Building a Foundry?

So I've been experimenting with building a mini foundry made out of steel cans. I've experimented with several different fuels, fuel injection systems, oxygen injection systems, crucibles, and different metals. However, the only metal I've ever been able to melt with it is zinc. (if you don't know, zinc doesn't take alot to melt; only about 700F) My target metals are aluminum and copper, but despite over a year of experimenting, I've never been able to melt either. I would like to know what I'm doing wrong, or what I could do better. Here's the rundown of the furnace's construction: The fuel I'm currently using is propane. The foundry isn't big, (you could fit it in a backpack) so I just use propane canisters for torches with a normal output line on the end. The line runs to a small piece of glass laboratory tubing with a tiny nozzle on the end which is about 1 mm in diameter. The propane shoots out as a stream and mixes with air utilizing the venturi effect. The propane mix then shoots into a large metal pipe about 2 cm in diameter. It then bends up at a 90 degree angle and enters the furnace, which is in essence, a steel can with a hole in the bottom. inside this is a steel can cut in half with a thick wire through it to suspend it above the burner.  So what could be improved? When I run it at full blast, the whole furnace glows orange, but no metal melting happens...

Campfire powered foundry?

Hey guys, Ive been checking out a few of the foundry instructables here, and I want to make one. I have 2 problems. 1, I don't have any charcoal, and two, I don't have a fan. So I was wondering... is there a way that I could make a foundry that would get the heat from a campfire or firepot? I'd there are 101 uses I can think of for molten aluminum.., Thanks in advance!

My PROPANE (!) Foundry

Hey, I'm sure you've read some of my other foundry questions and comments, so here's another. I have been using this with charcoal briquettes for quite some time now, and finally built a burner to convert to propane. I made my first melt with it earlier, and I don't think I'll ever switch back, no matter how high propane gets (price). I built a burner according to the instructions here, and it turned out fine, except that the flame won't leave the burner tube completely. It fits pretty well in my helium tank foundry/furnace (a .gif on how I made it is below), heating it up to melting temps on full blast in probably <10 minutes. It is SO much cleaner, easier to make multiple melts( no refilling charcoal), and is alot quicker in starting and finishing a melt (no setting up blowers, positioning charcoal, and that stuff).It was (at first) an easy choice to go with charcoal (cheap, could even be made for free), but after a couple melts, the fun got replaced by work, and I stopped melting metal. I discovered propane, built my burner for $35 total(including regulator) and was up and running within a day. ~$20 for a refill on propane when I run out is COMPLETELY worth it. Sorry if this seems kinda persuasive, but I am trying to help either people on this site, or one of the countless wanderers from Google.Some pictures of my testing (not my burning setup) setup are below.

Is this a good foundry burner design?

Is this a good design for a a foundry burner? The hose hose for the natural gas are connected with jb weld. The thing on the back is a way to connect my output of my shopvac to the burner. The pipe attached to the other pipe is for the oil hose to be connected to. The front is tapered inward for a venturi effect. Its welded to the other pipe and I think I might put some jb weld over it to air proof it. I need to grind down the front of the oil pipe to make it flat with the outside pipe.

Helium Tank Aluminum Foundry

I was looking through the internet, and was linked to this page. There they used a freon can for the foundry shell, but I thought those small helium tanks would work too. I kinda knew that a dremel wouldn't cut through it, but it is just what I put on there. I used Inkscape and GIMP to make it.Also, does anyone know a good source for fire clay? I've heard that masonry supply stores are a good bet. Another thing - does anyone know a good page on a cheap, simple, charcoal foundry? I made a .gif animation describing my ideas, below. In the animation, I meant to put the part about cutting the hole for the blower in the beginning, too (after I cut the top off).

Have there been any major incidents in your area, and if so, have you witnessed any of them? It could be good, such as a movie filmed on your location, or bad.Three come to mind for me. First:There was an explosion at the Altlas Foundry in Tacoma, it knocked out power as far as Gig Harbor. I remember the lights going out and hearing about the explosion, but until recently, I never knew just how large the explosion was. I am amazed at how massive it was, I heard it was one of the largest BLEVE in history. Second:Galloping Gertie of course! That goes without saying.

Molding Aluminum: With Gravity Die Casting

It's expensive, untested and dangerous.The idea goes like this. Start with a coffee can foundry, possibly powered with Biodiesel or Propane. Then design a mold for what you want to build using Autocad or some variant thereof. After it's finished, send the design to a machine shop to have it built out of steel. When you receive the permanent mold, melt the aluminum and pour into the mold repeatedly and often.The idea seems like a good one to me, I'll be testing it soon enough using common screw clamps to keep the mold tightly secure.Has anyone here done this? The closest I've come to doing it myself is pouring into a muffin tin.The photo below is a picture of the results which was taken from another board found here, you'll need a login, the photos are located in the forum under Machining and Tooling.Give me a shout if you dig the idea.UPDATE 5/24/07It works! Using my Harbor Freight Mini-Mill I cut out pockets in two pieces of 1018 steel, each about an inch deep, and four inches across. I then cut inlets in both pieces and welded some scrap steel U channel on the tops of both mold sections to form a pool enclosure for the excess aluminum to collect inside of and stay safely contained.Then I lit the candle on my foundry and melted the aluminum while at the same time pre-heating the molds, (connected using C-clamps) in the oven. When the aluminum melted, I poured it and it instantly solidified. After about 2 minutes of running around in a panic I cracked the mold open. The detail level is incredible. Impressions made in the mold with a fly-cutter can be seen in the casting. The casting is bright, shiny, and seemingly devoid of any burs usually associated with unfinished aluminum castings.I'll provide photos later of the test mold and casting.

How can I make a giant bike cog like this one? Answered

Here's a site with  the inspiring article: http://www.cnet.com/news/fast-fixie-bicycle-with-giant-chainring-aims-for-100-mph/  Anyways, I want one. First of all I would suppose I'd need a pattern. What program would you suggest I used to make a pattern?  A solid circle of metal with teeth on it will do. I'm thinking of gluing a pattern to a piece of metal, cutting it out as best I can with a grinder then going bike to clean it up with a tungsten carbdide dremel bit. I gues it could be a few thinner sheets of metal that could be  spot welded together. I dont have any tech shops/idea foundries in my town. I say that because I'm wondering could I just create some type of file that a mill machine could read and cut it out for me? I have a couple different reasons for wanting a larger cog, the practical one being I want a cog large enough that the pedals would be moving around very slowly so you could just shift your weiht back and forth, more falling with your body weight than pedaling. The 2nd reason, more lofty and long term goalish is if you can get this much power from a bike, to propel it 100 mph, it just seems reasonable that a human powered aircraft is within reach, as in attatch a hang glider to a bike and have the pedaling able power a propeller once airborne. Anyways, how would you go about making a giant cog?

New kayak design, is it good?

Hello everybody! I've moved most of my robotics projects to Let's Make Robots (All LMR are belong to us!) and I'm gonna do some wood-working now! I decided to build a kayak. Why? I dunno, I want to build one, and I always wanted to go kayaking. No I'm not gonna go take lessons (tips/tricks are welcome), I'll train myself. I'm expecting a couple capsizes. LOL. Anyways, I found a program that helps to design kayaks called Kayak Foundry. The software tells me where to put the sheer strip, where the waterline will be, and it also generates the forms to build from. The only problem I have is that this thing will cost $400-$450 to build. Before I invest that kind of money in a possible failure, I need to know if I have a stable design. Below are the cross sections and a model I made in Google Sketchup (gotta love free software!). Take a look at them, I need to know: -Is the design stable -Will it float with a 185lb man in it The software gave me a stability rating of 90 (out of 100, with 40-50 being a racing kayak) Also, there are pictures of data from the software. the red line on the graph is my design, the black line is the target. Also, on the volume distribution curve, the line should be right in the middle (the cockpit or whatever it is called should be in the middle of the boat.) I guess I forgot to save or something. If you can help, please do. I'd rather not spend $400-$450 dollars on an unstable boat that always capsizes. Thanks, Gimmelotsarobots

Solar deathray smelting? Answered

So Im not sure of the capabilities of the fresnal lens in terms of maximum temperature but I've seen them melt brass. I was thinking with a solar death ray on top and a charcoal fire on bottom that I could get temperatures to melt steel. I have drawn a rough sketch of the overall Idea I really need someone to further refine this idea into a working schematic that I can create when I do I'll document it all and relay the results on here to help others recreate it. Now This setup will be behind my greenhouse on the corner of my property on the side that would be hidden from the sun, however if the base pivots on an axel I'm thinking of using, then it will be able to catch the sun from all the points when it's most useful. In that I'll also have the fresnal lens on a pivot bar to help get it on my focusing lens which will be a plastic and water style parabolic lens my only concern is that if I can't turn that lens will it hinder my project entirely or will it be fine, plus I'm not sure about focal point on this kind of lens. On the sides of the frame I'll build for the fresnal lens I'll have strings attached for turning on the bar and I'll be able to lock it in place to keep from fires around my smelter.. Hopefully! Overall dimensions may appear small in the drawing but the fresnal lens should be at about I'm guessing at roughly 25 feet off the ground, or roughly 7.5 meters and the focal point in the middle will be found and adjusted to the fresnal in terms of height. I think it was roughly 1 meter so I'm not sure entirely I would love some feed back on this idea as I plan to make a smelter with it to complete my in progress foundry I'm building in my shed.

Radioactive lift controls recalled in France

NEW DELHI (AFP) - India's atomic safety body said Thursday that radioactive scrap metal which found its way into buttons installed into lifts in France had been traced back to a western Indian foundry.At least four Indian firms were involved in the manufacture of the components, an official said, but it was still unclear where the contaminated scrap originated."We are tracking back the whole chain," Satya Pal Agarwal, head of the radiological safety division of India's Atomic Energy Regulatory Board, told AFP."We are taking steps in each place. Exporters have been advised to buy monitors to check their materials before exporting."France's Mafelec firm delivered thousands of lift buttons to Otis, a subsidiary of the US elevator company, which installed them in at least 500 lifts in the country over the summer.Otis has said it is now in the process of removing the buttons, after France's Nuclear Safety Authority announced Tuesday that 20 workers who handled the lift buttons had been exposed to excessive levels of radiation.The French nuclear safety agency has said the lift buttons contained traces of radioactive Cobalt 60.AFP articleSteel items imported {into Sweden} from India showing faint traces of radioactivity were found in Sweden, before the same substance was traced on Indian-made lift buttons in France, officials said Wednesday.The levels of Cobalt 60, a radioactive form of the metal, were considered harmless and the steel components have not been recalled, the Swedish Radiation Safety Authority (SSM) told AFP."Dutch customs discovered that a shipment of industrial flanges from India to Sweden showed traces of Cobalt 60," SSM spokesman Mattias Skoeld said.Focus Agency feedFrench elevator maker Otis said it would remove the buttons from hundreds of lifts it has installed after a radioactivity scare over Indian-supplied materials.The company made the announcement after France's Nuclear Safety Authority (ASN) said 20 French workers who had handled buttons used in lifts had been exposed to to excessive levels of radiation.An Otis spokesman said the firm's plan to remove the buttons "concerned 500 to 600 lifts out of the 2,500 that Otis has installed, modernised or repaired between August 21 and October 9 even if there is no danger for users."The ASN classed the incident at factory of the Mafelec firm in the east-central French town of Chimilin at "Level Two" on a scale of seven because of the exposure of more than 10 people to doses exceeding the reglementary limit.SA Times article
