Brief Description:	Lower firewall + upper firewall
- At the lower firewall, finished drilling the pilot holes into the aluminum frame. - The holes along the bottom of the stainless steel firewall is another matter altogether. I haven't got any cobalt bits yet. My current 3/32" bits just will not go through, even with cutting fluid. In photo #2 that "dent" was a 3/32" bit after 5 minutes of work with cutting fluid and SLOW drill speed. - So I went on to cutting out the upper firewall pieces F17-03 and -05. I still have to make the center cutout in the larger pieces.
