So just poured the epoxy (West System 105-209) no leaks - so far. MDF frame nail gunned and coated with two coats of sealer so hope it will come away neatly. Then mastic and clamped in place. 40mm wide and 30mm wide bridge, should give thickness of 5mm from 1Kg of 105. My wood drying kiln is on at the moment in the workshop providing some of the heat. It runs at 30 degrees and leaks out into the workshop. The rest of the heat provided by electric radiator and fan heaters. Started pouring at 16 degrees and its going up.

Looks nice and sturdy! Well done and keep going, but don't scrimp on anything. It is worth it in the end!

So while waiting for the resin bed to set I have been making up the gantry, z, y and x carriages etc.
Not having very good marking out equipment, (surface plate, vernier height gauge etc) I decided on using a wooden indexing type table on my pillar drill. This is because I can plane wood to accurate thickness. Then you mark the first point and drill, then index around this point using accurately planed pieces of wood, adding or subtracting them. Making sure you get all the swarf out of the way. Sorry if this has already been done by someone on the forum but I’ve not seen it. Thought it might be usefull

So just finished fixing the x rails onto the resin bed, 3 weeks after pouring. Many ways to fix the rails I read on the forum. I went for a straight edge (Probably not) ally 50mm box section. Clamped to side of bed then spaced 30mm to side of rail using lengths of 30mm diameter bar. This positions rail in centre of 80mm box section (30mm + 20mm rail +30mm =80mm) Clamped rail, drilled and taped each hole then moved along a hole at a time. Second rail repeat process and checked and adjusted gantry, to make sure smooth running and no nasty noises. Checked with DTI.
We will see what its like when I cut something in the future.
