These are the pulleys and QD bushings that I used
McMaster- Carr
6495k514 Pulley
6495k522 Pulley
6086k516 QD bushing
6086k214 QD bushing
Bearings
6494k33 Nickel Plated cast iron, Flange bearing
Shaft
8377T28 SS 1" drive shaft, 1/4" key way
Grainger
Drive Belt
1DHT2 1" wide H gearbelt
I used T-slotted extruded aluminum rail 15 series, to build the frame.
The motor plate is 1/4" aluminum. There are 2 leveling bolts that push up on the motor plate to tension the belt. You can see photos at Electric Seas

I've decided to use timing pulley's/belts or sprockets and chain along with captured roller/thrust bearings but am having a tough time sourcing them. I wouldn't be opposed to a gear reduction either provided a "bullet proof" reputation. The motor of choice is the ME0907 for it's lack of brushes, performance, and affordability. By my calc's a 2:1 to 2.5:1 reduction will be needed to maximize performance. Any ideas would be appreciated.
