Epoxy 105 209 questions



What would be a sufficient epoxy thickness and width mounting surface for hiwin type 20mm rail?

My box section is 120x80mm so the flat surface width of the 80mm side
is about 60 mm wide... would 50mm wide and 5 mm thick be enough?

After welding the overall flatness of the frame will be in the +/- 1.5 mm range... so 3.5 to 6.5 mm epoxy thickness after optimum leveling by spirit level..

I am planning to do a single epoxy pouring of the x rail mounting surface and bed supports.. this will give me a good start for a level bed vs x rail

Total needed epoxy amount will be in the 3.0 dm3 range at 5 mm thickness

40mm width and 3mm thickness of the epoxy are the minimum for 20 size Hiwin rails. 5mm thickness as all around is ok. 6x6 or 8x8 steel bar welded to frame will provide nice strong cheap channel for pouring in the epoxy. If not a continuous weld, then prime all well to check for leaks. Then pour on second step.
