- Creating a boring bar for our line boring jig on the clausing lathe. We demo the making of the bar and how the jig is set up to machine bores on items that are to big to just bore in our milling machines. Part one, intro to project and starting the machine work for the boring bar itself.

Forget the noise...what you brought to us in thoughts and techniques is priceless! Thanks, Keith! ~PJ
Boring out to .625, using a half inch bar. That groove/flat, ripper, made a helluva difference. Dave Wilks his trepanning tools have the same relief for the chips.😊
Keith I echo all the good points that viewers have put forward. Excellent video's so keep em coming as they are. regards from the UK
I'm so glad you put this back up. I was so glad you mentioned where you bought them and what the inserts were called. A few months ago when i made my first line boring bar i could not find these anywhere. Ended up crudely milling a square hole with rounded corners and ground down the corners of the bits... it worked but not very elegantly. I posted a few video's if you want a laugh
Thanks again
Just glad to be seeing more from Turnwright :) Cheers Keith
Hi Keith, you should know by now to ignore the nit-pickers. It's always the content that matters, not minutiae of sound quality, You tube doesn't need BBC quality production values to wow dis-interested viewers because all who watch you are dedicated fans already.
The audio is fine and your work is incredibly interesting!
thanks for sharing. i'll about to make a boring bar set up similar to this but in a hobby sized. thanks for the tips.
Machine Noise? That's part of using machines. It's part of how you tell your machines are running right or not. I'm watching these videos to learn about machines and machining and part of it IS the noise! What the tool sounds like when your using say a flycutter. I want to see AND hear it. I never had any issue hearing what you were saying. Keith your videos are great, keep them coming please. Waiting see No. 3

Brilliant
still another very good video. no complaints here ,,,,,
thanks for sharing,,,,,
top job , as always !!!
Real machinist,after years in a shop are already used to noise or can't hear. So don't worry about mic noise.
Newbie,wannabe,critics this hearing thing is something to look forward to.
Critics need not apply.
Excellent old school technique,,, and lookin' great,,, Thank you Keith! :o)
O,,,
Dang :-)
I thought you were going to recommend a fine vintner's establishment in which to socialise on my next holiday to the Cape :-)
Thank you very much
I went to a boring bar once. It got more interesting after a couple of bourbons...
Watching this the second time I just noticed how shiny that mill vise handle is! I have yet to figure away to get decent footage when my mill is running, it just makes too much noise.
Hi Keith I have several boring bars that are not shop made and they all have the tool drilled in the center of the boring bar and most of my have a Morse # 4 taper for my HBM
THE IRONWORKER Yes a lot of bigger bars made for the HBM's and such, using Morse tapers, where the direction may be necessary to run in both directions they were put on center. ;{)------
Hi Keith,
again, many thanks for allowing us a view over your shoulder. learned a little something new in this episode on how to correctly position the tool bit in the bar.
got two questions:
1. what size of spout do you recommend for the coolant? i have a fairly small one on my bridgeport, 1/4" was pipe fitting diameter. the thing really spits the coolant out inspite of using the petcock to regulate flow. it burps pretty violently when i turn on the pump and spits a big bubble and splatters it all over.. it was a cheapy off of ebay, most likely made by our friends from unfinished tooling in a land far away...
2. when you run out the cut to make your taper, would it be easier for a beginner to use the power quill feed? i realize your K&T doesn't have a power quill feed, in that instance you would probably have to use the power feed for the knee.
cheers,
mike
HolzMichel Most of the times when you order the coolant flex lines several nozzles come with it, my experience of try a few and find out what suits the job, flooding the area or using the force of coolant to flush out the chips, when needed. you can rid of most of the air burps and surges with the start up on your coolants using or cleaning a check valve in the feed line, which holds the coolant from flow backs to the sump. I also raise up the spout to put it out of my way when not using it and that keeps some in the line near the exit. most of the time you are going to get somewhat of a spit out on start up but in between part changes or direction start and stops it mellows out with check valves. ;{)-----
Keith, in your spare time, why don't you build a custom adjustable speed feed attachment on the KT to raise and lower the table? Automatic ramping as example.
Yes, I know, pie in the sky. But we know you could do it.
What type of oil do you use for brushing on the drills?
Hi, which type of steel is the boring bar made of? Thanks
What is the MSE book?

Reliked your reuploaded video's. you deserve it. Thanks.
For a import anyway. lmao
You lost me when you left your machine running "unattended".
what's with peoples obsessions with making things about gender? I love ya Keith, but is it really necessary to make a weird sexist comment when you could just say "I really like bronze"?
