I have been using just a piece of plywood on a couple saw horses to use when painting. The air from the paint gun tends to blow around the smaller parts. Since I had some done time due to the two skins I messed up, I decided to build a table for painting. It's 60"L x 36" W x 34" H.
I used some carriage bolts and wing nuts to attach the legs, so I can remove the legs to make storing the table easier when not in use.
