Another 12-guage project...

i know where you got that idea, they should fly quite well, until they melt, have you seen nichropulse rockets, sugar fuel/ shotgun shell?

 

Dan.

[brimstoned]

I have not used sugar mix as a propellent yet, I do recall you mentioning it in shotshells in a previous post.

I'll try to get a clip the flight today. A prototype with no header flew quite well yesterday morning!

[brimstoned]

Ack...end blow out and CATO...I think using the hollow tube to ram instead of a solid dowel(the rocket that flew) may have been the problem.

Back to the bench...

 

 

Please forgive the shoddy camera work, I'll get more practice!

[brimstoned]

Success!

 

[shagaKahn]

this looks fun as hell. Could you post a tutorial? Or at least a brief description of your steps and what you used for fuel?

 

Would love to try this.

 

Thanx!

Basically, I removed the spent primer and covered the hole with AL tape; then rammed the case 1/2 full of meal. topped with paper and 1/4 " of hot glue. When ready, the tape is pierced with a bamboo skewer and fuse inserted.

A 3/8" tube fits well in a 20 gauge. If you replaced the shot and the wad you could fire it out of it. A small powder charge could send the rocket out of the barrel, it would ignite it. You could use a jet stabilized rocket so it won’t go out of control. The question is not “can it be done” it is “ will the batfe lock me up for doing it”.

I've put together comets like that to launch from a 1951 mil-spec flare gun...they work.

[TheSidewinder]

Someone in the WPAG a few years back used spent 12-gauge shells and made them into APCP rockets. They worked surprisingly well.

[pyroshell]

So would it be legal to fire a rocket from a shot gun? or will the batfe cal it a "DD"?

[Bobosan]

Here is the USC 18, section 921 abreviated from the ATF federal firearms regulations reference guide (aka the "green" book).

 

 

 

(a) As used in this chapter -

 

(1) The term "person" and the term "whoever" include any

individual, corporation, company, association, firm, partnership,

society, or joint stock company.

 

(2) The term "interstate or foreign commerce" includes commerce

between any place in a State and any place outside of that State,

or within any possession of the United States (not including the

Canal Zone) or the District of Columbia, but such term does not

include commerce between places within the same State but through

any place outside of that State. The term "State" includes the

District of Columbia, the Commonwealth of Puerto Rico, and the

possessions of the United States (not including the Canal Zone).

 

(3) The term "firearm" means

(A) any weapon (including a starter

gun) which will or is designed to or may readily be converted to

expel a projectile by the action of an explosive;

(B the frame or receiver of any such weapon;

(C any firearm muffler or firearm silencer; or

(D) any destructive device. Such term does not include

an antique firearm.

 

(4) The term "destructive device" means -

(A) any explosive, incendiary, or poison gas -

(i) bomb,

(ii) grenade,

(iii) rocket having a propellant charge of more than four

ounces,

(iv) missile having an explosive or incendiary charge of more

than one-quarter ounce,

(v) mine, or

(vi) device similar to any of the devices described in the

preceding clauses;

 

(B any type of weapon (other than a shotgun or a shotgun shell

which the Attorney General finds is generally recognized as

particularly suitable for sporting purposes) by whatever name

known which will, or which may be readily converted to, expel a

projectile by the action of an explosive or other propellant, and

which has any barrel with a bore of more than one-half inch in

diameter; and

 

(C any combination of parts either designed or intended for

use in converting any device into any destructive device

described in subparagraph (A) or (B and from which a destructive

device may be readily assembled.

 

The term "destructive device" shall not include any device which is

neither designed nor redesigned for use as a weapon; any device,

although originally designed for use as a weapon, which is

redesigned for use as a signaling, pyrotechnic, line throwing,

safety, or similar device; surplus ordnance sold, loaned, or given

by the Secretary of the Army pursuant to the provisions of section

4684(2), 4685, or 4686 of title 10; or any other device which the

Attorney General finds is not likely to be used as a weapon, is an

antique, or is a rifle which the owner intends to use solely for

sporting, recreational or cultural purposes.

 

(5) The term "shotgun" means a weapon designed or redesigned,

made or remade, and intended to be fired from the shoulder and

designed or redesigned and made or remade to use the energy of an

explosive to fire through a smooth bore either a number of ball

shot or a single projectile for each single pull of the trigger.

Someone in the WPAG a few years back used spent 12-gauge shells and made them into APCP rockets. They worked surprisingly well.

 

Do you know if he just cast the fuel into the casing or used inhibited grains?

[TheSidewinder]

It's been so long I can't remember for sure what he did, but I believe he said he used an APCP formula variant that's nearly dry once properly mixed, and he pressed them very lightly. The primer hole was the nozzle, and he just crimped the shell closed over a thin top wad once filled. Also seem to recall he used a home-made spindle inserted into the primer hole.

 

Somewhere around here I have a formula very similar to that, which someone gave me at the PGI in..... oh lord.... 2006?

Looks like this is a fresh topic. I just got a pound of AP from Skylighter, and besides some rubber (Parlon) stars, I want to make some APCP fuel to experiment with. First experiment will be the silicone II blue strobe formula, but I wanted to read what locals had to say about their own AP rocket experiments. The reference to 12 ga shells caught my eye, as I've had fun using BP in an end burner with a wooden nozzle to make 12 Ga stick stabilized rockets. Tons of fun, as are .410 gauge BP rockets.
