I have a few parts to make that are about as simple as it gets. But the problem is that they are made from 6061 and the finish diameter is .255 +-.001 and a length of 1.950". So I'll have to start with 3/8" round and by the time I allow for face material and a parting tool, it just seems like that's a lot hanging out there once you get down to the .255". Isn't there kinda of a rule of thumb to use for length vs. diameter before it has to be supported in some way? Since the lathe is new to me any suggestions would be appreciated. I know you could take some light spring passes and, or program in a taper to compensate. Just curious how you guys would do this and what kind of cut depths you would use. Luckily the length dimension isn't real critical.
Thanks!
Thanks!
