Hi all; For want of a better project to keep me out of the bars tonight, I went out and extracted the stripped belt off the toy lathe just now, find it well labeled as a 130XL037, 3/8" wide, 65 tooth belt. It appears that I had already replaced the ultra teeny drive pulley that stripped the last belt easily had already been replaced with a 15 tooth model. So even with about 7 cogs fully engaged, this motor still had the cojones to strip the teeth off the belt. So I am thinking out ordering a 140 or even a 150 (75 cogs) belt and a bigger lower drive pulley which should get more cogs engaged. That will of course raise the spindle speed and probably make me run on low backgear more often, but this motor has the cojones to do that so I am not worried too much.
So my question is, if I buy a 150 cog belt, and the existing lower pulley has 16 cogs now, and I add 10 more to the belt, making it 75 it sounds as if I would need to add another 5 to the almost half circle that would be engaging the belt on each side, so the 16 cog pulley now would turn into a 26 if I want the center to center distance to remain within say 2mm's of what it is now. That seems to me like if I tension it to about high C, that ought to be able to survive that 1 hp motor long enough to at least finish one job, bearing in mind there is a 3/1 stepdown between the motor, and the shaft turning this lower pulley. Is my math somewhere near correct? And would I be better off paying the price of one of the white poly/kevlar belts as opposed to this black one with a few strabds of kevlar in the backing and teeth that look like a glass reenforced black rubber? I'll check McMaster-Carr, but I can get this belt for about $4/copy from the prople that used to be GoodYear. Comments anybody? Or did my mental math blow it, like its been known to do several times before? Cheers, Gene Heskett -- "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
