Re: [CAD_CAM_EDM_DRO] What pulleys and timing belts do I buy from sdp-si???

Peter,

I will try and work on my belt reduction document. I believe that I sent you
a picture of the drawing that I did in my Alibre program. I used aluminum
pulleys and a 3/8" belt. I can give you the SDP-SI part numbers. My
reduction was 3.2:1 which worked very well on the ShopBot router.
