Quite an Unusual one

Syliavski I dare to say that your last solution is not sure that will work as you imagine. I have never work on research but I think that a basic principle must be to make small steps every time. With your last solution you move the bridges from the middle to the edges. Who told you that the epoxy will be spreads the same way without the two middle bridges. I think 3000mm is too long distance for 5-7mm epoxy thickness. If I were you I will shim or for fill the gap with epoxy and then sand down as Dean suggest. If I had to recast I will use the same arrangement as your last casting try with the difference that I will make the bridges wider near the side tubes( where the rails will rest on). In other words I will put the reservoirs next to the spots that you mention the problem. As the epoxy has the tension to shrink at a specific spot, make your correction at that spot. See below to see what I mean.
