So while I keep scrounging for a cost effective way to armor the wall (3/4 plywood is still $95-100 per sheet here) I will work on the RAS stand. I decided that with wall space being at a premium I could use the storage and extra mass to increase the saws stability. The start of the base is the old drawer sections from an old heavy wood desk. Sistered them together with some scrap 3/4 plywood.
