Add a 1.125" hole through the middle(for the bearings), a couple of threaded holes to hold it all together and you basically have a bearing block. 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.
