Prop Install

Today was a major milestone day, we installed the prop! This was something I’d be holding off on, but with my parents here to help, it was a good opportunity to get it installed.

The first step is to remove the a cap which then allows oil to pass into the constant speed prop hub. There are different methods, but having never done this before I thought it was best not to drill anything, and instead try to remove it with a rod and hammer. Since I couldn’t bring myself to hammer away on the end of a very expensive engine, I let Dad do the job. His steady hand made this an easy task, although we were surprised at how much force it took to eventually pop it out.

The prop needs a couple of spinner plates mounted before it’s attached to the engine, so we followed the manual and Vans instructions to install these.

I also cleaned out the area behind the cap we removed to ensure the prop would mount cleanly.

Borrowing my neighbor’s engine hoist, and with a strap suspending the prop, we carefully hoisted, positioned and installed the prop. It only goes one way, and cannot be rotated at this time, so we had to carefully measure the clearance between the tip of the prop and the garage door, and other shelving. It fit with about 1 inch of clearance. I think I’ll find a way to put the plane into the garage nose first, which will solve the clearance issues, and maybe allow me to keep the canopy installed.

Everything went well today, and I’m stoked to have the prop on now. None of the prop bolts are final torqued, I’ll wait until I’m confident it won’t need to come off again before doing that.

Spinner mount

Tonight I riveted the two pieces of the spinner mounting plate together. I was able to squeeze all of the rivets.

I then started back on the canopy. I have a few canopy jobs to complete; wiring, leather glare shield install, canopy fairing final sanding and painting, and then the guide pins.

I started with the canopy lock micro switch. When closed and locked, the micro switch is depressed, closing the circuit and sending a signal to the panel. In the event the canopy is not locked, a warning appears on the panel.

The wiring should have been easy, just check the switch, install two spade terminals, and it’s done. Unfortunately I the process I found that one of the wires is caught somewhere in the channel inside the canopy rail. Luckily the wire is still making a good connection, but I couldn’t feed the excess wire into the channel. I ended up shortening up the wire and messing around, but it worked out in the end. Anyway, the black wire is the one that is jammed somewhere.

Propeller and spinner

Today I unboxed the propeller, which has been sitting in its original shipping box for about a year. I wanted to verify I had everything, and to see how it all fits together. I also decided not to install it right now, as my panel is coming soon, and I’ll be working on that next. Once I’m done with the panel, and all associated wiring, I’ll come back to the engine, prop, and the cowling.

I started working on the spinner mounting plate, which needs some match drilling and cutting to get the two pieces aligned. I managed to get all the shaping done, and to spray a coat of primer on it.
