I¡¯m a little late to this thread but I thought I would chime in. I purchased mark¡¯s kit. The jigs are nicely done to build the ribs in. If you purchase the kit make sure to wax the daylight out of the jigs with a good carnauba wax. The wax will help make your jigs last longer. When I was finished building the ribs all of the parts fit together as I expected. Your spars are all cut to size. His kit is slightly different from Steve¡¯s plans. On the last outboard full size rib he does not skin the rib on both sides with a full covering of plywood.?
on the inboard taper of the wing near the fuselage I thought my leading edge profile is much blunter than the rest of the wing. ?I may change that just for cosmetics.?
I purchased my plywood from a boat restoration shop in Minnesota. The price was good and I was close enough to just pick it up.
The kit is not cheap. If you are the person who enjoys putting a puzzle together you can choose to trade dollars for convenience. For additional effort you can purchase cap strip and plywood and cut out your own gussets, mill spars, build your jigs and build the wing.?
note: ?I was strongly encouraged to plywood skin the outboard rib on both sides.?
