Re: Does anyone make new thread guides for the db /sl?

I am not going to call an Atlas lathe modern, but the threading chart I just looked at lists 27tpi as a regular thread. I have a need to cut 30tpi threads, and I'm going to need a 2nd 32-tooth gear for it. 3D printed one, can't wait to test and find out! At one time, I also wanted to do a 25tpi thread. Don't recall exactly why, now. That one is not on the chart. Going to have to dig through my threading supplement to see if it has a setup for that one, in case I remember why I wanted it. ;)
Anyone want to send me drawings for the parts needed to do 27tpi threading??

I'm not sure it would be easy to set up many modern lathes to cut 27 tpi. Not sure about some of the older ones either. I'll have a look at our old (1950s vintage) Cardiff to see if that can do it, and how much hassle it would be.
