this is just awesome , why isn't anybody making movies like this anymore , people used to really cared about making educational content
I run a lathe that's over 100 years old. This is the perfect guide to anyone needing the more subtle cut of HSS rather than aggressive carbide.
Mine is a 1944 Logan used in war production.
A great historical video and informative. As a manual Machinist myself (using no Digital read outs) only the wheel to put on cut and mic's and old school knowledge passed down. Thanks for sharing with love from England. Proud to be a turner.
CNC guy trying to grasp the basics. I've taken it all for granted.. throwing carbide insert tools into the turret and running the program. Now I'm trying to run a manual lathe at home and realizing I don't know shit.
Those are some massive cuts. No C's and 9s here. Thanks for posting this and passing on knowledge so many have left behind.
A1, 1st class, no gimmicks just plain good teaching and easy to understand.
thanks Colin UK.
It is the men who have made our machine age possible.
Are we in a machine age?
Very cool, simple and to the point
more guys need to watch this, if anything so they can learn to make thier tool chip correctly. I've seen guys with 6 foot scrollings whipping all around them! that shits sharp and hurts. not to mention hot! and the chance of it getting caught back in the works.
Thanks for the video, beautifully straightforward
Excellent, it might be an old video, but it's still true today.
Love these old films....they remind me of my youth when films were jumpin' all over the screen!
its fine when its film jumping but i really despise this modern filming technique of bouncing around all over the place. somehow its meant to convey "action", i think it just conveys nausea...
That was so informative, thanks.
Good work guys
nice explanation
Thought this was one of those old films put out by South Bend but that certainly wasn't a South Bend lathe shown at about 10:00!
had to replay that first bit before i got it...
"special steel", NOT "stainless steel"...
was worried that they messed up in teh first few seconds. that would have been a concern...
i've been looking on tool bit formulas since I forgot about it because i'm dumb, can anyone show me how to create an edge on the toolbit? I remebered that it's between 45 degree and 35 degree but it depends on the size of the toolbit because last I did it in college was I brought a huge ass toolbit and my instructor told me why did I not buy a normal one? well, I just realized it when I was going to his class so I just bought whatever I saw and hurriedly go to his class, I remembered my rake angle was around 30 degrees or something
No big trick. You need clearance angles on every face that touches the work. a few degrees works 5-10deg. The top is just a matter of how the metal will react, brass requires 0 degrees. Steel , aluminum etc will still work at 0deg but cut more easily with 5-15degrees sloping away from the cutting edge. The most important thing is clearance so the tool does not rub, after that is is the top just steering the chip away.
Can you give me The video complete Please
thanks grandaddy
What? Why?
That's a hell of a fuckin' chip.
How sad is it that I have one of those lathes in my shop....
Randy McManus Why is that sad? I think it is great preserving a machine that has a history and story to tell.
+Randy McManus I will take it if you don't like it :)
I have thought about selling it from time to time

You'd better tell Zorgoban- he has first dubbs. LOL
I'm living in Europe. Depends on the total cost. If it's in good shape it's probably still a nice machine for a hobbyist like me.
