Master Alex,
My building table is 7'x3' and the glass that I ordered is 1/2" thick and tempered. I will be using the magnet systen that is on the airfield models web site. I ordered the magnets and the wood needed to make the fixtures and just waiting for everything to arrive. I'm not worried about breaking the glass table, I'll use my ARF table for anything other than laying down sticks

. Here is a photo of the table (the one in the back) before the glass and the two shelves. I'm still in the process of putting my shop together but not having it completed hasn't stopped me from having planes, it's a work in progess.
