Longeron/upright cutting aid

Recommended Posts

I'm building an Airsail Voltimer which is  a stick and tissue vintage type cabin monoplane.

It is fairly simple to build but as usual I am trying to build it as best as I can (better than the my last build).

It has a basic fuselage with 5 mm square longerons, uprights and diagonal braces.

Cutting the uprights to exact length and getting any angle correct has always been an 'eyeball' job but I saw a method recently (can't remember where!) that takes the guesswork out.

It's very simple, take a scrap piece of ply and cut a slot in it twice the depth of the stripwood but the same width (in my case 10 mm deep x 5 mm wide).

Place the stripwood over the plan on both upper and lower longerons then place your new marking jig over the upright and against the inner face of each longeron, mark with a pen or pencil.

Cut the upright just over size with a razor saw (I discovered that sawing one direction only stops the wood ripping) then sand the ends until the pen marks just disappear. I use a disc sander for this.

Hope the photos are clear.
