Making the ribs for the wings

Ribs have to be cut out of the 1.5 mm plywood using templates from the plans.

Templates are created from the plans

Holes are cut out in the plywood for the ribs to keep the overall weight of the plane as low as possible.

Ribs are glued together using a jig made from the plans.

There are about 80 ribs to make. 5 different types.

Then the ribs need to be fixed on the spar

And suddenly it even looks like a wing. Two more wings to do !
