Hello... I've got some repair questions due to a lack of building experience.

My twist had a hard "landing" the other day, which resulted in some cracks in the fuselage ply. I used card stock to design a splint to reinforce the crack. I will use this template to cut out the actual piece from 3/32 ply. Now knowing next to nothing about working with wood, and even less about trying to do anything with any precision, I bought a "coping saw" with what I thought was a pretty fine blade. However, I'm finding next to impossible to cut the ply with any precision, and with out shredding the edges of the ply. Due to lack of options I tried to carve it out with an Xacto blade, but I'm sure there's a better way?

So, what would be the best tool to use for cutting out precision parts from ply? I'm thinking of maybe getting a Dremel with the router accessory, would this be a good choice?

What would also be good way to cut triangle stock? I've been using the xacto blade for this too, but it also crushes the wood a little.

With the convienence of ARFs I guess building and reparing is a skill that is not as necessary, but once I have time and space I want to build a few planes to build those skills, if for nothing else than to be able to recover from my "oppsie" landings.
