Heree you are Rick, I was going to be a smart ass and take a couple of photos of that stuff you mentioned and tell you it never happens to me. I have so much wrong stuff in my shop but over time it does seem to get used for something.
OK, the lines, that is an age old question and I still don't have the correct answer. If you look at your plans you can see the ink pen lines get fat and thin, usuall on the outside due to the inkers hand pressure. I have tried sanding to the inside and outside of the line and what I discovered was it made no difference as long as you sanded everything the same way. If your off your only off the lines thickness. Your choice, just do them all the same.
Dre, we have been over thnking this silly glue thing to death. One of the problems is keeping the templates attached to the wood during cutting and sanding. If it lifts when you are cutting your kit?? OOPS!!! It happens. I have used contact cement, that's when I had a real problem, it sticks really well. The covering heat gun will remove pretty much any glue and contact cement and heat posed no problem, just more work. This is supposed to be fun and not work. This Duro just works but most any spray mount glue will too.
I think I stated these are builders plans. Very few kit plans ever showed the parts in profile. You buy builders plans from model aviation {AMA} plans service, MAN { model airplane news} plans service, RCM {remote control models} plans service and a host of others. There are people that do nothing else but design and sell plans for planes. Every part needed to build the plane is shown in profile on builders plans.
I save all the kit plans after a build but that's just in case of an OOPS and I need to make repairs. I have been up on a soap box preaching to folks to make templates of every kit they buy. You can build a complete plane with them or just do repairs.
OK, enough about glue. Use what you like, it isn't a big deal. I just happen to have this Duro from something I made for my grand kids. I probably bought it at Michale's when I bought the silver glitter. I tried it on templates and it worked. It isn't going to kill your build if you leave the templates on the wood. Over time I'm sure they will dry up and fall off on there own. Then you just figure out how to get them out of the fuse or do what I would do, ignore them. I don't sweat the small stuff.
