1. Reset the fuselage on some jack stands and leveled. The rotisserie wont stay steady enough for the gear drilling.
2. Marked a line 3/16" inside the outer edge of the langeron for proper placement of outboard gear wearplates and attach brackets. Positioned the gear in brackets and snugged up the single inbd center bolt. Dropped bolts in the other 4 holes for the attach brackets and wear plates.
3. Attached 2 plumb bobs on each leading edge gear leg. One on obd end and the other inbd. I layed a string on the ground from the obd points. A plum bob was also strung off the rear most bulk head (tail) using the tool holes for center and marked point on the ground. I fiddled with the gear mounts and legs until they lined up on the string and then I measured distance from obd points to the rear point on each side. I finaly got it to 166 1/18" on both sides give or take an 1/8th inch, well with in the 1/4" allowable limit. I then marked the edge of the gear on the bottom floor skin to help show if gear is staying in alignment while drilling.
4. Using my hand drill and 3/8" drill bit, I drilled the 2 holes through the floor skin, longeron and weldment of outboard brackets using those holes as guide. Did the same for the left side. I then used 5/16" bit to match drill the inbd brackets and wearplates to the floor panel and inbd gear bold weldments. This realy heats up the drill. I took it slow with plenty of oil and cool down periods to try and keep motor from getting too hot. This worked great.
I still have two holes on each obd wear plate that is below the belly skin. I will do this tommorow morning possibly. Its breaking 100 in hangar now. Time to go!!
