Its finally here. We have added gears to the already successful MM-3 to create the new MM-3G. Basically a scaled down version of the already famous MM-3ProG. This mill is NOT suitable for commercial applications including brew shops or commercial breweries. For commercial applications look at our Pro series mills.DO NOT run this mill backwards under any circumstances, you MUST turn the drive shaft ONLY clockwise to feed grain down into the gap. The drive shaft spins one top roller that drives the other top roller through a set of alloy steel gears. Grain from the top fixed gap is force fed to the adjustable gap between the main drive roller and the bottom third roller. Super reliable feeding is now a given for your hard core homebrew operation. The most advanced in our line of 3-Roller Home Brewing Monster Mills, The MM-3G is a further upgrade of our already successful MM-3. The MM-3G comes standard with two 1215 alloy steel gears driving two 1.5" diameter 1144 alloy steel rollers, with a third idler roller providing a second crush through an adjustable gap, solid 303 stainless steel knobs, as well as the 1/2" drive shaft with three flats for drill drive. The rollers are 6" long just like all our home brewing mills. With all the great features of our already popular MM-3, but with gears for positive feeding. The MM-3G crushes all your grain twice, with one pass through the mill. It starts with a preliminary crush through the initial fixed gap of 0.070” between the top two rollers, and then ends with a pass through the adjustable second gap (0.028->0.055) between the drive shaft roller, and the bottom third roller. The initial pass slightly flattens the grain, and gets it ready for the next crush, that breaks apart the grains and loosens the starch with minimal husk damage.

The MM-3G consists of 6061 aluminum block frames with three 6" long 1.5" diameter 1144 alloy steel rollers riding on Oilite™ oil impregnated bronze bushings, while the third idler roller rides in bushings that are offset mounted in an adjustable knob. The stainless steel knob is held in a fixed position by thumbscrew that you can loosen to adjust the mill. This system provides an adjustment range of .070". The knobs are turned from solid 303 stainless steel barstock for excellent durability. The skirt flange has a small cookie bite aligned with the eccentric offset that allows you to know how your offset adjustment is aligned. They have additional slots for a positive grip. For the rollers we use a superior grade of steel that is much harder (1144 alloy) than what is found on most comparable products. The drive shaft, and all the axles are integral to the roller rather than screwed into the ends. All the axles have minimal freeplay in the bushings for long lasting reliable life. This mill comes standard with the 1/2" drive shaft. We recommend a name brand corded 1/2" drill to turn this mill. Wimpy house special weak drills will release the smoke from the load. Suitable for the most discriminating serious hard core home brewer that wants the very best, the MM-3G is our flagship homebrewer model, the best of the best.

We highly recommend that you purchase our base and hopper. All current bases come standard with precision drilled alignment holes, dowel pins, and matching holes in all our Pro Frames, as well as the smaller MM-3 mill. To take advantage of this feature, you need to purchase our base and hopper along with your mill for precision frame alignment, and superior roller motion. You'll also need a high quality corded drill to drive this beast. We recommend a 1/2" drive name brand corded drill. Please note that the larger shaft will require the larger 1/2" drive drill, as the more common 3/8" chuck won't accommodate the larger shaft. Our hand crank does NOT fit this mill as supplied, nor is it recommended for any of our Pro series mills.

This mill will NOT mill corn and doesn't work well with rye by itself. It is designed for barley and wheat malt, and un-malted wheat. For corn see the 2Pro, or the 2ProPD.

Greatest toy for GSD!
My German Shepherd LOVES LOVES LOVES this thing. I’ve purchased about 5 of them, not because they don’t last (they do), but so we can have them everywhere (one in each car, the backyard, the front yard, the house…). The string makes them so easy to throw far and you don’t have to handle a sloppy foamy tennis ball. And it’s great for playing a little tug. All in all, a winner of a product!

Good Toy Reward for Training

A great non-food reward for dog training and play! It’s the perfect size for my German Shepherd and the tie makes it easy to carry and play tug. It’s also been very durable for her sharp teeth!

Didn’t last long

One of my puppies chewed the rope apart within an hour. They still have one of the balls and play with it often.

Good for playing tug of war, but better with a knotted handle
Size: Medium, Size: Medium
Strong and durable rope ball. I use it to play tug with my Doberman Pinscher -- at least until she decides that she's taking it, then she does!! The size is good, list of price is a good value for two, and my dog has a lot of fun with it. As you can see in the picture, there was not a knotted handle at the end. I was never a boy scout and don't know my knots and so anything I try to tie comes apart when we start playing. It would be nice if it came as it looked in the listing: with a knotted loop at the end.
