I know Rickbin built his years ago, and the reamer that his smith used came and wetn (and maybe was recovered)

Did any one else every build one of these? how successful was it? what sort of problems did you encounter?

The big one, FOR THE LOVE OF GOD, does any one have a reamer?

I've got a print from PTG, but between internet reviews and my gunsmiths advice, I won't be having them make the reamer for me.
