Re: Long Acme threaded rod

Hello,

I've considered various means of providing movement and I prefer rack and pinion; the cost is relatively low, any length can be achieved, and as far as I am concerned they are trouble free. If you like I can send you pix of the machine that I made using R & P. (I'll need your email)

Regards,
JCC
