More Wiring Cleanup
As promised: more wiring cleanup on the front of the plane. I finally got the slew of connectors related to the engine sensors tied down. Also added are the (overpriced) guides that seal the holes for the ignition wires. There’s still work to be done up here. The CHT/EGT and related wires are a mess, […]
EP 5.10 Even The Simplest Engines are Complicated
Baffle Seals
Starting the baffle seals. I’ve found using magnets to hold them in place seems to work well as they are trimmed to size and fitted. I’ll trim these and work with clecos and magnets for a while, as I’m worried about riveting without some further verification that they’ll indeed seal as intended.

Reluctant to remove the lift loop and try to source all new hardware for a crank case location, I created a rear baffle support that braces from behind the rear baffle, not in front. […]
Alternate Air
As if the snorkel wasn’t complicated enough, we need to add an alternate air door in case the engine filter gets clogged. The trap door can be open (but not closed) from the cockpit in the case of an emergency air filter/air intake obstruction. The door is filleted onto the snorkel, and will be faired […]
Cleaning Up Wiring

Cowl Blister
The horizontal intake/fuel servo installation puts the mixture arm just a little more forward than the cowl will allow, so a blister, or relief, is needed to create room with the mixture arm is full rich. I wanted to create a blister that was symmetrical and purposeful looking, machined and aggressive. I’ve seen folks use […]
