After I cleaned up the shop, I had a look at the engine. The airplane that engine spent its previous life in, the Cessna 172 Cutlass RG, is a 28v airplane. So I have a useless 28v alternator and a useless 28v starter. Maybe not useless, but certainly of no use to me; I’m going to run a 14v system. Maybe. What I don’t get is what’s going to be 12v and what’s going to be 14v and whether or not it matters. So another thing to puzzle out. The good news is, i’ll be able to keep my firewall penetrations to a minimum, because the MGL RDAC (the box all the sensor probes connect to) is mounted on the engine side, with one comm wire going back through the firewall to the EFIS. I’ll need to poke holes for the panel bus power and the control cables, but that should be it. I hope.

Up She Rises
2 hours.
Most of the time was spent cleaning the shop, after I drilled the WD-725’s to the forward frame and the aft channels, but what I really want to show off is this:
Canopy down.
Canopy Up!
Still clecoed, of course, but I took the opportunity to thoroughly clean the shop. I policed up all the clecoes that had rolled under the furniture, vacuumed behind everything, emptied the trash, and sorted out a couple of the messier tool drawers in the toolbox. I vacuumed out the plane and went over the shop with the vacuum again. The goal was to hav the workbench completely clear, because the next fun thing that happens is the Big Cut!
