More on Engine Oil Cooling

It’s Deja Vu all over again. I swore that we wouldn’t fly with these soft aluminum tubes again, and here we are about to do it. So, a couple of things, we’ve studied carefully how you’re supposed to insure that your flares are good. Secondly, if we find that the larger hard tubing does give […]

More Cabin Heating from Engine Oil

Here are some pictures for you of the new heater installation. Here you can see the new duct that replaces the one from the NACA and accepts the air from the bilge fan. We still use the standard flapper valve to take the air to the keel or dump it overboard. In the keel we […]

Cabin Heating Improvements

No picutres yet, but Bob has been glassing in a flox flange below the flapper valve that seals off of the overboard hot air dump duct. This never quite sealed right, but we didn’t consider it a big deal when we had a ton of NACA air to supply. Now that we’ll only have bilge […]

Cabin Heat Test

Here you can see we’ve cleaned up the heater installation a bit, and removed the oil lines to the “standard” NACA location. We’re going to set up so we can recirc air through the cabin, to the heating element, and back to the cabin, or dump the heat overboard. I’m actually not sure how effective […]

Firewall Mounted Oil Cooler

The rear mounted oil cooler comes as a kit from the factory. After some playing around with the three pieces and looking at the pictures on the factory website, it becomes apparent how this goes together. Basically you drill a 4″ diameter hole in the cover-plate and install a ducting flange with pop rivets, then […]

Connecting Engine Oil Cabin Heating

Two runs of 1/2″ 3003 Aluminum tubing are run from the firewall up to the nose of the aircraft, and then covered in heat shrink tubing to add some insulation value to the line. At the aft end, the lines are installed with nuts and unions to a pre-made (by the factory) plate, and safety-wired. […]
