oil door flag or spring?
I've found that my oil door is easy to forget to fasten. By its nature, it lays closed when not latched, so it's easy to miss that it hasn't been latched.
I've thought about making some sort of spring-loaded flag that pops up and/or holds the door open when it's not latched. But it seems to me that surely someone else has already observed this problem and come up with a fix for it.
Has someone already done this? Is there a product on the market for it? Any suggestions for something that will cause the oil door to remain up, or a flag to pop out, when the door isn't latched?
thanks,
brian

Mine is spring by the use of the hidden hinge which incorporate a spring in that hinge. It is a very simple set up and can be done with any type hinge. It is so obvious that if I forget to close it, I should not be going flying.

Anyone have a picture of what these springs look like and where I can get one?

Or you can simply buy the torsion springs (McMaster has them) that fits your installation. I know they were selling extra spring with the hidden hinge but I can't remember who/where one can buy the exact part.

I have a Hartwell latch on the oil door of my RV-4:
One of my pre-taxi scans is left gas cap, oil door, right gas cap. It is very obvious from the cockpit if the door is not latched.

Another idea
Brian,
I was looking at the oil door hidden hinge and or adding a spring to my current setup, in the mean time, I built this:
Simple little wood block with a #2 phillips bit in the bottom to open the door. A slit is cut in the wood block to keep the door open in windy conditions. And of course it is painted bright orange so that I can see it!!

Steal one of the many plastic hair clips that your wife-daughter-girl friend might have lying around and take the spring out of it. Works great and if you keep your mouth shut it won't cost you anything.

clothes pin spring
Some great ideas here.
The torsion spring off of a clothes pin works.
