I just mounted my Brison 3.2 and needed 3/4" standoff for my plane. I took a piece of very old and hard 1"x8" lumber that I had laying around and cut it the shape of the back-plate then cut out the center essentially making a 'donut'. I drilled 4 holes in the corners and mounted it. It weighs next to nothing and it supports the back plate completely around it's edge. I was going to use dowels but I had the same concern as mikenlapaz with the end grain. I also wasn't happy with just mounting on the four corners with no edge support.
