I think you just move one or the other gear in or out using a smaller gear or a spacer so the line up. It's been at least 43 years since I used a lathe without a feedbox. Glen Here's a discussion on

Hi guys! I've got the gear locations for screw-cutting figured out (stud is topmost, just in front of the two little gears, the comp is next lowest, and the screw is bottom-right, attached to the

For many years I used to take a scratch run on the part and check it with a thread pitch gage, the DRO method (In this case the dial indicator method, but not a dial test indicator) works as well and

Thanks, Glen !? I'll give that a try and report back with my findings.

Sorry for the misunderstanding, DW.

The last time I tried to set up the old style gearing I gave up without a struggle, just because a feed box makes it so easy that it's part of my understanding of the lathe. One of the questions I

I ask because I’ve the same question! John Rosberg

I'm backing out, intended no snark.

Hi John! No, not yet. I just need to know exactly which gear is which on the gears, as listed on the back plate. Thanks!

I'm a certified machinist, but it's been about 6 years, and several hospitalizations at the VA, since I've done anything in my machine shop.? I'm not asking how to cut threads, just how to cut them

Did you ever get your stud gear question answered? John Rosberg

So you still think you know what size he wants to make an internal thread in, or what hand? BTW, I only saw one 1 1/4 - 20 tap for $25.50 tap and with shipping it's $39.40, maybe he isn't rich enough

And if it's a size that no taps are made for what would he ask himself? Taps are almost always available. To use your example, there are at least a dozen online sources of 1 1/4-20 taps.

I'm curious DW, how did you know what size hole he wanted to produce threads in? He may have been wanting to make an internal hole inside a telescope eyepiece mount, or to get higher quality

I'm curious DW, how did you knew the internal diameter is small enough that a tap is made for it? If he's making a telescope eyepiece fitting it may be 1.25 X 20 TPI, but he didn't say, or, he may be

By the time you have succeeded, and I have no doubt that you will,you will have revisited the question of why you didn't use a tap.

Thank you, Glen! Yes, I'm all set, except for how to put on gears.? I just need to know which gear is the stud, which gear is the screw.? I'm doing a 20 tpi internal thread.

I apologize Joseph, when I saw your email last night searching for a youtube video that would cover it and found four that didn't cover them, and intended to continue however I was exhausted after two
