who makes 112 GT2 5mm pulley

[AustinT]

Hi,

I recently built a plasma table and am rebuilding it so i can do light carving as well. Currently I am using a 28-72 tooth reduction (2.57) I bought the current pulleys from stock drive. I would like to find a 112-120 tooth pulley in aluminum. Does anybody know of a company that has a pulley ready to go

Specs 112 teeth GT2 5mm 15mm wide

Thanks

Thanks for the reply, That is where I bought the pulleys that I am now using . I am using a 28 pulley on the stepper and a 72 on the shaft with the pinion gear. 72 is the largest pulley stock drive sells in the gt2 5mm. I have found a 112 tooth pulley from the website below but it is steel not aluminum.
Where is everybody else buying pulleys? I would like to stay with the gt2
and get around a 4-1 reduction. The ID bore needs to be .5 on both pulleys
