The "barrel to support the system" means who would be manufacturing the barrels. I do not bore freak inserts, so I can not bore barrels 9" deep. There is a possibility that tjd10684 might be able to, but you would need to ask him.
I am currently shopping around for the necessary parts to build a new machine. The main piece is looking to be around $1250! Then there are all of the support pieces I would need to make or purchase. This would not be a cheap investment... Plus I would need to locate more shop space... My walk in closet of a shop is full.
