Today, I completed drilling the second carrythrough. I then dissasembled both, deburred, scotchbrite, cleaned and primed. I then assembled the structure. The outer bolts are in place, the primary landing gear hold fitting is just set in place. I'm going to add a modification recomended by Dale Murphy for the Moose aircraft. It is a .125 channel to stiffen up where the landing gear hold down fitting is. I'll need to make four of them, as soon as my order arrives from ACS.
