May 21, 2007 - Drilling Engine Mount |
||||||
| Today I started drilling the engine mount holes. I started with the upper right hand corner, using the pre-drilled pilot hole as a starter. I drilled first with a #40, then stepped up with #30, #19, #12, 1/4, 11/32 and finally the 3/8 reamer. I tried using the Unitbit without any luck. I had trouble getting through the stainless steel firewall; the bit kept "grabbing" the stainless. I finally got it done. This picture was before I deburred the hole; it looked better afterwards. | ||||||

Looking at the hole from the inside of the fuse. Placement looks
good.

Next I trimmed some of the bottom firewall flange with the dremel tool.
This needs to be done because the flange interferes with the landing
gear.
