I don't fool around, I use butcher paper and trace out every part from the kit, fuse sides and all. Then if someone wants a set of plans and templates I just go to Kinko's and have a set of both the plans and templates printed out. I sort of do what Don said with the ruler or use there window and hold one over the other, the ruler is simpler. If I have the plans and templates both copied at the same time they come out the same size so if they are off a little it doesn't mater, they are off the same. I charge for the cost of the copies and shipping because it can get costly doing it for people. Sometimes Kinko get's a bit fussy with doing a copy of something that is copyrighted so I often cut out the header in the corner, that seems to make them happy and I have no problems. It takes a little time but it is well worth it over time. As fast as kits are being discontinued it's what we have to do to keep these planes alive!!
