After hearing the "Session" when Fred Francis of Monster Brewing Hardware was the guest (mid last year), I contacted him to see if he needed some assistance in designing a hopper for his product line (in the show he mentioned that he didn't have a hopper to offer). Well over a year later (no real rush on Monster's part), the prototypes are in, and Fred will soon be selling these hoppers on his site. As part of the payment, I now have one of his 2.00" diam, 3-roller versions, and after building a base and adding a motor, I love this set-up. I will post pictures of the finsihed assembly in the next few days. If anyone is interested in drawings of the base, let me know, and I will send you pfds. I will also share any of the details on the sheave sizes used, or any other information desired.
Take care,

One "lesson learned" is the motor I purchased (on eBay) isn't capacitor start, so I do need need to start the motor before filling the hopper (the mark on my finger nail has almost grown out from an impact which occured when I tried to spin the large sheave in an attempt to get the mill spinning).
