Here is a story of snatching defeat from the jaws of victory. As noted in the garage sale thread, I won a
bunch of planes in UK based auctions. This 311 was the most interesting, so I started cleaning it last night. Definitely a user grade tool, nickel is flaked / worn off in places, dings here and there, a bit stained. Bit of research shows its probably pre WWII, as they stopped nickel plating them at that time. The plane was dirty, and missing a blade, so I took a chance, and bought a Ray Iles blade for it from the UK, thinking this would improve the plane.
As received.
I took all the pieces apart, derusted things, polished the nickel with Simichrome, and oiled the screws. Went to put the blade in, and the cap would not fit into the slots in the body. Took at look at the boss that the lock screw threads into, the casting was kinda wonky, cleaned that up, still not going.
Bit more cleanup here and there, still nothing. Remembered I had a Record 077a, grabbed that, the lock screw was the same, but the blade was substantially thinner.
****, back to the drawing board. The Ray Iles blade is a hair wider than the 077a blade, and did not drop into the body. there is essentially zero slop in the 311 body with the Iles blade, but the 077a blade wiggles a bit. More dicking around tonight.
Here it is cleaned up. Somewhere I also have a Preston 311 nose piece, (found in original packaging at an estate sale, but could not find the plane), to turn it back into a Record 077

. Probably will never use it, but will find it and see if it fits, as the parts were numbered and hand fit it appears.
