I found that belt earlier today, someplace else at about a 4 dollar bill. Polyester back if that means much. That one could be used if I set the motor father away than I had in mind. If my belt length calcs are full of it. I imagine there is a formula for unequal pulley sizes but I haven't found that one yet either. But I think, before I even dismount that part from the chuck, that I had better find one of those toy psu's they use in the atom powered ARK boxes. Thanks Todd. I may yell at the folks who had it in the $4 range tomorrow and see if they can go a bit shorter. But tonight, I am about used up. > ----- Original Message ----- > From: "Gene Heskett" <ghesk...@wdtv.com> > To: emc-users@lists.sourceforge.net > Sent: Thursday, April 30, 2015 2:16:55 PM > Subject: [Emc-users] micro-v belts, smaller > > Greetings all; > > I have been snooping around with my google-fu, and coming up a bit > long. > > Long as in the smallest of tese belts with a kevlar backing, is a 3/8" > wide 3 ribber, 21" long.
