I've been messing around the last few days puzzling out an oil cooler mount. I've got the main parts fabricated, but I'm still sorting out the details of a sliding door I want to have between the engine and the oil cooler. I plan to fly in the winter, and it gets pretty cold up here, but the temperatures can vary significantly from day to day. So I don't want to have some sort of cover over the oil cooler that I have to install or remove depending on the temperature. I want a sliding door that I can control from the cockpit to meter how much air gets to the oil cooler. I thought I had it all figured out until I noticed a bolt head that is in the way of where the door was to slide. So, back to the drawing board. I'll post some pictures once I get it figured out.

I had to spend a bunch of time today digging a big hole in the back yard. I think our septic tank may be full, so I had better get that sorted out before winter hits too hard.
