Stuffer tube for 16-19mm collagen casings

[yogi]

Hello!

I just made 85lbs of snack stix using my 8qt Enterprise stuffer using 16mm collagen casings.
I have a LEM 3/8" stuffer tube, and a reducing gear on my stuffer to make it all work well.
My question is this: Does anyone know if anyone makes a NARROWER stuffing tube?
The 3/8" LEM is 7/16" OD, and the 'sticks' of even 19mm collagen casings don't fit on the
tube unless you open them up and put them on 'inch by inch' (ie: just like you have to do with a
hog or sheep casing). If I use a 21mm collagen casing, I can put the whole stick on, but then
my snack sticks are fatter than I really want. I prefer a 16mm casing, but would go as high as
a 19mm if necessary. I am basically looking for a stuffing tube with a 3/8" OD!

Thanks for any help or advice!
