I was at a fly fishing trade show recently, and I came across something that I had not seen before. It was a machine that you could load a piece of wire (I think), put clumps of dubbing on the wire, turn it on, and you would get a piece of wire that was perfectly dubbed. I am pretty sure that I am remembering this correctly, but I have no idea what it actually was. It seemed to turn the wire and thereby "dub" the wire. Then the guy tied in the dubbed wire, wrapped it on the hook, whip finished with thread at the head, and was finished tying his fly. I must admit, I am relatively new to fly tying, but this seems like an incredible way to tie many dubbed flies (i.e. scuds). The machine was mainly made of wood but also had some mechanical parts. It was about 10-12 inches long. Has anybody seen anything like this? And if so, where can I get one?!
This is kind of what it looked like, but the one I saw was motorized and dubbed the wire VERY fast.
Thanks for the help y'all!
ALSO, what are these exactly used for? I'm sure I could come up with some applications for it, but why were these created? What was their original purpose?
