Learned alot about threading yesterday:
Not looking too sweet. (Sorry about the focus! Threads were forming, but there is alot of tearing that is hard to make out. Fingerprints look great though. Lol.)
I'm thinking I was taking too much material each pass, not certain, but I also wanted to clarify:
(I was using the "never disengage the half nut" technique)
When initially starting a second pass, the proper way of feeding the cross slide is to start the lathe, then feed the cutter into the material to the proper depth, or is it okay to take up the backlash, stop the machine, feed in 0.002 (or w/e) and then start the machine?
I'm also unsure about what speed a threading operation should be done at?
(I was working on the slowest to best reduce the odds of crashing my lathe!)
It seems to me that cutting faster will help improve the finish, but increase odds of a newb mistake.
Any Tips?
Side note, I spent hours getting the above (captive nut) prepared to match a coupling nut I picked up at my local big box, got it to the above state, and realized that I spent all that effort just to thread the bar 1 tpi too many!!
(Must have grabbed the wrong change gear earlier)
And as such, have picked out an empty drawer on my work bench for "failed projects"
