Re: Cabin heat with an Aerovee - another approach

I've made some more progress on my heat installation. A big problem was where to mount the heater control knob. I had very little panel real estate. It looked like I could mount it to the left of the trim wheel, so I 3D printed a mockup and taped it in place. One attempt to use the trim and that was shown to be unworkable. I have a real vernier type mixture control, which uses a huge nut to fasten it to the panel. The body of the mixture is an approximately 1/2" OD steel housing. So I thought I would try to use an adel clamp and mount it to the mixture under the panel. Here is the bracket:
Before I made it all nice, I tried it in place. Seemed pretty good.
The black heater knob was actually a choke cable from Amazon: https://www.amazon.com/dp/B07NQ6RNPJ
It was hard to see under the panel, so I painted it white and turned the choke icon into an 'H' for heat.
Here is a closeup of my flapper, clevis and swivel. The flapper and clevis are stainless. I bought some titanium off of ebay for the flapper, but it snapped when I tried to bend it in my sheetmetal brake. Back to stainless! Also the hinge is a stainless hinge I bought off of ebay. I took it apart and got two sections with no screw holes, so I could put in my own rivet holes.
Here are both ends of my cable mount cleaned up. They are 7075-T6 angles that I had in the junk box. The cable sheath grabber is stainless. First I made the rounded hat section around a drill bit,using the vise. Then I cut off a little piece of an AN3 bolt that was a little shorter than the hat section so I could form the ends around it. It seems to hold the spiral sheath really well when socked down.
I can't remember how many pictures per post is allowed so I'm going to do another post for part 2.
