[RocketsNW] Casting Tubes etc

[Sareth Tes]

Hello EX'ers,

    I realize in the dark ages when one had to go through an apprenticeship that anyone wanting to learn to make their own rocket motors would go through a long process where the first five years they would haul chemicals from the various suppliers back to the shop of the master and then spend the next 5 rolling Casting tubes until they could do so perfectly followed by, If the Master thought they were worthy making nozzles. Once they had become suffucently skillful at that the Master might let them in on the secret and arcane formula's of the art. 

 

But it is now modern times!

 

All of this is leading up to the question of what are the better companies to buy Casting tubes from? and is the method of pouring the slug solid and then drilling better or is the method of using a Mandrel to set the core better?

 

Thanks

Ralph
