Detailed Bevelator Pictures

I cut some wooden blocks to just fit inbetween the vertical guides.

 I drilled a hole for the bolt - this needs to be very precise. 

When the wood is bolted very tightly in place, you put the whole lot down on a flat surface, and screw in the aluminium strip. I've shown the result here. You need to do it in place to get it any way accurate.

You can see a small gap on the right of the strip - the plastic guides on the planer sit there.

This is accurate to about 1°
