Thanks for the help so far.
Applied Motion Products HT34 series but not quite sure of the size/model. It's one my brother is purchasing used and he's asked me for some help. He runs a decent small machine shop and fabricating operation. His customer needs some help with a conveyor. He recently purchased a CNC plasma cutter - that includes stepper motors. He visited the place where the CNC cutter was made and the owner/designer enlightened him a bit on the virtues of stepper motors.
I am delighted because he comes to me for help - the perfect excuse to go work with him, get dirty, make chips, etc. He'll get compensated for the time and some materials. I get to play, learn, etc.
