Last night I had just finished a project in the workshop and decided to clean a few pipes I keep there. I had my drill bits at hand and decided to measure and compare the airways within the stem.
Here's what I found:
Comoy's 3 piece C era, a Peterson and Sav 320 made in the last 2 years feature a 3mm airway
My recent Mimmo pipe is drilled to 2.5mm
I was surprised to see the similarity in the first three. Just curious about your results with "main stream" pipe airways.
