I made the rest of the firewall parts including the right F601J. The sequnece of parts is pretty straight forward but it looks to be challenging to get everything lined up to drill–especially the two gussets behind 601J. Another hour of parts prep and then I can drill everything.

Tasks Completed:

  • Made F601J-R
  • Made the right spacer and brake line doubler

Firewall Started

February 17, 2008

My how time flies. Work has been killing me. We are hitting the spring cleaning hard in the basement. On top of it all, I got sick last week. So this is my first post in a while but I am happy to report that I have started the firewall this weekend. As the picture shows, I am in the middle of prepping all the support structure.

I built a rack to hang the tail pieces from. Plus I have made major strides in clearing out an area to hold the wing racks when they get here in April. My goal is to have the bulkheads done by then, but its not looking likely.

Tasks Completed:

  • Deburred  firewall pieces
  • Made F-601 J-L
