

Thats an amazing job, it will be nice to see it working on your projects. Thank you posting

Really enjoyed the process from start to finish brilliant. Looking forward to seeing it in action for the first time. 👍👍

Great job. We shared this video (alongside the previous parts) on our homemade tools forum this week 😎

loved the build series, cant wait to see it working.

Absolutely brilliant video

It's been really interesting to follow the making of this tool , impressive stuff , thanks for making the effort to show us the process.

Great info man, thanks...

I love the heavy engineering of it, reminds me of something my granddad would of made. Great video as usual 😊

Really nice bit of home built kit! It should do a really good job , I hope it’s a cash generator for you! Cheers!

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

Nice build and shows just how clever you are.

nice work you should be well pleased with your effort thanks for posting

Amazing. I'm not a machinist, but to watch you doin your thing , and overcoming problems , is fascinating. Bloody well done 👏. I'm sure it will work fine. Even if it doesn't, I'd put that machine on me Mantlepiece. 👍👍👌👌👌.

That's some amazing engineering work. Great work and video

Can't wait to see it in action 😃

Really good bit of kit, well done. Necessity is the mother of invention, a good saying when you want to push yourself out of your comfort zone. Be safe keep well.

Very satisfying sound when you cut the ‘tacks’ on the ‘slit cut’. This is a great series. The other big RU-vidr I am going to mention you in the comments is ‘This Old Tony’, what an awesome channel he has. Kindest regards from Bonnie Scotland. (Uk) Joe.

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.

Love ❤ your choices of backing music 🎵🎶 6th night of binge watching 🤓 👍🇬🇧

Congratulations 💐💐🎉🎉 to you great content keep up the great work. I enjoy your content look forward to seeing your next project.

That is a cracking little machine!!! Nicely done 😊👍👍👍👍👍

Amazing job, well done!

Beautiful job. Glad it came together

Hi, always nice to see what you do for a hobby,mines is collecting Diecast model trucks, love the Fergie regards 🚜

Need a small horizontal boring mill for making some of these parts. Love your channel.

That is a very clever bit of kit, and well done. Would be pleased to contribute toward additional tooling (boring head, etc) as I’m sure others would as well 👍🏻

Labour of love! You will get lots of use out of this machine it's a good as a "bought one"!

Very nice piece of kit you've made there, it'll more than pay for all the effort within a few jobs I'm sure. Great content and straightforward videos

Excellent build. I have thoroughly enjoyed watching the build! Cheers from Australia 🇦🇺!

I use a digital caliper when translating measurements. Easy button push between the two. Great video. Impressive shop and knowledge. Keep it up

💥the snow borer 3000 is ready for work 😀 it looks good . Thanks for the video s and look forward to seeing it working 👍

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.

I’m wondering if it would be worthwhile to thread your center hole of the wide clamp to allow for opening it rather than prying it apart. Good vids! Thanks!

Sometimes it’s better to be lucky than good.

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.

Fantastic build👌👌👌its gonna work perfect👍

Thumbs up from me!

love you content. keep up great work. I have got one of these on my list to make. as well thanks for inspiration.

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!

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.)

Nice build on the boring bar. Some lube on the lead screw should help it loosen up.

Nice job again 👍

Nice Work! I greatly enjoy your vids. Keep up the innovative work.

Nice job great video

Nice project ,well done!

Fantastic job

Well done nice work 💪👍

Mate that’s awesome!

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.

Cracking job mate nice work

nice job proud I found your channel

Great project, great video!

It's not just about how it looks sunshine... Cracks propagate from sharp inside corners... Good videos ☹🇬🇧

Good work

Great work as always

Great work...

You can also put a 3 yaw in the 4 jaw

you have the process before you start ... by creation.... the gizmo's will show up as needed ... I can't be more interested in your progress... I am a fan ... I worked at Cameron Iron ...maintenance for 30 years.. I have seen machining countless times

Thanks for the video

Hell yea good job 👏 👍👌🤘🤘🤘🤘

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.

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

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.

Bloody good job mate, been following along with this build, and you're making a cracking job imho, an old engineer taught me, the 2 fastest ways of removing materials are the grinder and saw 👍

Nice job! We did a similar York styled unit. The fine lead screw would be an improvement on ours.

It's been the most interesting thing I've watched for ages nice job well done If you want to shoot me sizes for the bearing retaing washers I'd love to machine them for you from aluminium bar got plenty that came from a skip 😊

I may have missed it but have you listed the drill you used and the the other parts. Great job on the build.

I reckon that will do the job as well as a £15k rig.

WHAT, You have to show us it working!

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?

Moin, sagt man im Norden von Old Germany, Kollege ich bewundere deine Arbeit, geht nicht, gibt's nicht bei Dir, bitte mach noch mehr so schöne Projekte. Übrigens deine Frage Pulverbeschichten oder Lackieren ??? I sehe es bei uns immer wieder das bei der Beschichtung irgendwann sich unter der Beschichtung Rost bildet, für mich kommt da nur Hammerschlag Lack in Frage. Ich wünsche dir weiterhin viel Erfolg und Spaß bei deiner Arbeit Grüße aus Lübeck Germany Horst.

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.

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.

Nice work another tool for the shop. Out of curiosity if you don't mind me asking do you own the shop or do you work for someone?

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

What a cracking job mate, you should be well pleased with it. Have you a rough idea of the cost ?

Nice job, do you fire up the radial drill in the background?

Hi you can always grip your 3 jaw in your 4 jaw if you want to do some repeat turning .

👍👍

What is the power of the drill?

Hi What model and brand of drill did you use ?

Why is a line borer so expensive? It only takes 3 hours to make.

Либо монуал этого сверлильного станка а то достался бесплатно
