We add a .125" chamfer to fit in the filleted slot, and make it .010" under the width of the frame tubing to make sure it clamps. Check out our cad and you'll see what i'm talking about. Our bearing blocks can be machined on a standard mill no problem.
This is also how 60, 254,968, 1538, and many other WCD's are setup.

254, etc.... use a much different design that is similar in functionality, but different in execution.

Our blocks are pretty much a block with the bearing hole for both bearings. This makes each face plate effectively a large, special shaped washer.
