I ordered some one and two wire spark plug wire adel clamps from Sacramento Sky Ranch. The order came in today, so I installed some of them on the cylinders. These are stainless steel with silicone cushions that are good to 400ºF.
The forward cylinders get one wire clamps.
The aft cylinders get two wire clamps. These are sweet because they’re formed to clamp two wires instead of something cylindrical like typical adel clamps. I picked up a few more of the two wire clamps to anchor the spark plug wires the rest of the way to the magneto.
I also cut down the rear spar a little bit where the forward elevator pushrod passes through. The cutter got away from me a little bit and widened the hole as well on the right side. I put a little self-etching primer on the cut edges.
I then temporarily installed bolts in each end to check the fit. There is almost 1/4″ of clearance where the pushrod passes through the rear spar cutout. Even under high g loads, the pushrod shouldn’t be able to flex enough to contact the spar. This is the rear end where the forward pushrod attaches to the elevator bellcrank.
This is where the forward end attaches to the center control column.
