Zenith 750 Cruzer Why do I have the need to make airplane building way more complicated than it needs to be? I know that the answer is the desire for perfection, but sometimes I drive myself nuts!

I've spent the last two days filling and sanding and filling and sanding....

But...it's ready to go. It looks like hell, but it's all smooth.

   
Zenith 750 Cruzer I need to cover the whole area in black electrical tape now. Electrical tape is better than duct tape for two reasons. One, it can conform to compound curves, and two, the exothermic action of the fiberglass melts the glue on duct tape and makes it hell to get off the aluminum. At least that's what Sam James says...
   
Zenith 750 Cruzer One little spot of touch up filler to sand and this side is ready.

It looks terrible, but it's actually all smooth. I sure hope the fiberglass fairing looks good when it's done.

Zenith 750 Cruzer Most of this engine work I did yesterday, but didn't have a chance to log it. All four EGT probes are installed.
   
Zenith 750 Cruzer I made a left and right mount for the fuel flow sensors. These are the same kind of mounts as shown in the UL Power HomeBuilt HELP video for the UL Power installation. The mounts don't come from Zenith or UL Power so I had to make my own. I used the aluminum cut out piece from the iPad mount in the instrument panel, cut them to size, and bent the two sides 90 degrees with my $30 Harbor Freight bending brake.

Now I need to remove them and paint them white. See, here again-if I wasn't such a perfectionist I wouldn't paint these parts, I'd be able to rivet them on now, install the sensors, and move on. But now I have to take it all apart, prime them and paint them. ARGH!!! But oh man will they look good white!

   
Zenith 750 Cruzer Notice I mounted this one on an angle. When the fuel line is hooked up on both ends, it flows on this angle so the fittings will line up perfectly. In this photo the fuel line is just sitting on top of the sensor.

In this pic, you can also see the fuel pressure sensor installed but not wired yet.

   
Zenith 750 Cruzer This is the cooling tube for the regulator/rectifier.
   
Zenith 750 Cruzer The oil temperature sensor is installed as well as this 'thing' that the oil filter mounts to. I could finish this all up and connect the lines but I don't have the correct size socket for the two blue fittings, or for the stud in the center.

I've also been spending a lot of time trying to design the electrical system. I think the most challenging part is just figuring out where to mount things. For example, I need a 30 AMP shunt that get mounted on the firewall. But I don't want to just pick a spot now and mount it because there's a lot of other things that still have to get mounted on the firewall and I'm not sure how they will all fit.

Inside the cockpit, I need to figure out where to mount the battery bus, the ground bus, and all the other parts. I also need to figure out what size wire to use on the different parts of the electrical system and need to order all of the various wire and terminal connectors. It's a lot of studying to figure everything out.
