I've been contemplating a West Coast Drive for a while now. And just recently a CNC mill, CNC lathe and a plasma cutter came into our team's possession, so we're no longer limited to sheet metal. I've used the WCD SS Shifter and bearing blocks from WCproducts. Current specs are:
Dimensions - 28"x27.5"
Weight - 28.9lbs
High gear - 16fps
Low gear - 6fps
Belt driven using 24t GT2 profile pulleys
4" AM performance wheels
Bearing Blocks slide 1/2" to adjust tension, and use CAM tensioners.
My concern at the moment is that the pulley walls will bend during use and allow the belts to slide out of alignment. The reason i say this is that the pulleys are made from pulley stock and two 1/16" walls. These walls are not directly attached to the pulley stock and are held in place with a spacer an retaining ring as shown:

Any thoughts anyone?
Doughnuts would probably be a pretty good alternative to churros. However, that could be open to debate. - Calvin Hartley [more]
