I have a guide series 15lb stuffer, and from research here I see the FDick 3/8 tube from Butcher Packer fits. Unfortunately they have been out of stock for a few weeks now. I have the means of making my own out of stainless steel tubing, but have a few questions for anyone that already has a SS 3/8 tube. If you have a Caliper handy, could you measure the wall thickness on your tube, so i know what thickness SS tube to order? Also is the outside diameter 3/8 or is this measurement inside diameter? Thanks for your help, I have seen the threads on here where people show off their homemade tubes, but I cant seem to find this information. Mine came with all plastic tubes so I have no idea what thickness to make them out of. Any Idea what grade SS to use?
