Bob's write up made this a fun little project, now easily accessed while hidden away under a rear seat.

The thread started with Bob N. identifying the lacing we should be using. Coincidentally I had already purchased that EBay offering. This morning the seller wrote

The instrument panel is a single piece with a 90 degree bend, the bend forming a shelf on top of the leg holes. (What's the technical term for &quo ...

I have been working on a transponder antenna for a fiberglass airplane (Cozy IV). I tried thin copper sheet, then copper flashing. I hated the weight of the first one I built (and the Frankenstein l ...

"I used LibreOffice Draw to make my wiring diagrams. It worked but was pretty time-consuming."

John –

Thanks for sharing the several documents. I’m building a Cozy IV, and about to start the plumbing and wiring, planning on an SDS system. This should be darn helpful in thinking throug ...
