While that frame is drying, I turn back to the top shaft mounting block. It needs a 1 inch hole for the shaft.
And it needs a hole for the tracking adjustment bolt. A T-nut too.
This is with a sample bolt installed. Turning the bolt will tilt the mount and the shaft in the mount and will adjust the tracking of the blade on the wheels.
The mount goes in the frame I just glued up. And the frame is held to the big saw body frame with a couple of L brackets. So I made those L brackets.
