I had an extra hour or so today to sneak into the construction zone; so managed to rivet the 906 spar doubler to the HS 903 rear spar. I am now ready to make the final assembly of the HS. I will first have to get some Pro-Seal as recommended by some fellow RV'ers. So, for a guy that said he would not work on weekends, I managed to get in about 3 hours of work over the two days. Please do not tell Susan.
