Title: Prop governor cable bracket; Mixture bellcrank
1. After some recent bafflement about how I would come up with a prop governor cable bracket, I recently ordered a part to use as a backup to my primary plan. The backup part arrived today, and I decided to try it instead of the custom bracket I've been making. After some fiddling with it, I noted that it didn't lay flat against the governor housing because of a lip on the housing. I determined that two washers per attach point would probably work, but they would need to have a flat side for clearance. So the first order of business was to grind down six washers. I then stuck two washers onto the bracket at each mounting hole, using Fuel Lube. 2. I mounted the cable bracket using the stock M4 screws, but substituting #8 star washers. While the mounting screws were loose, I took the opportunity to rotate the governor housing so that the control arm was in the proper "clocking" for the cable. Then, figuring this bracket will definitely work well, I tightened all six screws. (Safety-wiring these screws will take place after I'm 100% sure that the governor clocking is correct.) 3. I tentatively mounted the cable tab at the end of the bracket arm. Again, I will tighten its hardware when I'm sure that the control cable will be positioned correctly. 4. Did a few more minutes of filing on the mixture control bellcrank and the auxiliary oil plug on the engine case. The bellcrank now fits great. I just need to have it fully stripped and powder-coated. 5. Took the bellcrank to a friend's hangar and bead-blasted it. Unfortunately, the fine media in the blaster wouldn't touch some of the existing powder-coating, so I'll have to address that tomorrow.
