Has anyone ever made thier own engines? I don't have much experience
with model rockets, but have done some work with propellants and wish do
construct a model rocket and engines completely from scratch.  If anyone
can give me some tips on the construction of rockets or the engins
please do.

Hi Scott,  "While most of us use commercially manufactured engines for
cost and safety concerns, there are other groups of people who may be of
some help.  Try this website:

Fred, he managed to make a four-line post with almost every-
thing spelled properly (thier), one elided word, and one -
count 'em, one missing letter, which happened to be in "engine".
As usenet posts go, this one is better than most!

Hey Larry,

Did you know that Shred Vector supplied a pic of himself for whoZat?
Believe it or not the guy was willing to be photographed by the
WhoNoozCrew and now is memorialized on the internet. Check it out. Not a
word misspelled or a comma out of place either.

Well gee, thanks for pointing out my spelling errors.  I'm glad to know that you
are able to make good use of your time.

Scott heres my advice......DONT!   we have large problems with the BATF and
NAFTA, and that is with profeshionaly made engins. should one of yours go
bad and hurt you or worse a by stander it could produce BIG problems for the
NAR and TRIPOLEY.

If you aren't able to take enough care to use correct grammar and
spelling when trying to communicate, how careful will you be when it
comes to handling propellants?  

Attention to *all* the details is important, especially when you are
seeking information about energetic compounds.  The way you present
yourself here is the only indication anyone has about your level of
maturity or seriousness.  By not taking the time to proofread your
original message and then responding sarcastically only confirms my
suspicions; I don't think I want to be living down the block from you
when you decide to start mixing stuff.

Stick with commercially made motors for now; they're a lot cheaper than
the equipment, materials, licenses and permits you would need to obtain
to do it the right way.

There may be someplace where it is legal, but in most states I believe
you will run into the fireworks and explosives manufacturing laws.  

Let's see...they're not model rocket motors, since they are not being
manufactured by an entiry that adheres to all of the laws regulating
them, and they are not certified.  They are not high power rocket motors
for much the same reasons.  (If you want to call them model rocket
motors they would fall under NFPA 1125, "Manufacturing Operations for
Rocket Motors", which requires licensing, permits, accountability,
recordkeeping, etc., in addition to getting the proper DOT documents and
classifications to get them certified.)

Since they aren't model or high power rocket motors, they would probably
fall under NFPA 1124, "Manufacture, Transportation, and Storage of
Fireworks", which has even more stringent requirements, unless you can
find a way to get them recognized as amateur rocket motors, in which
case each state and locality has their own laws and regulations.

At any rate, I seriously doubt that *any* jurisdiction would allow the
making of rocket motors in residential areas.  If you have any doubts or
questions, check with your local Fire Marshal's office and police
department, and don't believe everything you hear from "some guy at
tripol".

If you want to build your own motors goto rec.pyrotechnics .
