Sheeps casings were the first I used with my Vertical stuffer.
I found at first that they were a bit tight to get on the smallest tube, but when soaked overnight they would fit OK.
Once you get them on, its a dream to stuff them compared to the old moulinex - turn handle (avoiding overhanging cupboards
) and perfect sausages come out with no need to even touch the casings at all - I had a round stainless tray (about �1 from Tesco) that the filled skins would just push round as they filled, ending up like a giant Cumberland.
You can get away without bolting the stuffer down if you put it on a wooden base and cover the bottom with 'slip-proof' matting.
