I ordered casings from Waltons to try to make my own sausage and am having nothing but problems. First tried the stuffing horn with my weston grinder and could not even get the casing on the horn. Then I read that it is much easier if you have your own dedicated stuffer so I bought a 5 lb manual LEM stuffer. Still had a hell of a time getting the sheep casings onto the medium horn. (Why is there nothing on UTUBE showing how to load the casing onto the horn easily?) First off getting the end of the casing seperated is a bear. Anyway, finally got the casing on and filled the hopper of the stuffer only to immediatley have blowout after tear, blowout what have you. What the heck is the problem? I am totally frustrated!
