Almost there...
Forgive the questions, Lazylathe. I'm kind of an idiot when it comes to this sort of things. Will the Evo mouthpiece work on the Herbie without modification? Did you stick something on the end to make it fit Herbie's bowl?
No worries!!!
I used a bit of silicone tubing that fits over the barb and snugly inside the glass mouthpiece. Works really well!
