Jesse: I got my conversion parts. They don't come polished and ready to use. I spent 10 minutes with mineral spriits to clean the anti-rust stuff off, buffed the parts and waxed them with plain paste wax. They, the small metering screw, the cylinder and the keeper/plunger thing. Go together smoothly now.
The design is interesting: you have to loosen the keeper housing a couple of turns before you can pull the spring-loaded keeper. Tightening it centers the keeper in a hole in the metering screw's sleeve and locks it. Yes I can see why you got impatient with it....not the most pleasant on fingers. There is a hole drilled in the keeper shaft that would allow you to run a wire through it and make a pull loop.....that would make it easier, but not necessarily more pleasant on the fingers. Thinking...
I have decided that I need at least one more measuring screw to test this thing.
The drum is drilled for the large metering screw, so the small metering screw is inside a sleeve....that's how they get one drum to work with 2 sizes of metering screws.
I have reservations on the small metering screw....the sleeve's end doesn't match the drum perfectly at the cavity opening.....so it'll catch a few small powder kernals between the cavity and the sleeve and the cylinder.
When I get the test going I will show pictures of that in the coming new thread.
