Carlo has been prototyping the overhead actuation system for the flaps with some engineering help on my part... a little CNC magic for the aluminum actuation bar grip (local straight-tail Bonanza guy is a CNC machine shop owner) and what is a multi-position ratchet quadrant to allow fine-tuning flap settings. Carlo has his panel and glare shield in place with much of his interior trim, so that somewhat complex geometry visible in the middle shot reflects the reality of fitting a longer lever and actuator grip (spring-loaded) into the cockpit layout.
I inserted the quadrant backwards for a shot before the engineering part of my brain engaged (was a long day... deliverable season) and reversed it. We will fine-tune the spring as we move forward on the design. Ends of the rod sit in Delrin bushings overhead, and the actuation tube is cut and inner sleeve/cross bolts used to allow inspection/maintenance/removal/future mod. Right now the geometry is based on movement around the usual obstructions and our 6' plus heights.
The flap lever is sitting on the under-construction elevator, so that small tubing is actually not anything to do with the flaps. The piece of aluminum anvil stock in the first shot is raw material for the cabin door hinges... already done for Carlo's doors, and will cover that CF/Spectra/Kevlar door and the shop-milled hinges in another post.
Scratch-building is the power to both innovate/optimize and to make mistakes/de-optimize... good times.

Even if you’re not scratch building, it’s a good idea.
