After the debacle I had priming the rudder parts I decided to build some table tops out of wood and mesh. The reason I had such bad results was due to using a flat piece of plywood as a surface. The light parts were blown around because the spray hit the flat surface and spread out. A mesh surface will keep that from happening again.
The plan was to build three table tops about the same size as the plywood sections (48 in. X 32 in.) I picked up six 1 in. X 2 in. X 96 in. pine and three rolls of 1/2 in. X 3 ft X 5 ft. wire mesh at Home Depot. You need six 48 in. sections and nine 32 in. sections of the 1 in. X 2 in. boards. Glue and screw together then roll the wire onto the table and staple.
I managed to get two of them built and decided to defer the third because, frankly, these things are a PITA to build. The wire is difficult to unroll and straighten. If I really need a third I'll build it at some later date. I'll see how things go with just two for now.
Building the frame for the table top.
Two done. Third on hold until I determine I really need it.
