Meet the prototype drum carder. I was a little limited to the sizes of cogs etc due to the contents of the lego set.

I decided to gear the handle so that I could move it closer to the feed tray

Currently toying with the idea of making a three drum model. I will work on putting together the real thing this weekend. I'm trying to use materials I already have which should be interesting. Watch this space.
