Welcome Tom and Thanks for the kind comments.

I have not added to this thread in a few years... but would like to add a tool that seems to fit in with what is outlined here.
That is the Aerobroach system of doing the right sized slots for the hinges. Since getting mine I have punched the correct sized slots in practice for my next project. The TF P-51D Giant Size of which I just need to hinge, cover, paint and etc.

Seems like these work well when I tried them in some scrape balsa...
See here if you are interested www.aerobroach.com and view the short how to there.

Let us know how it goes.

Watch Your Six !
