I got the trommel working today, using an intermediary gear reduction
unit. I am going to exchange one of the pulleys tomorrow so as to get
a few more rpm, but it's working nicely, even if it is held together
temporarily with vise grips and bubblegum. Tomorrow, I'll start
welding it out, and take some pictures of the whole thing. I am
satisfied with the trommel, but not its performance. It takes too
long to take the husks off, maybe changing the pulley tomorrow will
improve it. Pecan handling and processing is turning into a lot of work.

Keep in mind that poly V belt drives can use a flat driven pulley when
the reduction is about 5:1 or greater so you might be able to run the
belt directly on your drum and just a poly V pulley on the motor which
are available with taper lock bushes cheaply from bearing suppliers.
I've done this on a few occasions and it works well.
