Building my second steam engine and am having trouble threading a brass rod. Its a 3/32 diameter rod with 3-48 RH thread. I am using a die holder on my Sherline lathe mounted in the tail stock. I cannot seem to get the lead right. I keep striping out the thread. The ID on the die is facing rod. I cannot determine if this is the entry side?? Turning the head stock by hand.Should I try threading by preventing the die rotation while loosely mounted in the tail stock?Thanks for any help.DaveDave Assuming you have tried the things others have suggested, and are using brass rod of material that can be threaded (Not brazing rod or some others) this will be quite common when using dies from China and India. If so, purchase higher quality USA or European. Also, I never really understood the tailstock Die holder thing not that it has anything to do with this issue. I simply place the Die in the chuck on the headstock.Jerry Kieffer
I'm betting on a bad dieYou've got the die facing in the correct direction, opened up, tapered start.I do remember fighting with a Chinese die for about a week. Got a new die from McMaster (it seems that most of what I get from them is USA made.). Cut like butter.I do have Chinese dies that are fine. That one missed it's visit to QC.
