A little UPH Tech. - TRIM PANELS
JakesBackyard:
Now use a black sharpie to mark the centers of all the clip holes and around each handle stem. Trace the outside edge of the door remembering that what you will cover the panel with takes up to another 1/8" around the outer edge. Be as exact as possible. This is where attention to detail pays in the end. Here is the finished vinyl on the door. Now out on a white paper on the table. It's good to write "R" or "L" on the vinyl so you don't happen to flip it over the wrong way. Note that all the markings show up on the white backround.
JakesBackyard:
Now get out a piece of panel board. It is available from most upholsterers or at MAC's. Make sure you get the waterproof (black on both sides) thicker one. It is available in 32" x 48" which is big enough for most panels. There is also a larger size available. Make sure it is the thicker (about 1/8"), as the thinner ones are not waterproof and will warp up fast.
Spray a light mist of the adhesive on the back side of the clear vinyl pattern and smooth out onto the panel board. Mark the clip holes with a light hit of the hammer on a scratch awl. It's just a mark to know where the center of the clip hole is. Now use a hole punch (various sizes used) to mark and eventually punch holes for the handle stems. Handle stem holes should be made larger than the stem enabling the panel to be shifted a little if necessary. Use a utility knife to trace around the outer edge, following the sharpie line carefully. Just a light cut to basically mark the outer edge for now.
Peal off the clear vinyl. If you are doing a panel with a roll down window, save the vinyl, trim off excess beyond the clips, and glue it on the door as a vapor barrier.
JakesBackyard:
Now trim the edge of the panel on the mark made with the utility knife. It takes two to three cuts with the knife to get through it or grab a jig saw and use a fine toothed blade to cut around that first mark made. 80 grit sand paper can be used to smooth out any rough spots.
Punch holes for the clips with a 3/8 to ½ inch hole punch. If you are using a metal trim clip, the holes need to be ½ inch away from the scratch awl mark because the clips are offset. If using the plastic xmas tree clips the holes are punched on the center mark and made oblong with a second punchout to enable twisting the clip into the panel.
JakesBackyard:
It's about done. Put in all the clips and test fit the panel. If I'm using the plastic clips, I only use a few to initially check the fit. They are tougher to get out and break easy. Just check to make sure all the holes line up. Now is the time to check the fit of all handle stems, (I'm marking one a little larger with a pencil) and make sure the outer edge is where it should be.
JakesBackyard:
Here it is all mounted and ready to cover. I make and mount all the side panels and then draw out my patterns for uph. with chalk.
One more post to come.
