We take a look at the Unimat SL1000 / DB200 lathe screw or thread cutting attachment. I explain fitting and how to use and operate the attachment both manually by hand and under power using the slow speed pulley bracket.
Ah the memories. That was the first lathe I ever used. My dad bought it when I was 8 years old. Never had the power feed or threading attachment though.
This works like the threading attachment on a Hardridge tool room lathe. On the Hardridge the master mounts on the outboard end of the lathe spindle. This makes changing thread pitches about a one minute job.
Wow. As I started watching this I thought "I wish I had that attachment for my SL" but by the end I figured I'll keep cutting threads on my 13" lathe. That's pretty close to more trouble than it's worth.😁
THANKS for the demo!!! I always wanted to see it in action! That is a MINT accessory which must have cost quite a bit!!! I think only a collector could love it though!
Great video Matt, very interesting, your Unimat SL is certainly in excellent condition. I have a thread-cutting attachment for mine but have, to date, never needed to use it. You have inspired me to give it a go. :-)) cheers Paul
Good video and a cool attachment. I have a much better understanding of how the master/follower now works. It looks like it does take a while to set up properly, but once set is pretty easy to use. Thanks for posting this! very Instructional.
It's a decent designed lathe but it's just too small. If it was twice as big, it would make it easier to work with. Regarding the return spring, I'd just take it off.
