Re: Threading for the first time

A wheel is fine for things like collet closers, or to add inertia to the
spindle, or if you like to stop & start the spindle by hand, as is necessary
on a sewing machine, but for threading, you need torque and control, and the
hand crank rules. The radius wants to be 6" at least, and 8" is better.

Thanks, guys... I like the idea of a wheel, but I would think it really
needs a handle to hold onto. One of the linked designs was set up with
both. I'll pick one and go with it. Now if I could just find some 1 1/8
inch round stock without having to pay more for shipping than the metal is
worth! I have one inch in stock, but not 1 1/8 inch...

Well, maybe I'll put together another metal order...

OK, looks like I need to make a hand-crank for the mini-lathe...

Thanks to all for their suggestions and comments!

Hi, All,

I'm going to try single-point threading for the first time. I've read up
on the procedure, and I figure the best way is to just jump in and give it a
try. I'll initially make a 3/8-24 thread, only because it's big enough for
me to really see the progress as it develops. But what I would really like
to make for use after that is a 5 mm thread. These are, I believe, a 0.8 mm
pitch. My goal is to make some thumbscrews to hold the gear cover on my
lathe without having to use a hex key to get it off. My question is whether
this is too fine a thread for me to do as a beginner? Are there any special
tricks?

I guess it really doesn't matter; if I screw it up (pun intended), I'll
just try it again.

Thanks,
Charlie
