Meat Grinder Jerky Shooter/Gun attachment

Cabelas has a great jerky slicer for on the end of you motor I think they are on sale now for 160.00 these are for whole muscle meat.

Lem has this product that you change the plate on the output to do patties, strips or sticks from ground meat.

yeah, I've seen that one and another variation of it. But I guess I really don't understand how it works. I think you shoot the jerky out on the wax paper and then transfer it to your smoking rack? Seems like a lot of unneccesary steps. Anyone ever used this or have any other ideas?

Thanks.

OK, just a follow up for everyone. I bought the LEM jerky maker, round snack stick maker, and patty maker. When I opened the box, it appeared to be a real nice all alumininum construction accessory for my ginder. But, it did not funtion well for making the jerky strips. Simply piled the meat up on the paper and if you tried to pull the paper along to help it, it would not help. Also, the strips were inconsistent with each other. IN other words, not all the jerky stips would come out at the same speed or some would and others would not.

Just fyi for anyone looking into it. I returned it.
