Thanks Money!
The mount was cut with a jigsaw and some fresh Heavy Duty bits.
The bearing hole isn't perfect but came out pretty damn good... I used an 8ight-T diff and it used 14mm outer diameter bearings. I used an 1/2 inch drill bit (only 12.7mm) and made the hole in the right spot. Then with the drill bit chucked in the drill press I slightly rotated my hand while holding the mount. This enlarged the hole very slightly. The bearing was a bit too tight, So about 1 minute with some sand paper and I had the fit just right...
If you plan to use a more standard size CD bearing (16mm) I suggest getting a 5/8 inch drill bit (15.875mm) and just do a little more sanding. You can get them in there perfect with a little time and patience. It wont take long to sand away .125mm
Then I just used a Belt sander and File to get the edges all pretty and sanded with wet 150 grit. (400 would be better)
PS for the motor mount holes I just removed a motor end bell and clamped it on the mount to get the 25mm spacing just right...
PSS: Get some Good Quality Drill Bits. I broke or Dulled 4 or 5 bits drilling this mount and braces. As you can see in the top middle of the mount.
