Take your time ! This is NOT a one man operation !
I was lucky as my "project" already had the fus. fittings installed. My center wing was "matched hole tooling" and when I drilled a pilot hole in the center puched spar web it lined up PERFECTLY with the fus. and spar fittings ! I maybe had to ream out a thousands to get the bolt in ? I used a set of modified saw horses to initally set the wing in position. Then I used two floor jacks with 2 x 4 supports under the wing to carefully "jack" the center wing into position. Jacking up one side a little then the other side to get the bolt holes in position. Remember it is just me and the wife and she is crying seeing 27 years of work ! I believe there is a NL that walks you thru the process....not my process. I was also lucky as the rear spar fittings lined up almost perfect also. RB
