He should have everything you need.

Jeff from Loki Research 

and of course me. :-) (Randy @ARR) but mine are more specialty items
(casting tube and liner sets for long burn 54 & 75mm motors, Aerotech
compatible 38 & 54mm sets, etc).

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
