    Brilliant update Eddy, great idea with the draught excluder.

    I've watched a few videos about clear coating wood with epoxy. To get the air bubbles out they normally play a blow torch flame over the surface for a fraction of a second. I guess the faster you can apply the heat the less you move the epoxy around. They always remove the majority of the bubbles before pouring though and I've seen two good techniques for this. The first requires some skill, you pour the epoxy from one container to another but lift the top container up as high as you can creating a very thin but constant stream. It seems the thin stream forces the bubbles out on it's way down. I've tried this and it works but it's easy to screw up and end up with epoxy everywhere. The other is to pour the epoxy into a big tub and put it under slight vacuum which will suck all the bubbles to the top, obviously you need some way to make a vacuum though and you've got to be careful not to fill your vacuum making device with epoxy by accident :-). Next time I need to de-bubble some epoxy / resin I'm going to give the vacuum method a go as I have a spare vacuum cleaner hanging around.

    What are you planning on doing about the meniscus? I was wondering if it might be worth trying to route a chamfer into the epoxy as that would remove the meniscus, clean the edge and help stop it chipping all at the same time.
