Installing the engine and more build.
The push rods, rocker arms, and new rocker shafts installed. Just need to check the dry lifter clearances and install the valve covers.
Starting to come together now.
2 of the cylinders installed.
Getting everything laid out to start installing the cylinders. They came with new pistons and rings already installed and fit. All that's left to do is pull the piston out far enough to get the new piston pin installed and push the cylinder onto the engine.
Putting an engine together.
Installing the generator and the oil screen housing and screen. At this point I went ahead and installed the engine on the airplane.
Accessory housing is on and everything is torqued down.
Installing the camshaft and crankshaft gears.
The crankshaft went .020" under on the main and rod journals. The camshaft was rejected so I had to buy an overhauled camshaft. 4 of the 8 lifter bodies were rejected due to spalding on the face. Sighhhhh, nothing money can't take care of.
Case halves togher. The string that is sticking out where the case halves meet together is silk thread. The sealant between the 2 halves is a combination of loctite 515, aviation permatex, and silk thread.
Installing the bearings and the thrust washers.
Getting the case halves cleaned up and ready to start putting together.
Connecting rods being installed.
I didn't really like how the covers turned out after the plating, so they also got primed and painted.
All of the external hardware along with the valve covers were sent off and "gold plated". This is not the right term, but they had some kind of plating process done and they look gold, so that's what I call it.
The spray coats on top of the wing.
I've been leaving these out, but these are the holes that had to be cut to remove the screws on the boittom of the wing for the fuel tank straps. The same process was done here as on the top of the wing as far as laying in a couple of small circular patches adn going through all the different coats.
The final coat of poly-spray has been applied and it is ready for the color coat of poly-tone.
This is the silver poly-spray. This is after 2 cross coats and some wet sanding.
This is after another coat of poly-brush. I have also taken an iron to any of the pinked edges that may be trying to curl up and fixed any imperfections with the iron. It is now ready for the silver coats of poly-spray.
Installing the fuel tank.
Sealing the fuel tank.
A light coat of primer over the bare aluminum and it's ready to put back in.
This is where the fuel tank was leaking. The stiffener that runs across the top is spotwelded to the tank and clear at the back the spot weld was pulled apart. The sealer is a 2 part fuel sealer.
This was a pressure gauge set up to pressure the tank to a couple psi and then make sure I don't lose any pressure.
