larry, this is roger mitchell, I work at TWA-AA overhaul in KC Mo, when we do composit repairs we use a perferated plastic on the cloth/resin layup then a solid plastic film, tape down firmly both layers, second larger than the first, and use a plastic applicator to push out any air bubbles, on the airliners we use vacumn( 21" hg) for air removal and pressure & heat for curing, probably wouldn't work on a KR. THE NEW " SARAN WRAP " with the cutter works wonderfully. layup is commonly done with the first piece the size/shape of the hole then up to four layers( depending on original thickness) each 1/2 larger than the first on all sides layed on in reverse order. the easy way to accomplish this is to first work epoxy into the cloth between two pieces of heavy plastic film,draw the shapes needed,cut out, and peel-n-stick. if you want you may call me at 816-305-9689 ----- Original Message ----- From: larry severson To: KRnet Sent: Wednesday, April 28, 2004 6:48 PM Subject: KR> hole in LE
I am going to have to patch a hole on the leading edge. matching the contour is easy, but do I have to remove all of the paint, primer, and filling down to the glass to get a good patch adhesion on the 1-2 in around the hole.
