Drill Firewall to Skins, make attach straps and start auxiliary longerons

This week I only managed a total of 4.5 hours in the workshop.

I started by putting cleco (clamps) in every other hole of the firewall to fuselage. I did that because I wanted to pull everything together and have the most accurate match drilling.

With the fuselage being stainless steel I made sure I used a different drill bit as SS can really blunt tools quick.

Once all the holes were match drilled I then made the 4 attach straps that hold the golden F-704 bulkheads to the upper (bottom in the picture) longerons.

I also started work prepping the auxiliary longerons. These are basically aluminium angle used on the front of the fuselage section.

No pictures for those bits though cos I forgot!
