Steve Robinson's Clip Wing Project - Part 9

Clipwing parts. Here's a photo of the master that I used to cast the new fulcrum. The original fulcrum was cast and was of a fairly low grade aluminum. My part was cast in A383 and is a stronger alloy than 6061. Casting is more than adequate for the stress that this part will be subjected to. With the bronze bushings installed there will be no noticeable wear for the load that this part will incur during normal use.

Crazy late fall weather here, afternoon temps in the mid 60's.  We need rain though.  Two great flights in the 110.

More Clipwing photos. The control stick fulcrum was badly damaged at some point. It was twisted and poorly repaired. I decided to cast a new fulcrum. I drew up a new drawing in CAD using the original print for reference and dimensions. Once in CAD, I enlarged all the dimensions by 6 percent to account for shrinkage in the foundry process. With the new dimensions I fabricated a master of the fulcrum in a proto-typing tooling material called Ren Board. Then off to the local High School that has an aluminum foundry in their metal shop. After a couple of tries, I had a good part that was then drilled for bronze bushings and finished on the outside to proper dimensions. Then bead blasted to a smooth finish.

More Clipwing photos. The control sticks and assemblies were disassembled and bead blaster. The control sticks had been cut short and a 3/4 inch tube installed for a smaller diameter grip. I spliced in new 1 inch tubes for new vintage grips and machined plugs for small push-to-talk switches. The trim handle assembly was badly rust-pitted, a new lock nut was welded in and the assembly was primed and sanded a couple of times to finish out the pitting. New springs for the trim handle were sourced from McMaster Carr. The handle was sanded smooth, then nickel plated and all the small hardware cad plated.

 Cold and clear morning.  Pretty good wind to start but an hour later it was mostly calm.
