I'll allow the Permatex "Right Stuff" used to seal the adapter to the block to set up for a day or so. Then fire it up and see what the oil pressure is.

Oil Pressure Gauge
I decided that the oil switch (however reliable on the bench) is not sufficient for determining what's going on with the oil pressure. Thanks to Tiger Tom, we made an adapter out of a 1/8" Tee and cut off drilled 7/16" bolt. The switch now hangs under the spark cover, and the spark cover has been moved outward by 1/2"... this accommodates the 3/16" copper line that runs to a pressure gauge out of a Sunbeam Alpine (So generously donated by Tiger Tom). I should just be able to glance down between my leg and the seat to see the gauge.

Clutch and push rod
Since I don't have any copper washers in my workshop to fit the sump pan, I started working on the clutch.
The thrower seems to work good, so I put the flywheel back on. The clutch lining was full of oil and grease, so I tried to wash that out as best I could with brake cleaner.
The big project was creating the new push rod. My workmate Mike had already made the pushrod receiver that I tack welded to the square hole in the pressure plate. I wanted to make sure it wasn't going to come out and get jammed in the shaft somehow, hence the tack weld. It shouldn't, but I didn't want to chance it, and I didn't want it to start turning either, since the shaft into the pressure plate is round instead of square.
I took Wilhelm's full length measurement (225mm) from the surface of the pressure plate to the end of the rod and cut the 1/4" drill rod that had bought to fit. I squared up the ends in the lathe, gave them a slight chamfer and then polished them up to a high shine. Drill rod (aka silver steel) is fairly hard so that took a while. I test fit it in the gearbox and it looks right. I can drop the rod in after the gearbox is mated to the engine.
I decieded against a ball bearing at the clutch end for now. I can always cut the drill rod more and fit the ball bearing later if I think its not working right.
The next fun part will be to compress the clutch springs enough to put the nuts on. I guess a few clamps around the flywheel and pressure plate may do the trick?
