For small threads, I do like Zee mentions, hold the tommy bar in one hole on the die holder, and clamp/release the headstock with the other hand.

What do you mean clamp/release the headstock? I just turn it. (The chuck.)Let's say I have some rod in the chuck that I'm going to thread.Die holder goes onto the tailstock.Start threading...Whether I turn the die holder or the chuck...what's the difference?Now I have a mini-lathe. I can wrap my hand around the chuck...basically turning it like a die holder.Hm...I don't even know how to clamp the headstock.Confused. And it's not even stinking hoppie time.
On my chuck, it is easier (for me at least) to hold the chuck/part in the headstock with left hand (what I meant by 'clamp'), turn the die holder with tommy bar in right hand, then let go with left hand, pull tommy bar back with right hand to starting position, and repeat.
Yes I'm still watching you from the shadows
I knurled my die holder and I'm able to run all but the larger threads while holding it by hand. The knurls are not sharp and when I let go and it spins in my hand, it doesn't seem to remove any skin.
I find this tool very useful, may take some adapting for youre lathe but well worth the timehttp://www.hemingwaykits.com/acatalog/Spindle_Driving_Handle___Myford_Lathes.htmlIt works on the same idea as a rawl bolt
Its is just an expanding mandrel with a pin that make it self releasing although thats just a luxuryThats the advantage of been sinister handed Well worth the effort making one I use it often for threading
When Vati saw me do stuff like that he would mutter something that sounded a lot like, "Schusselig Stümper". Maybe we need a new Post-It - Sei nicht Schusselig".
