Anyone have any suggestions on the best way to trim this stuff to fit? It seems thicker than the stuff I bought years ago for another aircraft. Bruce Yes, the new plastic is thicker. Not sure if that was to help with the cracking of the older style, or a material availability issue. As for trimming, I cut it with offset aviation snips to about 1/4" from "net trim", and then come back for another pass down to less than 1/16" from net, and then sand the edges smooth. There are some trim lines that show up in the smooth side of the plastic, though they seem to have some skips. These make a good first cut reference, but I would not depend on them to be exact. There are manufacturing tolerances in the plastics and in the airframes. I'd trim down to 1/4", test fit, trim again and test fit, until you get the desired installation. For sanding, I have a 3" drum that fits in my cordless drill (bought at a woodworking supply store) and an ~3"x18" long section of milled wood with 2 different grits of self-adhesive sandpaper applied to the opposite sides. The 3M self-stick paper is from an autobody supply store. I believe they are 80 and 180 grit, and originally intended for sanding "bondo" to contour. Cheap, less than $1/sheet, and I've been using the same sheets for years. I've used all sorts of tools over the years in trimming the plastic, and have settled on the offset aviation snips (available at Lowes if you don't have a buddy building an RV). You'll want both red and green handled snips, so you can cut "left" and "right" handed curves. Take your time, give your hands a rest, as they WILL cramp up from all the cutting with the snips, and do a nice job. I've worked on a few planes that looked like the interior plastic was trimmed with a chainsaw... Don't be that guy. --Bob Steward Birmingham, AL ________________________________ Message 4 _____________________________________ Time: 02:51:22 PM PST US From: Linn Walters Subject: Re: TeamGrumman-List: Interior Plastics If you have one of those Workmates, clamp a belt sander upside down and trim to fit.
