@TinCupTom I can’t confirm that it works with a Cabelas brand stuffer but what I can do is give you the OD of the back side of the flange of our stuffing tubes which is 2 - 1/16th of an inch, they are all the same for all Walton’s sizes of stuffing tubes. So if you measure the flange on one of your stuffing tubes and it is the same then you “should” be able to use it. I’m not sure what the tolerance for variability would be here but I would have to imagine there is some allowance for error, so I’d guess if you were 2 inches heavy (less than a 1/6th of an inch) that it would work! Yes, the diameter it mentioned was the OD. I’m not sure about the plastic piece but the ID of our 10mm stuffing tube is 5/16th of an inch, if that helps? Now, if you are wanting to make 19mm (that’s the size I recommend by the way!) then you don’t need to use a 10mm stuffing tube, a 12mm should work fine for 19mm. Unless maybe yours came with a 10mm and the next size up is 20 or something? If that is the case then a 10mm will still work just make sure you are holding the casing onto the tube so it actually fills all the way up!
