The main landing gear legs seem fairly simple to construct. One thing I did notice is that the RS-540 plywood is just large enough to make the required for panels.
I cut the RS-540, RS-14, RS-12 and RS-9 pieces and glued the legs together but only putting the ply on one side.
I then varnished the inside area of the assembled leg and the inside non-glue areas of the other plywood skin.
Once the varnish is dry I will glue the plywood completing the assembly.
