It's a little bigger than a typical watchmaker's lathe, but there are a few guys who use them as such. <br /><br />One of the model makers decided that the standard sized screws he could use just were wrong for his models, so he developed ways of making things like a .025-300 TPI screws. Made his own dies and then tapped the wire with it. <br /><br />There's a threading set for the Sherline, but I'm concerned that I'll need to do it on this lathe at some point. <br />SiGraybeardhttps://www.blogger.com/profile/00280583031339062059noreply@blogger.comtag:blogger.com,1999:blog-1592992209402300549.post-85720765909032139832018-07-04T11:29:34.167-04:002018-07-04T11:29:34.167-04:00You need to get yourself a watchmakers lathe!

Someday, I'm going to have some obscure part that needs to be threaded on the lathe and it would better to know how to do it than to go find a custom part. <br /><br />Otherwise, I would have already cut off the stud and threaded in a 6-32 screw that I had cut the head off. <br /><br />SiGraybeardhttps://www.blogger.com/profile/00280583031339062059noreply@blogger.comtag:blogger.com,1999:blog-1592992209402300549.post-33120122614062529162018-07-04T10:25:29.039-04:002018-07-04T10:25:29.039-04:00I guess you're doing this just for fun, but th...I guess you're doing this just for fun, but these kinds of parts are usually just something you buy, like screws. I just took a quick gander at McMaster-Carr, and the smallest externally-threaded clevis rod end is 10-32, but somebody somewhere has to make these.Malatropenoreply@blogger.comtag:blogger.com,1999:blog-1592992209402300549.post-62309693668656217852018-07-04T10:03:44.656-04:002018-07-04T10:03:44.656-04:00See what I mean?

You would need to be careful, of course, especially with an item that small, but the started thread should be enough to let you engage to die.Mark Matisnoreply@blogger.comtag:blogger.com,1999:blog-1592992209402300549.post-48804118021756900302018-07-04T08:59:39.639-04:002018-07-04T08:59:39.639-04:00The male cat read this and I've gotta say I...The male cat read this and I've gotta say I've never seen a cat do that with his claws before. <br />SiGraybeardhttps://www.blogger.com/profile/00280583031339062059noreply@blogger.comtag:blogger.com,1999:blog-1592992209402300549.post-68882066073319360542018-07-04T08:57:01.204-04:002018-07-04T08:57:01.204-04:00I made the panels in my mill enclosure out of that...I made the panels in my mill enclosure out of that stuff.

So then I figured the emergency fall back plan was to do exactly what you say. Cut off the stud, drill and tap it, saw the head off a screw and LocTite it into place.
