Bob, I remember sitting down in our cramped temporary housing almost 4 years ago figuring out with paper-doll cutouts of the RV-10 how many support columns in my new basement would have to be replaced with trusses to create the necessary clear space. Sneaky! Paid big dividends in workshop comfort.

Bill,

Have you figured out what happened with the compressor? This one scares me since I have had the exact same compressor for 4 years, and of all the things in my shop, I probably worried the least about having issues with it. I'm now trying to remember to at least turn the power off to it so it doesn't cycle while I'm away. I know I should have been doing this anyway, but really other than draining it every few days, and an oil change after two years, I've just let it sit in the closet and do it's thing.

Thanks,
Lynn

I was in the shop riveting tonight when the compressor cycled and started squealing and groaning. I took my hearing pro off and walked over to the compressor closet when I heard and saw a POP and foot-tall flames began issuing from all the vent grilles in the motor. I unplugged the 220V, ran upstairs and fetched a dry chemical extinguisher and let fly, probably unnecessarily since the flames were just a couple inches tall by then. Acrid smoke and monoammonium phosphate dust are a bad combo in a confined space.

The compressor turns freely by hand, as does the motor, and the belt was not burnished anywhere. The motor will be going to a rebuild shop, while I hope that the compressor is not the culprit. It's full of clean oil, and has never given a moment's trouble in the 38 months I've owned it.

I guess I will revert to fiberglass work while this happens. I was on chapter 42, getting ready to stab the wings and do control alignment. Sad...

At least the house didn't burn down this time! The starting caps look fine and the thermal reset switch never popped. Strange

Not yet.

Things are moving slowly as I live an hour away from motor repair shops and work the same hours they're open. When I get it to a shop I'l see what burned up. The "why" is a different question, though I think a defect in the unloader valve is highly likely.

Default Hidden hinge oil door

Time for a project update. Here's my oil door going together, using ideas shamelessly gleaned right here in VAF.


Hidden hinge made with leftover elevator push tube stock


Hidden latch using hinge pin anchored in the inlet ramp.

Works like a charm. Due to stresses in the hinge parts, it even pops open an inch when unlatched without the need for a mousetrap spring on the hinge pin center, which I will add later for better cooling on the ground and to hold the door fully out of the way during dipstick operations.

Default Now that image posting has been made more direct

I might toss up a few more pics of progress as things move to the final 10 (read: 90) percent left to go.

Default Add a couple of collars

Bill, I would suggest adding a couple of collars to your oil door pull wire to limit travel. You can get them at any RC model store.

I have them on mine. It gives a positive feel for open and closed. It would be a real bummer to pull the wire too far and have to pull the cowling to re-thread the wire.

Good idea, Leo.

My door has a natural "pop" to it when the pin is pulled enough to disengage the locking hinge section - I was going to rely on operator savvy: stop pulling the pin when the door pops open. Maybe that's tempting fate
