Firewall deburred, center section started
Hours: 1.0 | Posted in BulkheadsFinished deburring the firewall by filing all the edges smooth. Deburring the stainless steel wasn’t as bad as I was expecting; the sharp edges knocked down fairly easily with a file, and the small file set was well-suited for the scallops around the curved edges. After the edges were smooth (and safe), I dimpled all the holes in the firewall…easy.
Located all the parts for the center section (aka F-904 bulkhead); peeled off the blue plastic and marked left/right, etc. The first task here is to drill a series of holes for various things (like wiring, rudder cables, fuel lines, and so on) to pass through. I enlarged the four pre-drilled holes, and measured/marked a couple others before it was time to quit.
