All the belt suppliers like Gates, have web sites with engineering data.
If you know your requirements (torque, power rpm) then yo add a safety
factor of about 2.5 then select the parts. If you do this then with either
belt type you should be able to stall your motor.

Actually drilling the timing belt is not a bad idea. The older MXL type
belts used a trapezoid tooth belt but the new high torque "HTD" Designs use
circular profile teeth.They really are bater and transmit more torque
with less belt tension required. Even newer designs are GT2 and GT3 and

I don't know if you can, but my hob is for T5.

I'm surprised you can cut XL pulleys with a hob. It does not look like
the teeth are right for that to work.If I had to make an XL pulley from
scratch, I'd guess the best way would be to use a 4-axis machine and a
ball-end mill. That is one reason I'm wanting to add a motor to my rotary

You could send a drawing, but I think that my turnaround time would be a
problem as I am in Turkey until the weekend

I always buy my pulleys with undersize bores and bore them
out. Stock sintered pulleys

Check this place out Gene,
http://www.hmmanufacturing.com/pulley-stock1.html
I just bought some stuff from there, good quality, great price. We have
a situation on our edm machine where the standard sheaves available
weren't wide enough, and I found these guys.
Hope it helps,

Greetings all;
Do any of you know of a pulley maker that can supply a large hub in in a
40 tooth pulley that is also more than an inch wide at the hub?
I find that to align a belt on the X drive, that I have to find a pulley
with an 8mm bore, but around 2" wide at the hub, because I am going
