Hi
I've finally go back to building the hot wire cutter but I'm struggling to get the lead screws which are M10x1.5 thread rod connected to my stepper motors. I basically need to get one end turned down to 1/4" to match the motors. Does anyone know of anybody in the Rotherham area with a lathe that can do this. I don't mind paying for it as long as its reasonable
you could always look in the yellow pages

you can buy couplers with different sized ends, if the ballscrew has a turned diameter already.
Sounds like it's threaded rod not ballscrew. Either way I could do it, but I'm quite far away...could post it I suppose. Probably cheaper for me to buy the threaded rod (about £5/m for M10 stainless), machine it and post.Quote:

it does sound that way..:smile:
you could thread the coupler to suit the leadscrew.
True, but the thread needs to be nicely on centre...Quote:

it will, all this depends on what he has available. It's easy for us with plenty of gear to suggest options.
Might be an idea to take a look down a nearby industrial estate for a machine shop to sort this.
