Firewall forward, finish, cowling components in process

Swapped the upper Adel clamp (mounted on the firewall in the center of the photo) for a slightly larger one to accommodate the firesleeved oil pressure hose.

Cover removed from vacuum pump pad to make room for the B&C backup alternator. Holding it in place today made it clear to see that the lower left nut and washers will be nigh on impossible to get started, nevermind torqued. More fun stuff…

Left side EGT probes installed. Wiring to come once the panel and its many boxes have been mounted.

Right side EGT probes installed. Wiring to come once the panel and its many boxes have been mounted.

Back to fiberglass: upper cowl micro sanded and cleaned prior to epoxying.

Firewall forward, finish, cowling underway

I was happy with the behind-the-spinner nutplate installation until I realized that I put them on the top cowl when they belong on the bottom. Argh!! What an idiot!

I fixed them today and will flox those eight rivet holes sometime in the next few days.

Cowl inlet ramps with scribe lines highlighted for trimming.

Cowl inlet ramps with initial trim completed. The glass is fairly easy to cut with a combination of left & right tin snips.

Cowl inlet drilling to the upper cowl underway.

Cowl inlet drilling to the upper cowl complete. The four clecos securing each inlet to the cowling are drilled only through the honeycomb and NOT through the fiberglass, itself. Carefully, carefully…

Left cowl inlet with prop governor clearance hole cut out.

First test fitting of the cowl halves with the inlets in place. Everything went on like it should, so I was pleased if more than a little surprised.

Cowl inlets floxed in place.

Cowlings set in place overnight to permit inlet ramp flox to dry in its actual position.
