Anyone interested in 83 Pace Arrow Tear down and Rebuild?

I noticed on the hole saw, there were 4 slots around the outside of the saw.

Sooooo, I figured, since they are equal distance apart, after drilling the hole, I cut off the end of the 2 x 4 until I had 1/4 of the outside diameter in the wood.

I figured that would give me a right angle transition and should work just fine.
