I have just purchased a small 300x300 surface plate to use when calibrating my machines when its finished. Very similar build to yours, steel frame with supported round rails.

I've seen you're looking into epoxy levlling. I didn't know about the right way to do epoxy leveling when I built my machine but would strongly recommend you look at other posts on the forum that describe using West Systems 105 resin with their very slow hardener type 209. This looks like the best way to get your rails as straight as possible from day one and my biggest problem, the twist in the Y axis rails, would not exist if I had done a better job of researching this forum before I began the build.

I look forward to seeing your finished machine.
