MM tenon diameter

[drennan]

Very quick question
Is the tenon diameter of all MM corn cobs the same?
I've got a pair of Great Danes and a pair of Washingtons and they're coming in at 8.8 cm. With the Pony Express and Mizzou being smaller pipes do they have the 8.8 cm diameter tenon?
Thanks

Replace the bit.
Living outside of the US the forever stems are a little bit too much money and they will be alot of hassle with import duty and collecting from the post office, red tape is a favourite of the French! So, I was wondering if I can pick something similar up inside of Europe. I'm also thinking about picking up some of the pony express pipes and two birds one stone and all

I'd be looking to buy one off ebay.

I have several MM and I believe the tenon on the Mizzou is smaller, check with Scott at Aristocob.com

The filtered pipes have a larger diameter than the non-filtered. But within those distinctions, the hole should be a uniform size, due to the machine manufacturing process. FWIW, a Forever Stem will always fit a new, unused MM filtered cob.
I don't work for 'em, just use the products.
