    This is how I'm going to have my fence for pouring the epoxy, I might put an extra cross channel near the front of the frame as an extra channel for self levelling.

    Depending on how good it flows I was thinking about either a central aqueduct (epoxyduct ?) or two, one at each end. Obviously two are more wastefull than one. You don't fancy using the draught excluded idea then for the fences then ?

    I'm going to test on a miniature set of welded steel first using some steel offcuts. I'll weld up a practice piece first like this...

    Just hope it doesn't use too much epoxy...

    Might try the draught excluder on the test piece....can see it being messy to get off after the epoxy sets?

    Had a little play at lunch with the pillar drill and a bit of 60x60x5 RSA as I was thinking of making the dummy gantry base out of steel (plenty in the scrap bins at work cou"stock"gh) to cut up and mess with. I printed the hole pattern out on some paper and taped this to the bottom of the angle and centre punched the hole positions (high tech stuff this) prior to drilling them. Used a 6mm drill bit for a bit of clearance as the holes on the carriages are Tapped M5. Bolted the carriages to the angle and I reckon it should work OK and will save me spoiling a good bit of 10mm 6082 Ali plate.

    I will get some draught excluder and try Eddie's moat method on the underside of the angle so as to get a level surface to mount the carriages on. I know for the sake of getting the rails parallel I don't need to do this but it means I can try the epoxy out to see how good it is and also try Eddie's foam moat idea at the same time

    I did a test pour today and it's looking good. The draught excluder worked fine but where two pieces butt up at corners it needs a bit of glue between as there was a slight leakage through the joint. I'll do a full report in my own thread after it has cured. Also I'm thinking that when the moat is removed the edges of the epoxy would look a lot better if a bead of liquid nails was run down, like you would with sealant, then run your finger along it to create a nice fillet that will set hard and can be painted over.
    It looks like the epoxy did not penetrate into the foam, which was my biggest worry, and I think that's because the foam is waterproof.

    Splashed out on some transfer punches to transfer the hole patterns to the other piece of 60x60x5 angle. Will weld up the cross member next week...really want to spend more than 45 minutes on it at one time.

    I'm selling off all my RC Helicopters so there's more room in the shed so I should be able to get out in it and do some work on the gantry soon I hope. Just have to man up and try cutting the ali plate and stop worrying about messing it up
