When we bought Jim Rossen's stuff, we got a bunch of casting tubes for 38, 54 and 75mm motors. There were a few liners, but mostly for 54mm. We would like to buy good quality liners. Anybody got a source?

John Lyngdal used to be a good source for the Kosdon/AMW/Loki sized case and casting liners. I thought Loki sold them also.
Check out Always Ready Rocketry, they sell liners and casting tube sets.

I don't know John Lyngdal - anybody have contact info?
Loki liners are great....but he sells sets.....and his store is down.
He’s the Vice President of NAR, chair of NAR S&T, a really good guy, and goes by Johnly on TRF. You should be able to send him a PM using his TRF name.
Thank you, I'll pm him
John Lyngdal doesn't sell liner/casting tubes sets anymore.
If you only need liners, it will be difficult to match casting tubes to someone else's liners. They are typically made as a set with close tolerances.
RCS/AT has liners for 75mm, but they are expensive and may not match the casting tubes you have. The ID of the RCS liners may not fit well on the liner overlap for AMW/Loki/etc closures.
It is good to know that John Lyngdal no longer provides these.
You might want to see what Paramount Tube would charge for a batch. Youd have to measure the OD of your casting tube and the ID of your cases and provide a set of tolerances. Ive never ordered anything from them, but I recall their name from similar past discussions.

Loki has sold liners separate from casting tubes before. Give them a call, might be able to do something even with the web-store down.
I believe all the tubes Rosson used were AMW/Kosdon East size.
Kosdon 38 and Loki 38 are not the same size.Yes, the liners fit the Loki cases too. All the cases we got from Jim are gold Kosden cases.
Kosdon 38 and Loki 38 are not the same size.
