Re: [CAD_CAM_EDM_DRO] Stepper Pullies

Hi Bill,

Have a look at www.hpc-gears.com and request one of their free catalogues,
It has details of timing pulleys in the technical section - you can see the
type of pulleys in the 'belts and pulleys' section of their web site
although this is still under construction. For the little 2.5mm pitch belts
I used, I just bought one of their commercial pulleys and pulled the side
cheeks off to measure it up. I found that it was made by drilling a circle
of holes and turning almost half of them away, the sharp top edges were then
just rounded over. I made three complete sets and they seem to work just
fine - saved me about 50UKP!
