1. Just take it to a local copier and they can do what you need to scale it up to the right size.
2. You can trace it out, scan it to your computer or even print it directly off the plan if need be. When copying plans, I always get two copies made. One for building then one for cutting out templates. The extra cost involved is minimal. From there I cut out what i need a little outside the lines(about 1/4") then glue to a sheet of that there poster board that you can get at the dollar store( 2 or 3 for $1). Then cut out on the lines and you have a template. When tracing to balsa I always give a bit of extra so that i may sand down to the right shape(1/8" extra is enough.
3. Fuse is cut out with a modelling knife if it is a 1/2a size profile, and anything larger gets the scroll saw or band saw, whichever is being used at the time.
Ribs can be cut one at a time, but two rib templates, one at either end, bolted through a stack of blanks works pretty quick. Get the rib outline done first then for spars pick a piece of balsa one size smaller than on the plans and glue a piece of sandpaper to it then ust it to make your spar slot.
4. You can buy leading and trailing edges, but around here they don't carry them so I just make my own, or easier yet, modify my leading or trailing edges to something that works for me. Easy to do and keep the same profile and/or design.

Hope this helps a little for ya.

p.s. only one other little building tip. Remember to install the flap/elevator control rod and leadouts BEFORE sheeting center section!


I see you beat me to it there Build Light. Shows how slow I type!
