Source for timing pulleys
Hey guys, I just got my MotionKing steppers in today, and was trying to find a reasonable source for pulleys to build my belt reduction. The MK motors have a 14mm shaft. I want to go either 3:1 or 4:1 on reduction (still debating). After searching for some time (all afternoon), I have struck out in finding 14mm bore timing pulleys. Any suggestions for a US source for these critters?

I gave up too and ended up using 10mm i/d pulleys and resigning myself to drilling them out.

I used 15 tooth XL and bore it for 14mm shaft, my motor had a keyway so I made a passage in pulley 2.5mm for the key on the mill also. and it did not break.
It works ok. |

Thanks guys, it looks like I'll follow suit and bore the hole out to fit.
Mike, I appreciate the link and part #'s. I looked on thier site yesterday, but didn't see any 14mm bores, so I didn't pursue things very deeply. I'll order these this week, and get my reductions built. |
