Fuselage Formers

The last couple of days have been spent tracing out and cutting the fuselage formers. The plans called for a mix of 1/8″ ply and 1/8″ balsa to be used. However the widest sheet of balsa i can get anywhere is 4″. This is not wide enough for the formers, I’ve.taken the decision to change this to lite-ply. Although this will make the fuselage slightly heavier it should be pretty negligible. At the current pace I should have all of the formers completed in the next couple of days.

I’ve been thinking about building the fuselage on some form of jig to ensure straightness. My current thoughts are to use some 4″ blocks of wood with spacing controlled by a dowel or metal screw rod. This would maintain squareness of formers, and then just pin the centre crutch to the blocks to keep horizontal squareness. Anyway I’ll continue to play with this idea and post up a picture if it works out.

Start of a new build

Made a conscious effort to start on a new build that i have been pondering for a while. I’ve had a copy of the plans for a few months and just finished a trial build of a Lockheed Vega. This build is of a 78″ wingspan B-17G WW2 bomber, named the Bit o’ Lace. The plans were created by Walter Oetzell, but there’s not much information of other builds from these plans on the internet.

The plans are missing some key information which the builder needs to take into account. Firstly 3 wing spars that hold the wings to the fuselage have no template on the plans so must be created by the builder. Secondly there is no mention of the required dihedral for the wings, although from a few internet searches this seems to be between 4-6 degrees.

The first task on the list is to start marking out the formers and wing ribs onto Ply and balsa sheets ready to be cut. As i don’t own a cnc machine these will all be cut by hand using an electric scroll saw. I’m using a different method of putting the templates on to the wood this time. Previously i’ve photocopied off the plan and glued the templates to the wood with lo-tack spray glue. I’ve come a cross a couple of issues with this, namely the template not sticking properly, as well as glue overspray. This time im going a little more old school using a set of compasses and tracing paper. We’ll see how successful this is as we go!
