L04-01 Tri-Gear Main Landing Gear Mount.
Today I decided that I had the left mount in the proper position so I started drilling holes.
I first drilled the 3 holes that go through the lower skin and the longeron to the #40 size.
I then drilled the 8 holes that go through the lower skin and spar tunnel to the #40 size.
Next I used the 90 degree drill to drill all but one of the holes that go through the angle on the side panel to the size #40. The lowest hole I could get the angle drill in position. I will remove the angle and the mount and drill this hole outside the fuselage. I will also updrill these holes to the #30 size outside the fuselage.
Then I drilled the holes that go into the aft side of the spar tunnel.
I then went back and up drilled all the holes to their final sizes except for the side panel angle holes.
When I started up drilling the holes going into the spar tunnel the drill did not want to go through the steel mount. After trying a few different things I realized the speed of the air drill was probablly heating the steel so the drill bit would not cut. So I got out the cordless drill which goes a lot slower and it work just fine. Lesson learned fast is not always better.
