One of my favorite things about the H.A.M.B are the tech posts so, I thought Id take a stab at one. The following is the breakdown for fabbing your own door panels from scratch. Since not everyone has a sewing machine sittin in the corner of the shop and because we all dig 2 inch pleats Ill show this example using press pleat vinyl. All of the supplies described are available from your local trim shop, hardware store or online. First up, you need to prep your door for the pattern. Make sure all old clips or screws are removed as well as your inside handles and garnish (window trim) mouldings. From here, its a good idea to run a 1/4 drill bit through the existing clip holes. (Use a drill stop .trust me!!!!) This is to make sure your clips will snap into place with little effort. If your door doesnt have holes yet mark them in about 5/8 and roughly 5 apart all the way around the door. Next up, cut a piece of butcher paper or contractors paper (available at the hardware store in rolls) larger than your door. Spray it on one side with a liberal amount of 3m Super77 spray can glue (another hardware store item). Once you have it good and sticky, take it to your door and stick it with plenty of paper hanging past the edges. Now trace the edges with a pencil and poke all of the door panel clip holes. Also mark any door handles or window cranks.
