More junk engines stuff

Bear with me, I can get a little carried away.

The two Babe Bees were fun to restore and rewarding with great compression and that wonderful Cox Pop! I know they will run, no challenge there so I put them on mounts.

The broken case Wen Mac, another story. I'm afraid the case break extends into the case far enough to compromise, but I'm going to try and run it anyway. I disassembled it and cleaned the gasket and robbed a needle off one of my other Wen's so we shall see.

Of the four, the postage stamp is the most interesting, not just for the engine but for the two mounts. The guy was a better metal worker than he was a carpenter. The aluminum mount is perfectly cut and the holes for the machine screws are perfectly aligned. To house a fuel tank I would think? The wood, not so. Looks like something that I would do, measured with a stick and cut with an axe.

Might have been mounted in a vice and ran by the looks of the indentations on the wood. I was going to toss the wood, but thought, why not! Went out to the garage scavenged the two sheet metal screws and put it back together as found. Well almost.

Did you glass bead blast the cases on the Bees ? I was thinking maybe the po had it mounted on a profile plane from the sale and pic , I had seen them on the Bay .

Yes, aluminum oxide. Looks real nice in person. Packerized like. I polished the drive washers, compliments the fuel tanks which were rough to begin with.

Still wondering about the shape of that aluminum, must have been for some sort of a fuel tank?

It looks like the right size for a rectangular Perfect 1/3 oz. fuel tank.
Smart placement for the tank?

Very interesting, and nice that you reassembled it as it was. If only the engines could talk and tell you their history!

I might have one of those tanks sosam. Might be located a little high.

And thanks Chancey, I think the same thing.

Made a stand for the postage stamp, darn thing kept toppling over on it's nose.

Used the cutoff from .049's nose.

Still have to clean up the slot a bit and sand off the finish, distress and stain with walnut to match.......or leave as it.

Be patient, I'll get over this tri-motor thing eventually.

I certainly hope NOT ! !! You still gotta fire-up all three engines and get 'er off the ground....with video of course. lol!

With the tank being high it will be hard to start, but after it is running it's like having a pressurized tank forcing the fuel without using a hopper tank.
Just make sure you have a big enough loop in the fuel line to hang below the engines needle valve.

I'm just trying to work up the courage to run those two outboard engines. Sad

When I test ran them on the bench I loosened the case screws and shook the left-over fuel out and may have moved the needles. What I need to do is bench run them again, put them right back on the plane and start them while warm. Really need my son here to help.

I'm trying to avoid drilling holes in the top wing and running control wires down to the needles.
