Wiring Jig

I am mounting the remaining components into the wiring jig so I can start in earnest on the wiring.

Here are the components mounted to the sub-panel.

Cockpit side: Left is iBox and AFS AOA unit. Right is backup battery and 2 fuse blocks for battery bus, and backup bus.

Work Catch Up Post

Even though I haven’t been able to post to the server I have been working. These photos will later be annotated to describe work done.

Propeller Options

Since it does not look like the CS prop will work, I put a request in to Catto Props to see if I could get a 3-blade Catto prop.

Catch Up

I missed a couple of days work on the plane due to consulting work and a local forest fire; which caused me to go into pet sitting mode (my daughter & family were evacuated).

So this is kind of a catch up post.

I received the bent new switch/control panel back from my son-in-law and it looks good. Besides layout changes, I added 1/4″ depth to the panel to give good visibility of the switches, etc. when sitting in the pilot seat.

One of my friends gave me a bad battery the same size as the backup battery I intend to use, so I can use it as a mockup to get a small battery box fabbed.

In the meantime, the 2 batteries I ordered came in.

The CS prop off of the twin Commanche showed up at the hangar and it is unlikely I could use it on an RV-6 as the hub extensions and hub size are way too large. I did read that 1 or 2 RV-4 builder have used this same prop on RV-4s but had to make significant modifications (which I don’t want to do). So I remain with a fixed pitch prop.

Propeller

I might have a chance to do a CS propeller. My engine is capable of it. Bill Betts has a good Hartzell CS prop, 2 blade I think, that is for an O320, 160 HP engine. Trying to get info on it so I can see if it would work.

I would also need a prop governor so I sized one to see if it would fit.

Old Engine Mount

I stripped all of the  ‘attachments’ off the old engine mount in preparation for inspection and refinishing. But in my opinion I think it is shot. It does not look straight across the bottom  to me but I will get other opinions and try to measure. In addition it had a small plate held on with 2 hose clamps. When I removed that I saw an area that had been rubbed with a huge gouge, big enough to be an appreciable part of the tubing wall thickness.

Engine/Engine Mount

Worked all morning to finish removing the engine mount, about an hour apiece on the 3 remaining vibration dampers. It is definitely not a one person job. I had to make two special tools, and one difficult bolt took 2 arms and 1 leg to get enough torque to remove, leaving just one leg to stand on.

But the negine mount is off now for inspection & refurbishing. I do have a brand new spare engine mount in the event there are any problems.

The engine with mount removed:

Then my friend Howard showed up & wanted me to fly to lunch with him (C210). We decided on Greeley with the storm coming in. KFNL was still clear but turned out Greeley was getting closed in fast. Initially after takeoff on the way back we stayed low to stay out of the clouds & ice until we got higher ceilings in the Loveland-Fort Collins area.

Engine/Mount

Took a photo of the rear of the engine for future reference. I am going to remove hoses & old engine mount from the engine for inspection and refinishing or replacement depending on outcome of inspection & will use this photo for parts location.

Well after 3.5 hours of solid work, here is where I’m at. All hoses, etc removed. They will need to be replaced anyways as the plumbing is fairly different for the RV-7 versus the RV-6. Removed the nose gear from the engine mount. One vibration damper removed, working on the second. There are 4 of these. For the non-pilot, the engine is mainly held to the airframe by the outer 4 bolts. Naturally these are very special bolts.
