I think rather than try and shim the unsupported bits with shim material I'm just going to squirt some structural 2 component polyester resin in there, it is close enough and I will just make it worse trying to shim normally.
In the picture you still have the protective coating on the plate so you can't trust those measurements if you did it with that still on.?

Regards the Epoxy and bridge etc then I've probably done more pours than anyone here, I've lost count of how many but it ranges from Medium and V-large, my experience is between both you and Clive. I agree the moats are better outside the frame but you need them both ends of the machine. Also, make the moats lower than rail surface as this seems to help the flow. However the most important I find is the temperature, keep the temp on the low side of what's recommended as it slows the curing process and gives it more time to level. The only tricky bit is it's a fine line between just right and too cold and it not setting correctly.
