Fuselage - Bulkheads

2005-01-07 - Preparing the bulkheads - firewall. (3.0 Hrs).

Finally got to start working on the fuselage. I skipped the fluting and priming, and went straight to the building part. I learned with the wing that fluted and straightened parts tend to warp after sitting around the shop for several months, so I will flute and prime them when I need them. I always eat my vegetables with my meat.

One thing that I would suggest is to deburr the stainless steel firewall before you do too much work on it (I didn't). This thing is really sharp, and could easily slice a chunk out of your fingers and hands (I didn't, but I could have).

First step is to fabricate the F-601J angles from AA6-187x2x2 1/2 angle stock. This is the 12" piece of angle. I know a lot of guys like to use their band saws to cut this stuff, but I am not so sure about cutting this thick piece of aluminum with my bandsaw, so it's time for the ole hacksaw.

The first piece has been cut off, and I am cutting one of the corners. Two corners need to be cut. The cuts are not the same, so pay attention.

Here is the right side part all cut and filed, needs deburring.

Cut the second part, then place it back-to-back to the first part, and mark it. This way each part will be a mirror of the other--you can't go wrong.

Both parts cut, deburred, and polished.
