I finished making the center and web spacers today. Then I fit them on the spars and drilled them. I then started on fitting and updrilling the ribs for final rivetting. I spent some time studying the plans and thinking about the process for assembly of the wings. I decided to build them both at the same time .. that way as I figure out a step and do it to one I can just do it to the other. I thought if I completed one wing then should I want to refer back to the first one it would be all closed up. I got a couple two by fours and made brackets to hold them in the vertical position. I can then just roll them back to horizontal if I need to. I'll see how this works out.
