Backyard Rocketeers Keep the Solid Fuel Burning 334

Jamie Clay points out a New York Times article about one sticky wicket faced by members of the Tripoli Rocketry Association, whose members are some of the private citizens trying to bust into the space-launch business (or just having fun) by financing and building their own rockets. An excerpt: "On Tuesday, lawyers representing Tripoli and the National Association of Rocketry and officials of the firearms bureau will head to Federal District Court in Washington to resolve the seven-year-old dispute over the hobbyists' use of a flammable propellant, ammonium perchlorate composite, or APCP. The chemical is the main ingredient on the space shuttle's solid rocket boosters. ... The firearms bureau classifies APCP as an explosive and, amid post-Sept. 11 security concerns, requires that anyone who uses more than two ounces of propellant undergo federal background checks."

    I have some rocket friends that are into the high power stuff... It is not even the background check that bothers them, it is some of the insane storage requirements. To legally store more then a small amount, you must submit floor plans of where it is stored, and local authorities MUST have a key to the location, and have full rights to inspect the location at any time, as often as they want. So nevermind the local law enforcement or FBI wandering around your house at 2 in the morning, there is nothing you can do...

    Most of the people I know gave up at this point, or built small storage sheds that were up to code just to house their fuel which technically, according to the FBI, is not explosive anyway. (it burns rapidly, but does not explode, there IS a big difference actually)

      I came here to point out the same thing. Most rocketeers don't mind the background checks, in fact, I don't know anyone that oposes them. They are no more invasive than employers require these days.

      It's the storage requirements that basically block anyone from keeping any of the stuff. Not only are the storage requirements strict, so is the transport. Don't really expect to transport it in the back of your SUV. Obviously there are strict guidelines for storing it near high population areas, but that doesn't really affect hobbyists since they need wide open spaces anyway.

      Really, I don't think the strict rules are that bad. At least you can get the stuff, as it is rather dangerous, even if it just burns fast and hot.

        Yep. I live in Houston, TX and the city has decided that you need an explosive storage permit to keep any. And they won't give a permit to anyone in a residential area. (A club member found out after paying the non-refundable permit fee of over $200.

        Obviously there are strict guidelines for storing it near high population areas, but that doesn't really affect hobbyists since they need wide open spaces anyway.

        So where do you keep it if not at home? Look, the ATF people have refused to discuss any kind of compromise on this. They want it treated like all other low explosives, even though lab tests show that it's not an explosive.

      Well, if my neighbor's house catches on fire, it would be kinda nice if the fire department knew that x amount of explosives were stored in the house, so they could evacuate surrounding homes, etc. At the very least it could save a firefighter's life.

      Perhaps what is needed is an additional tier to the regulations, so a typical rocketeer could keep a "normal" amount of APCP on hand without quite as many requirements.

        The problem is that the composite propellant they regulate isn't an explosive. It just burns hot and fast. Homes have all kinds of items more dangerous to firefighters in them and no permit is needed, including: gasoline in cans, aerosol cans, propane bottles (I have 6 for my grill), insecticides, ammo for guns, etc.

        Many high-power rocketeers that I know are more than happy to build the storage sheds. In fact, if you talk to folks who have actually gone through the process, some of the local officials and fire marshalls have been helpful, and been willing to look into variances when appropriate, some are just anal and don't want anything to do with it. In other words, it's just like any other government process! =)

          You can legally posess 50lbs of gunpowder without any permit or inspections according to ATF regulations. 50lbs of gunpowder is a heck of a lot more dangerous than a few rocket motors.
    • In Australia there are similar restrictions if you want to keep a handgun at home. My brother-in-law had one set up for his gun collection but compliance was a pain so he switched to using the gun club's armoury, I have never heard of cops knocking on the door in the middle of the night to inspect a private armory.

      I personally couldn't be happier that the authorities demand a demonstration of responsibility from people with dangerous toys.

      Also the requirements aren't static ... ATF is currently working on rule changes that would require many users of explosives to rework their storage to meet more stringent requirements for bigger locks and such. For the explosives industry this is expensive for hobby rocketeers it can quickly become more expensive than its worth.

Any deviation from FAA limits requires a pre-approved awaiver of the restriction. So why do we need another government agency regulating us on top of that.

    I know some guys making really big rockets, and they are using ammonium nitrate and aluminum with a binder, mixed in a blender. Doubt this would ever detonate by accident, AN takes a really big hit (more than a blasting cap) to go in this combination. It might be getting harder to get, though.

    Yes, the background check is a pain (and in some cases I think you pay for it) but that requirement for a "magazine" is pretty stiff. It can't be in your house anyway, no worries there about being searched (the background check is worse anyway sometimes), but in a non-rural setting you're going to have a hard time finding a place "far enough away from people" to put one, and that is a requirement. I do some of this stuff here, in fairly small quantities, and had occaision to talk to the local BATFE guys about it. When they saw what I was doing they had no problem with it, is all I can say. Doesn't matter what the laws are if the cops are alright. Of course, you'd better have a nice big place to shoot nice big rockets anyway.

    Heck, it's legal to have quite a quantity of smokeless powder for reloading, and that is darn powerful stuff, and can be detonated at least in small quantities. This is just one of those silly things about ignorant lawmakers (some of whom are unelected) trying to CoverTheirAxx.

    These ridiculous restrictions on chemicals sounds familiar, I've run into the same thing in my trade, photographic printing.

    I work in antique photochemistry processes, and the chemicals I've used are now subject to regulation by the Department of Homeland Security and the Drug Enforcement Agency. Just last month, I was checking prices at the same supplier I've used for 30 years, and to reorder the same old chemicals, now I have to file DHS forms with the vendor, including a copy of my photo ID, the location where I will store the chemicals, a detailed description of the chemical formula I use, and a waiver allowing the DHS and DEA to inspect the records at will. I phoned the supplier and asked about these forms, and they said, "oh don't worry about it, we've only had DHS inspect the records 2 or 3 times." Oh I feel so much better after hearing that.

    So now I know why the processes I use have almost completely disappeared in the last few years. Nobody wants to subject themselves to scrutiny by the DHS just to make a few prints. The really stupid thing about this is, the chemicals on the restricted list aren't really the most dangerous ones, you can buy stuff from the same supplier that's way more hazardous without filing any paperwork.

We currently use ammonium perchlorate engines, and we do indeed have to deal with these issues, which prove quite onerous. For this reason, our propulsion team [pdx.edu] currently has as their primary project the development of a hybrid paraffin and liquid oxygen motor. Both of these components have no regulatory issues whatsoever: the paraffin wax came from a craft store, and the liquid oxygen came from a welding supply store (or with the right equipment, you could make it yourself). Their test-fires have gone quite well; in addition to testing paraffin/GOX, they've also test-fired salami/GOX, which actually provided more thrust than the paraffin prototype tested that particular day. :)

    That just leaves us having to deal with any restrictions on active guidance that get thrown our way, which we'll deal with when we finish our active-guidance prototype.
