It's interesting that you ask that question. When the Condor project
died most of
the members of the team went their own ways in terms of hobbies, and while I'm
not running 6" motor's any more, in fact don't have a running motor at the
present time as I gave my last 1.5" version to the local high school,
I still dabble
with peroxide motors.
Presently, If I need peroxide I buy 22.5l carboys of 35%, the highest legal %
allowed in Canada at the present time with out the red tape hassle. I put it
through an Ion filter to get rid of some of the stabilizers and then vacuum
sparge it to about 88%. For me it was never the motors that was the problem
it's the catalyst that we have been using and I have been searching for a way
to get around the silver poisoning that so often happened to my cat packs.
I've also been looking into other catalysts, as well as additives to
the peroxide
for better performance.
When we had full staff on the project we could produce about 25 liters a week
( roughly an Imp. gallon a day ) using the 50% base stock we were able to
purchase at that time.
Had we flown the Condor we had an source in the US for both the launch
site and the peroxide which at this time shall remain un-named.

Just curious. I remember former Armadillo gave up on 80-90 % peroxide as a
propellant because they reported that unexpectedly, they found no more
supplier. As considerable batches were required for their tests and
launches, they had wisely decided to avoid the hassle to distill it
themselves. Realizing such a mini plant of their own for it takes years to
design from scratch and build.
Big companies "responsible care" policy prohibits selling HTP to rocket
amateurs. So where do you buy or intend to buy your HTP at present, Robert?
Monroe?

One thing your going to have to be prepared for, at least with using silver
as the catalyst, in my experience no two runs are exactly the same. There is
a little bit of an art in getting a clean run and with silver, temperature,
RH and even barometric pressure can play a role in getting a good clean run.
