Right Rudder Tools

I'm Tom. I fly a 1979 Piper Warrior that I own with two other guys — we went in on it together, which means we also split the maintenance, and
that's really how this started.

I've been flying about five years and got my PPL in January of 2025. After our last oil change, standing there with a wad of paper towels in one hand and a plastic grocery bag taped under the filter with the other, I decided there had to be a better way to do this than hoping.

If you've done it, you know the routine. You stuff whatever's handy under the filter, crack it loose, and then spend the next twenty minutes cleaning oil off the inside of the cowling anyway.

So I built SPILLBILL. It slides over the filter before you touch it, reaches forward under the adapter where the oil actually comes off, and
drains out a hose into whatever container you've got on the ground. No puncturing the filter. No bags. No towels.

It took more revisions than I'd like to admit. The first version didn't
clear an engine hose. The one after that fit but wouldn't stay put. The one you can buy today is the result of a lot of test fits on a Lycoming O-360 with the cowling off and a flashlight in my teeth.

I design these, print them, and pack every box myself, here in the Hudson Valley. If something doesn't fit your airplane, email me and tell me what got in the way — that's genuinely how this stuff will get better, and I'd rather hear it than not.

Keep an eye out for other cool tools here!
