I have a pic here where you can see it.

Lower bolt hole is the pivot, the upper bolt is the slot for adjustment. It has a somewhat narrow adjustment range but with the right size belt you only need it to move a little bit to achieve proper tension.
Haven't blown up a single belt with the new bracket. With the ATI setup with the idler pulley I would get about 400-500 miles of life out of a v-belt before they would start to split badly; first high RPM zing in that condition would result in a grenaded belt.
I still have the CAD drawing of it. You can print it out to scale and use that for a template or CNC it if you want to go that route. Eventually I'll remove mine and lighten it up some with a few speed holes & pockets, it's way beefier than it needs to be. I only made it out of 3/4" aluminum plate because that's what the ATI bracket is and keeping it the same thickness allowed me to reuse their spacers & pulley. |
