Wow, those epoxy sides came out very nicely. Also a great idea to use those 8mm square bars on the sides of the epoxy.

That base looks VERY solid and straight. I'm wondering how flat those X sides were before the epoxy, did you perhaps check that? The reason I'm asking is that I'm hoping to get away without having to use epoxy because I'm not getting something similar to the West Systems stuff here so I need a plan B.
