Model Forum / General / Rockets / June 2004

I was interested in developing my own motors, but don't want to just
"wing it" and end up minus 4 fingers.  Are there any good books,
documents, websites, mil-specs, or literature that covers various
different propellant formulations and correct methods to process them?

I have some Aerotech AP reloads (nothing over "F") that are about 8 years
old.
Junk?
I may donate them to the local Tripoli club in San Diego if they are still

If you want to check out a little good PR. Here is my contribution:

I was wondering if anyone knew of any organized club/group flying
rockets around the Ithaca, NY (Cornell) area?  I used to fly
everything from Estes "A" rockets up to "F" and "G" powered rockets in
HS.  I still have most of them even though I'm now in graduate school,

I've decided to get into telemetry as my rockets are going higher and farther.
GPSflight is intriging but I want something small that will fit into a 29mm
tube.  
Which is better...Walston or Rockethunter?  I'm looking for ease of use,

This is way off topic but kinda cool.  From what I understand it was a
several year project.

I put together a J420R 38mm 6grain AT RMS this evening getting ready for
tomorrow's launch.
While I have seen many engines have a gap in the grains to the end closure,
that allow them to move back and forth in the case, this gap was exactly

Do any of you know where I can find a transition section to reduce a
standard LOC 5.5 inch tube to a standard LOC 4 inch tube (reasonably
priced)?  Balsa Machining can't make one for me and I'm very nervous
about the styrofoam one I tried to make.

Found these at WalMart today.  They are motion-activated lights that can
screw into tire stems.  But who'd want to do that?

They look about the right size to fit into BT-5 tubing for night launch nose

    I've returned to this forum after a few years, and I've been reading posts
for several weeks now. I'm a triple BAR, counting this time, my last major
activity was in the 80's. Is the BP engine end of the hobby as dead as this
forum makes it seem? Is there ssome other newsgroup ...

Well, we're barely a week away from LDRS 23, a good time to
remind everyone that an event of this magnitude requires the
assistance of range duty volunteers.  If you can spare a couple
of hours to volunteer for a range duty shift, you'll find that

anyone build one, much less use it for certing level 2?

Anyone a good feel (or website) for composite tube thickness for various
materials over various diameters?  Strictly composite, not cardboard
reinforcement.
Thanks,
