When I visited Bill Sweetland I was interested in his equipment, but he had already sold it to the folks in Alaska. His advice to me was to not try to duplicate his process, because it was just too expensive. I took him at his word, although it didn't stop me from experimenting, using a high-temp press at Miss. State University. Got my degree there, and had access to the equipment when they weren't using it for something else.
Bill was a helluva nice guy, and gave me the full tour of his place. Our educations were similar, so we could communicate. We spent several hours discussing arrow shaft production and such.
