Cool video... Just wondering, why did you make it out of 304 stainless? Wouldn't 4140 or similar be a better choice? I don't have any of my material handbooks handy, but I would think that 4140 would offer better wear and vibration resistance.
Does that lathe not have a taper attachment?
Like I said, just wondering... Not trying to give you a hard time.
Are you a machinist or is this just a hobby for you?
The lathe has no taper attachment. 304 stainless is strong, it machines exceptionally well, and it maintains a beautiful appearance,(no rust). 4140 doesn't machine anything like stainless.
Right on. I was just wondering, partly because I don't like machining stainless... Too stringy and gummy... Unless it's 410, then you can break a chip nicely.
@EruditeCanadian If you use carbide tooling , keep the surface speed high, use lubricant, and keep the work from getting hot, then stainless machines beautifully. 17ph4 is a bit more difficult but I can achieve the same results as well.
Yeah, I've worked with 17-4 a bit, and a fair amount of 410. I don't mind the 410 because it likes to break a chip nicely. They use it a lot in the oil and gas industry here in Alberta.
I once machined an impeller shaft out of 410. It was about 6 feet long X 6" diameter. It was a pretty cool job, a couple of bearing fits, couple of threads for Timken nuts, couple keyways... It was one of those jobs that makes you feel good that you're a machinist, you know?
Yeah, most of the work in Alberta is based around natural resources like mining and oil/gas. So, a lot of the work is really big. At that same shop, we used to repair track idlers for the Terex RH400 facing shovels they use in the oil sands mines. They were about 6 feet dia. and weighed 7 tons! That's too big for me though! Check out Fort McMurray oil sands.
I wish I had taken some videos of that place.. I could have posted them like you!
@tschaeikaei3 Water soluble oil coolant is good. You need to have a sharp tool with a small point so that there is no vibration. Positive rake tooling is better too.
My tool has a TiN coated carbide insert with a 5* negative rake angle and a ,2mm cutting point radius . The spindle speed is 1280 RPM
@newcomer9747 No, I don't have the manual. I also had some electrical problems with carbon tracks between the contacts on the switch and called Leblond about it. The switch is no longer available. I have removed several of the contacts on the original switch and I have installed a standard drum switch for reverse.
Thanks! and you're right. This one was new in 1955. The bearings were changed in the headstock and I changed the cross slide screw a year ago. It is a 13"X40"
sometimes Stainless steel is wierd and difficult and it presents a challenge. but looks excellent when it's done and makes you proud of your work. Well done!
The video clearly shows the drill in its adapter, in the tailstock of the lathe, in the last picture. It is a large drill, maybe that's what you noticed. :)
I Love the Moody Blues track playing in the background

@ytmachx np. I envy your lathe. I only have a bench lathe (atlas) right now. Gotta' get me a nice engine lathe (maybe a 13X36").
This is just the kind of project I would do. Just finished making a t-handle securing screw for my old drill press on the lathe.

Hey, i tried to machine an adapter MT3 to MT1 on my lathe.
I used stainless 304 too. But I got a creepy surface.
Is it a bad Idea to use coolant?
(I have oil-water mixture, not shure how you call it in the US)
I did it with some HSS-tools and tried HM too.
Nothing really worked.
Thanks for your answer and cool video.

Damn I have the same lathe! Sadly it's sitting here, has some problems hvnt got around to fixing it. Do you have a manual or electrical diagram?

@ytmachx nice work. now i have someone to refer to if i ever get to fixing that lathe lol.
