Honey oil with galvanized steel?

I'm pretty sure model rocket engines used to be designed around chlorates/metallic reducers.. I"m wondering if restrictions are growing on those, because ironically black-powder would probably pose more danger in a rocket engine..

In anycase, I'm actually really surprised I'm alive today given the number of idiot close calls we had as kids playing with explosives, and the irony is, the closest calls occurred when we were playing with seemingly less dangerous things, or just doing prep-work..
If there is any tip I can give to somebody too eager to play, if your bang doesn't happen just walk the fuck away for atleast an hour, but stay nearby to keep others away.. DO NOT APPROACH IT!!

im not sure if it is black powder in them but it looks and burns like it. and the estes model rocket engines you can get at any hobby store up to class C.


yea shrapnel doesnt play games... thats why my pipe bomb days are over. im glad i have my hands.

hah.. this thread really went off topic.

Okay, BACK ON TOPIC, lol, here's the scoop on Butane -vs- Galvanized Steel.

IT'S PERFECTLY FINE TO USE GALVANIZED PIPE IN YOUR HONEY OIL EXTRACTION APPARATUS!

Been doing it for YEARS, as in since the 1980's, and NEVER had any complaints and NEVER felt any ill effects from any of the oil's produced using galvanized pipes. And I was a welder too and so absolutely understand the toxic problems associated with breathing in zinc fumes.

BUT to be clear, first off there is no heat involved in the extraction process (and believe me it takes a LOT of heat in order to burn zinc oxide). Second, butane does NOT react with galvanized steel and so there is zero probability that the any zinc will leach out in the extraction process (especially considering how short a span of time is involved). Third, even if you failed to clean your galvanized parts prior to using them (not the most brilliant move) any minute amount of zinc oxide that might exist on the inner walls will be negligible, and HIGHLY unlikely to cause you ANY harm, especially considering how little anyone would ingest at one sitting (seriously, I don't care how big a stoner you are, ).

So the alarmists running around with their hair on fire with all their dire warnings basically don't understand what they're talking about or don't have a firm grasp on the process that takes place during a butane extraction and/or smoking it afterwards, lol. All the talk about "metal fume fever" is ridiculous! This is an OCCASSIONAL affliction of welders and foundry workers who are chronically exposed to far greater amounts than ANYONE who's smoking BHO. Seriously, people really need to KNOW what the hell they're talking about, not just Google stuff and then run around acting like Chicken Little. Seriously.

Lest you doubt the veracity of my claim about butane reacting with galvanized steel, here's a short list of substances and whether they corrode or otherwise react with it.

P.S. Yeah, yeah, I know it's an old post, but there's so much wrong information out there that people can still stumble across that, for the beginners sake looking for answers, I feel it's necessary to correct the bullshit wherever you find it ;?D

There are, of course, several very real hazards associated with the extraction process that people should REALLY be concerned about.

Like NEVER EVER EVER EVER, EVER, doing an extraction indoors is of course THE number one concern. However if someone is stupid enough to do so, then hopefully any resulting explosion will kill just that idiot and do us all a favor by removing his/her DNA from the gene pool (thus furthering the evolution of the human race, see the Darwin Awards, lol). Seriously, how can anyone be THAT stupid?

NO open flames, sparks or ignition sources ANYWHERE near the process. Ditto for the above statement.

Always use top quality, finely filtered butane. Most of the stuff at the super market and Wally World is shite and contains trace heavy metals and petro residue. Buy the good stuff online or at your local tobacconist. Do a residue test by spraying a moderate quantity on a glass or mirror, let it dry and see what's left. Top shelf butane leaves little to no residue.

If you're using galvanized parts (or any metal for that matter) make sure to clean the parts well. Aside from dust, dirt and other contaminants, there's usually an oily, smelly, coating from the factory you don't want in your wonderful honey-oil. You can use any number of solvent cleaners and degreasers (brake or engine cleaner for instance) and then follow that with iso-alky, acetone or any clean non-polar, just be sure they've completely evapped before starting your extraction process. Easy peasy ;?D

Myself I use glass, plastic or stainless. It's funny what can cause static electricity.

Yes indeed, like dry climates and polyester carpets, lol. But again, if you do it outside, there's little to no danger, especially if there's a nice breeze. If it's perfectly still then a fan blowing lightly across the work area increases your safety (just not directly on the plate, don't want any contams blown into your plate ;?).

Galvanized is a industerial term refering to a rust-proofing process , as in the process it's self

A galvanized product can and usualy does cotain a number of other metals ,and other rust proffing products , Lead is still very common in Galvanized steal ,as in gal. steal gas pipe like found in local hardware stores.

Domestic water lines were once made out of galv. steel , this process was stopped for many reasons (almost everywear in the US) including the leaching of metals and chemicals out of the pipes

I dont think using galv. to run 'BHO' is a good idea . Food grade stainless is not cheap , but you dont need much
