Hello Nate, it¡¯s connected really to my other thread for recommendations for stepper motors, controllers etc.
?
I would like to make some brass flanges and adapters for large format shutters and lenses.
?
A large part of endeavours with the tiny U3 is envisaging what would be successful¡ this is all entirely theoretical (and possibly also entirely mad) but I¡¯m thinking of the headstock spindle and main lead screw being driven as slowly as you like with a stepper motor(s) in the correct ratio, and a single point thread cutter doing the work, spinning away on the auxiliary motor mounted on the slide.
?
I just can¡¯t see a standard cutter scraping away being remotely successful, although maybe I am wrong. The largest thread would be a Whitworth at 12TPI.
?
At the moment it is - as they used to say about futuristic cars - just a ¡®concept¡¯.
?
I¡¯ll have a look for those books - thanks.
