So as usual I looked around for an alternative cheap source for a homemade grinder, and found a pretty nice 3 piece at a time paper shredder that is fairly heavy built.
I brought it back to work, disassembled, removed the photosensing eyes, and cut out the entry port to a manageable size of 2"x 7" , and then made a hopper out of some scrap sheetmetal.
I attatched the hopper to the top and proceeded to test the unit with some coffee beans that were left over from the burlap sacks that the local coffee plant had just gave me .
by the way the nice lady in the office there gave me 10 full size burlap sacks and told me I could come back and get as many as I needed , because they just throw them away.
The new unit which I am either going to call the shrinder or the gredder
worked flawlessly, so I brought it home to test on some more fomiddable opponents and then ran 10 lbs. of feed corn through her and much to my amazement she did an awesome job, a good coarse grind about 3 to 4 pieces per kernel when ran through one time.
Now I know this is by far no commercial outfit , and may not last that long, but for $3.99 and about 1 hour of my time I am very sassafied
with my new toy
