Panel installation ongoing

Harnesses laid out for the first time. Not quite ready for installation, but soon…

IBBS installed atop remote Comm 2 radio.

Comm 2/IBBS angle supports seen from below. At the front, the angles are Prosealed to the firewall structure.

Lots of wiring neatening left to do here (obviously), but the Comm 2 radio has now been connected to its harness.

Not much a photo here, but it’s a quick shot of the glareshield cover sitting beneath the canopy. I’ve just affixed the glareshield edging and the Velcro patches for the cover.

The seats have finally been removed from their box! A very nice job done by Abby at Flightline. The carpets can be seen lurking in the background.

I’ve been wondering for over a year (since I built the fuselage forward floor area) about how a flat floor would be achieved with the longitudinal angle in place. Now I see – a very ingenious solution!

If you don’t already know the answer, keep wondering for another few weeks…

Right side wiring cleanup underway. Most of the delay on this side has been due to the lengthy process of deciding upon and executing a solution to the B&C regulator location conundrum.

Problem solved!

Back under the left side for some semi-final wiring cleanup.

The B&C regulator in place. It turned out (completely coincidentally!) that the bolts holding the Comm 2 radio’s forward edge to the support angles were an exact match, width-wise, for the regulator.

Ideally, I’d have used the center hole on each side of the regulator, but there was no way to do that and still fit my hand above it with a wrench. In practice, though, it’s fine; that puppy isn’t going anywhere.

Having finally received the proper 3-blade stripper and crimper for RG400, I set about installing the Comm 2 antenna cable.

Unfortunately, the antenna backplate’s center hole (around the connector) is just a tiny bit too small to allow the terminal to fully seat. I’ll have to remove the antenna tomorrow and open it up with a Unibit.

Oddly, the other side (for the Comm 1 radio) is fine. Weirdly non-standard, right? Van’s – what are ya gonna do? LOL

Firewall forward progress

P-mag ground wire now terminated and connected to an engine case bolt.

Right-side ignition lines and EGT wires neatened. Oil cooler SCAT duct installed along with manifold pressure hoses. Final connection to P-mag to be made after that last backup alternator nut is finally tightened once the special Snap-on tools arrive next week.

Panel component installation underway

Transponder installation underway. I fabricated the tray for the remote unit and will screw it to the underside of the panel and sub-panel flanges.

Lots of wires to get oriented and squared away, but nearly all of the connections (not including the stick-grips) have been made at this point. All of the wires that pass through the firewall have been so passed. I’m about ready to do the firesleeving of both firewall penetrations.

I moved my padded “nest” from the left side to the right in preparation for installing the remote Comm 2 box and the IBBS, as well as zip-tying all of the dangling wires on that side.

The remote Comm 2 can be seen here in the rack I fabbed for it. The IBBS will be mounted above it on a couple of span-wise plates.

Firewall forward components in place

Backup alternator to fuse wire version 2. Much better.

Starter solenoid and master relay wires in place. These were pretty tough to do, as my big hands aren’t overly compatible with this nearly inaccessible location on the firewall. Not much space between all of the engine mount tubes and lots of wires & fuel/oil lines in the way.
