Got two of cutouts glued together today. Used drywall screws that I will remove later, to hold it together. Put my old manifolds on their for some extra weight. Final measurements came out to 1.08" of thickness, was only + - .02" around the keyhole. Pretty happy with that.
My fiberglass supplies came in also today. this is just a small amount of what I got. I have 3 gallons of resin and lots more strands and silica.
Saturday I plan to glue the wood in with Pb. Only using two sheet of 1/2". Will see where that gets me. My ultimate goal is to be at 2.00" when done.
