If you have a beefy lathe I see no problem doing it like that. With my mini-lathe I almost have to shorten the cutting lenght by using the cross compound (cutting one side instead of cutting the whole "V")
As I replied to David Waller, that is easier said than done. Won't work with the tooling & toolpost I'm using here. In any case, the Ainjest attachment lets me thread at any speed I want towards the chuck. Without it, I'd be looking for different tooling to thread in reverse. Maybe a threadcutting boring bar on the back side of the work...
Offsetting the compound is much over rated for all but really coarse threads. I have conducted tests cutting M12 threads on 303 using the same insert going in radially and with flank and even under a microscope you could not tell the difference. So why move the compound from its natural and most useful position? Have you seen a "clapper box" threading tool?
@@MidEngineering looks like we found each other😉 Somewhere down my videos is my version of the victorian original, not for all occasions but very useful when you can't realistically disengage the half nuts, oh can instantly reverse the lathe. PS thanks for the sub, just about to do the same to you.
@@MidEngineering i hear of something "novel" that might help and give it a go. Some time served chappies will not do anything their apprentice master didn't teach them, i like to play, sorry, experiment.
@@chrisstephens6673 Try this. No "clapper" (tool disengage thing)use the wheel and disengage the half nut. No reversing the spindle, cut threads 3/4 of the way and finish with a die nut. In thirty years I've never got a die nut to start straight, tried every approach. If there split dies you can adjust them for tight or loose threads. js
👍 thanks
I too thread without using the compound, never had an issue either, thank you for posting this video.
Thank you for teaching me to make threads.. success for you

how does the carriage stop work?- is there a clutch in the carriage to keep it from damage?
The Ainjest attachment has its own half nut & a trip lever disengages it from the lead screw when it hits an adjustable stop.
@@MidEngineering thanks for the info
If you want to go faster, reverse spindle, flip cutter upside down and feed outwards.

The only clapper box I know of is on a shaper!

Blue chips nikal raha ha ap ka
Screw away from the headstock, lathe in reverse, tool upside down, easy peasy
Err, no! See my replies to previous comments saying the same thing...
