Saturday and Sunday roll up. I basically did nothing but rib stitching on saturday and sunday. I was able to finish all but one rib on the upper wing split between to the two days. My fingers and now raw. To help with soreness of my hand I used an old golfing gove wrapped with masking tape on the fingers. This helped quite a bit. I was also having issues with excess wax on the rib stitching cord building up and getting everywhere. I did a search on the brain trust (www.biplaneforum.com) and found that the Kimballs use a peice of 1/8 plywood with a saw slit and drug the cord through it removing the excess wax. This worked pretty good.
