We got our phenolic liners and casting tubes made by plastifab

They were used in the twelve 6" motors we made for the Myth Busters 'JATO 3'

I then recovered them from the wreckage, cleaned them up and reused some a
second time in this burn (starts at 1:30 into the video):

Subject: [AR] Larger size motor case liners
From: Daryle Dismukes <daryled@xxxxxxxxx>
Those of you who are working with fuel grains in the 150mm / 5.5-6 inch
diameter range, what are you using for your motor cases and liners? The
largest I've done before is 98mm, and I used as much off the shelf Aerotech
hardware as I could. Now I need to do something larger in a hurry at work
and I'm hoping to find a source of pre-made carbon phenolic tubes between
5.5 to 6 inches in diameter. Any sources or ideas? Other things to try?
