Got the Steel Building Board done!
One of my customers gave me a 20" x 60" section of 18 gauge steel for my building board free! So today I sanded, put 2" gridlines and center lines on it and clear coated it so it wont rust over time. It came out really good and it should be very flat. I also cut out a piece of 1/2" CDX plywood and finished it with Minwax. I will put the plywood on top of my card table underneath the sheet metal to help keep it flat. I could mount the plywood to the steel, but I am afraid it would get too heavy, so with them separated I can move and store them easier. Once I put a finish on the airfield fixtures I will post up a picture of the complete system. This is almost like a build in itself setting up the magnetic build system and it should last me a lifetime, also looking good along the way!
