[RocketsNW] Casting Tubes etc

[Always Ready Rocketry]

Thanx for the plug Mike. :-)  It does ok, AMW uses it in their classic
reloads and some ProX.  It turns into a pretty crispy critter with some of
AMW's hot loads, but fares well otherwise.  Some of the driving force for
using it was made by Paul Robinson at the time as an alternative cost saving
measure of having to replace brittle phenolic liners that were damaged in
shipment or somehow got cracked.  His logic was that it would save AMW money
even though it cost more for pure vulcanized fiber due to that.  We fired
some motors with Blue Tube liners when he came to visit Tripoli Tampa.  That
was the last time I saw him in person before his passing. 

 

I have a few on hand, but my specialty sets are standard phenolic. The long
burn sets fit Loki, Gorilla, etc and the standard sets are for AT.  They are
a double phenolic with a kraft casting tube.  The boys in Texas tried
something like an M500.  It burned for about 12-14 seconds.  It was pretty
much toast but the motor was ok.  I didn't design them for anymore than 8 to
10 seconds but you could probably push to 12 with a lower temp formulation.

I've heard that the Blue Tube has been holding up well for long burn and
high metals.

 

Last I heard, Loki was buying liners from John, so probably doesn't make
sense for John to ship them to Jeff so that Jeff can ship them back to PDX.

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).
