I’m flying a 152mm 2 grain motor in a couple weeks, first tested years ago.
Case is 6061-t6, liner is cardboard wrapped with 1/16”epdm sheet. I can’t
recall ever seeing phenolic liners in the 6”size. Would have to be a custom
item.

Cases--which are also the airframe--are 6061-T6; liner is cast in place EPDM.
Grain is a center burning finocyl, also cast in place.

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?
