I am new to machining and don't have a lot of experience. I'm using my Harbour Frieght mini lathe to make a spring plunger that is used on the Savage 10-ML muzzleloader.
I can do most any of the lathe's functions fairly well except cutting threads. I have the timing down (I think) and the gear selection but the threads I cut come out a bit rough. I thought it might be my HSS tool I crafted from a block but the purchase of a turning set that had a 60 degree tool as a part of the package didn't help. I believe I've centered the tooling properly but other than that can't say I know proper set up.
Do you mind giving a novice some hints on how, what, and why of cutting smooth threads on a mini lathe? I shoud say the threads I'm cutting are 1/4 28 common screw threads. |
