dlwdaw Frequent Poster	posted October 24, 1999 06:49 PM I want to make some KCLO4 and KCLO3 where can I get carbon rods?? thanks ------------------ -dlwdaw "... always look on the positive side of things, blow things up not down" -- Ragnar Benson
Dr-D Frequent Poster	posted October 24, 1999 07:49 PM That question has already been answered. They are at welders shops. Search the forum.
dlwdaw Frequent Poster	posted October 24, 1999 08:05 PM I forgot to mention I'am a lot of miles away from a welders shop. so it would be hard for me to consider being on the road for 2 hours to get a measley carbon rod I spent less for than the gas I used to get up and back. any other sources? a person sen me a URL but I mean like someplace I can drive to, to get them. I dont like ordering by mail. ------------------ -dlwdaw "... always look on the positive side of things, blow things up not down" -- Ragnar Benson
Fjp92 Frequent Poster	posted October 25, 1999 04:54 AM there is corcon rods insite baterys 1.5v can be opend and the rods can be cleand. Sory for shit spelling
VeHeMT Frequent Poster	posted October 25, 1999 12:18 PM Fjp is correct. To clear things up though, the carbon rods can be found inside AAA through to D cells. These are recommended(AAA - D) since they are most commonly available. You would most likely want to use the carbon rods from D cells. In the large 6 volt lantern batteries, I am very sure that there are 4 large carbon rods (although nowhere near the 12" lengths available at the welding shop). The black stuff inside the batteries contains a certain amount of manganese dioxide, which when dissolved in hydrogen peroxide, will form pure oxygen. So it may be wise to save the messy black material.

megalomania Administrator	posted October 25, 1999 04:42 PM Mayhaps a pencil would be a better source eh? Graphite is carbon... ------------------ Visit Megalomania's Explosives and Stuff at http://surf.to/megalomania
Ho ju Moderator	posted October 25, 1999 05:01 PM cool, so it doesnot matter how the carbon atoms are arrainged, as long as they are carbon atoms? ------------------ Knowledge is power, power leads to corruption, corruption is a crime, crime doesn't pay. So if you know to much you will go broke!!
HMTD Factory Frequent Poster	posted October 25, 1999 07:25 PM You'll want to heat the graphite rod before you use them, why? Just torch them and you'll see how much oil(?) is in them ------------------ Disclaimer: I didn't do it, I didn't say it, I didn't mean it, it has nothing to do with me.
dlwdaw Frequent Poster	posted October 25, 1999 08:40 PM could I use mechanical pencil lead. like tape some together? ------------------ -dlwdaw "... always look on the positive side of things, blow things up not down" -- Ragnar Benson
megalomania Administrator	posted October 26, 1999 05:53 PM I tried to use a pencil for the rod, but the damn thing pissed me off because it kept breaking (I was trying to burn off the remaining wood after I whittled most of it down with a knife). In retrospect I should have used mechanical pencil lead, or just exposed the very top and bottom of the lead and left the wood on in the middle (only top and bottom comes in contact with wire/solution). Of course I went to a welding shop instead and bought some real rods, wonderful thing they are. They will break down over time, but they were only $1 each. ------------------ Visit Megalomania's Explosives and Stuff at http://surf.to/megalomania
VeHeMT Frequent Poster	posted October 26, 1999 07:53 PM It may or may not be worth the while, but sometimes the graphite inside cheap pencils(not too cheap, just regualr mediocre ones will do =]) will pop out if you try to push it out with a small rod, smaller then the diameter of the graphite obviously. Other ways could be to crush a pencil in a vise until the wood breaks apart. Try putting the entire pencil in the vise, then try pinching it right below where the graphite is. I like to simply use spent batteries. That way i get the black material which contains some manganese dioxide and the carbon rods. Recycling, just like they told us in school. =]
dlwdaw Frequent Poster	posted October 26, 1999 10:13 PM mega were they called carbon rods, or were they something else? and I have gotton pencil lead like that before just gently sruch the pencil and pull the lead out. ------------------ -dlwdaw "... always look on the positive side of things, blow things up not down" -- Ragnar Benson
Ho ju Moderator	posted October 26, 1999 10:42 PM sp pencel lead would work? you were kinda unclear in your posting mega, i am just making sure. and for the battery that is used can you just use a normal dry cell (the ones used to power big flash lights) ------------------ Knowledge is power, power leads to corruption, corruption is a crime, crime doesn't pay.

megalomania Administrator	posted October 28, 1999 02:49 PM Yes, you can use pencil lead, its just a skinny carbon rod. I am not sure what the welding shop guy called the carbon rod. I asked for a carbon rod and he got me one. I would suspect that the carbon rods in the larger lantern batteries would be the best to work with, alot more there to handle. ------------------ Visit Megalomania's Explosives and Stuff at http://surf.to/megalomania
Ho ju Moderator	posted October 28, 1999 03:37 PM oh i am not talking about obtaining the carbon rods from the the lantern i am talking about the actual power source used. would a dry cell battery work? ------------------ Knowledge is power, power leads to corruption, corruption is a crime, crime doesn't pay.

megalomania Administrator	posted October 29, 1999 04:28 PM Sure, a battery would work, but... You will quickly drain the power and get very little from it. Thats why we use AC powered battery charges, a continual low voltage power source that is just a available as a battery (if a bit more costly in the short term). The good nesw, I recently found an old science book that said, in 1960's zeal, that you can make your own electric rheostat (power regulater). The design is rather simple, if seemingly unsafe (by todays standards, keeping in mind that this book was being marketed to the school aged). You take a regular extension cord, or any electrical cord and YANK it! Keep the plug prong end. Now you have a wire that can be plugged into the wall and has two very dangerous exposed wires at the other end Wrap one of the wires (oh, it help to seperate the wires completly so they can move about) around a lead sinker. The other end can be attached to whatever you have to complete the circuit (in this case a carbon electrode). Place the end of the wire in a GLASS dish (it must be glass and it must be long, like a casserole dish). Use metal and you die, use plastic and it will melt (it is supposed to get hot). Fill this dish with water, and add a little salt (to allow electricity to flow). Now get another length of wire and affix one end to a lead sinker and the other end to whatever to complete the circuit (the other electrode). Here's how it works: The lead sinkers keep the wires anchored to the bottom of the pan. The voltage coming in from the house can be adjusted by bringing the leaded wires closer or farther apart. The closer together they are, the more power there is. Why do you need this rheostat? Because if you just hooked the wires up, you would blow out your fuse box. This very simple device is cheap and I guess effective. NOTE: DO NOT try this quite yet... I am reciting this from memory, I do not have the book in front of me at the moment, but I will get it very soon now. There is a chance I left something out. It even has an illistration I can scan in You can see how a live current project can be considered dangerous by todays standards? And can you see how the trust the "authorities" gave us has diminished over the years? ------------------ Visit Megalomania's Explosives and Stuff at http://surf.to/megalomania
nbk2000 Moderator	posted October 29, 1999 05:54 PM I made a water rheostat many years ago when I tried to make an electric arc furnace from household parts. This might even be from the same book your looking at. Anyways, it worked just fine. Another interesting thing to do with water and electricity is to take a diode and hook it in line with one of the wires so you have a DC current and then attach 2 thick aluminum rods to both wires. You then put the rods in a beaker full of distilled water. Touch the rods together underwater so that you get an arc. As the rods react, they form collidal aluminum powder. This stuff is fine as the finest dust speck. Great for pyro. But it takes forever to get a decent amount. ------------------ "The knowledge that they fear is a weapon to be used against them." www.50megs.com/nbk2000
megalomania Administrator	posted November 02, 1999 01:58 PM That aluminum method is fascinating. Do the rods actually touch, or is there a small gap? I'll bet it is the same book because the rheostat was supposed to be for an arc furnace. Did your book have the glass bottle cutter that used nichrome wire? ------------------ Visit Megalomania's Explosives and Stuff at http://surf.to/megalomania
Dr-D Frequent Poster	posted November 03, 1999 08:31 PM This site has plans for stun-gun also, but also for a varible powersource, something I have always wanted to build. This could be usefull for electolosys if your too cheap to buy a car batery charger. http://www.geocities.com/SiliconValley/Lab/1140/psupply.html
