For a great chum grinder--go to www.northerntool.com
They have the #32 meat grinders on sale right now for 34.99.This is a hand crank grinder.
I bought one a couple of years ago, mounted it on a board,went down to Dunkin Donuts and bought some plastic pails with lids,put some ice in a big cooler, went out and jigged up as many macks as I needed, (took a couple of trips), went home and ground all the chum I needed.I set the board accross a couple of saw horses and just set the pail down below and grind away.Best investment I've made in awhile.
These grinders come with a grinding disc with holes that are too small,so I sent to a company down in Winterville,NC at--www.fish-ng.com and they have any size disc you want. I like the 3/4 inch holes myself.
Hope this helps-- Happy grinding [img]/infopop/emoticons/icon_biggrin.gif[/img]
