I'm building an aluminum bridge for my railroad. I need to solder the side braces rather than using screws and nuts. I've ordered a 150 watt chisel soldering iron and need to know what items (solder etc) I need to perform this project. Any assistance greatly appreciated. I would rather not use a torch on this project unless absolutely necessary.

I have some aluminum hydroxide and I have been trying to find a way to strip the Al(OH)3 of it's hydroxide ions to form an aluminum precipitate. It's nonsoluble so a reaction in an aqueous solution does not seem to be an option, also considering that the only other more reactive metals than it would ignite upon contact with water anyhow. Does anyone have any ideas how to accomplish this?

I was reading all of the labels on things in my house, mostly spray-able things like spray paint, spray adhesive, spray enamel, etc., etc., to see what's flammable, and on the bottle of ammonia we have it says "Do NOT use to soak aluminum utensils in...." or something like that. What does ammonia + aluminum equal or do? Is it flammable? Thanks all you chemistry-buffs!

I'm looking for a website that sells cheap aluminum/plastic cases and i just need a generic kind, no branding needed. i know they cannot be that expensive if you can buy a $15 pokerchip set that comes with one. or a kid's board game that comes in one for $10. i've done alot of searching and all i come up with are the expensive designer ones that start at $200. i will be cutting holes in this case making modifactions to make a mobile workstation for my laptop so i dont want to spend $200 on a case that i'm going to cut up. it doesnt have to be aluminum and doesnt need a lock, but something like a briefcase (with a handle) is ideal. here are some images, anyone have any ideas? btw: the case i'm looking for has to be at least – 6" thick, 18"wide and 14.5"tall, must be a hard case (made of anything), must have a handle and open like a brief case.

I have some parts that i need to cut from aluminum. Unfortunately I don't have access to any CNC machine, so I'm thinking of cutting them myself by hand... Is there an easy way that I can get my drawings on the aluminum? Perhaps printing on photo paper (using my ink printer) and an iron? Plan B is to use some sort of glue and glue the drawings on the sheet... Any suggestions are welcome!

For my woodshop class I am making a cane/"pimpstick" and I am making a custom head for it. I want to cast it in aluminum using the lost wax technique. would normal plaster of paris be a good material to use for the mold? the peice is about 3 cubic inches. I was thinking about having two "fires" one to heat my aluminum and another to heat the mold so it doesnt shatter. Is that workable? P.S. It would be a one use thing so no need for anything expensive. I have literally 10 dollars to spend on this. Thankyou, bud

I was thinking about 3d printing aluminum and was wondering if you could do something like this. You have a stainless steel air tight cylinder, surrounded with some refreactory, then nichrome wire, then insulating refreactory. The first layer of refractory is to prevent an electric short between the wire and the stainless steel cylinder. Stainless steel so it will take longer to oxidize. You would fill the cylinder with aluminum, close it, turn on the heater, t would heat up the stainelss steel and aluminum and melt the aluminum. Temperature could be regulated. Air would go to a hole in the top of it, the air would be regulated by a solenoid valve and a a pressure release valve. A needle with come out of the bottom, however it would be bent into a upside down U shape and one side would poke out the bottom, this would preven the aluminum from running out when there wasn't pressure. When the solenoid is open, aluminum comes out, when the solenoid is closed the release valve is opened to get rid of any excess pressure and stop the aluminum flow. This would be put in the place of the the traditional extruder, would this work?

Ok, i need aluminum bronzing powder, no not for thermite, there are more fun things to do with it, but along the same lines. The only problem is at all my local crafts stores, hardware stores and paint stores, no one sells it. I thought about using an etch-e-sketch but big ones are hard to find, kinda expensive if i wanna buy 5+ and also, half the powder is not fine at all. Grinding up aluminum foil isn't gonna work for me becasue i can't find a ball mill under $100 (not even a crap one), and i sure as sh-- ain't gonna sit there filing it off a bar. Parents aren't going to let me buy it off the internet (i wouldn't any way the prices are outrageous and they limit how much u can buy a year), electrolysis maybe? But what would i use? A battery charger? Or are their secret code names that they sell it under at hardware/paint stores? HELP

I need to join aluminum sheets together. When I say sheet, all I mean is the body of a coke can. So, I would cut the top and bottom of the can off, then make a vertical cut to make the body into one long strip. I would do this again, and then I want to join these two strips together, end to end. Would 1/8" rivets work? I thought of solder, but I heard solder doesn't stick well to aluminum. I would prefer the aluminum to stay down. Does anyone have any ideas? Thanks!

Is there any reliant and consist way to create high RPM gears using 3D prints? What I had planned to do is 3D print some gears out, make silicon molds out of them and then pouring wax in the silicon molds. I then would put the wax into sand and then pour molten aluminum into it. To me, it sounds good in theory but I thought somebody else might have tried making PLA 3D prints into metal.

OK. I go to several different scrap yards. I have noticed at this particular one, that they do not crush their cans. I didn't give it much thought till today. As you can see in the photo, they store their cans, in bags, in the back. The people that came to get the cans are putting them into bigger bags and packing them into a huge box truck very tightly as if they are going to fill with as many as they can. Not like it is just going across town. If these cans are to go to another state for a higher redemption price, don't machines read the bar codes to prevent that? Also, the truck had a license plate from Sonora, Mexico. Although that is pretty common around here, that may be part of the reason. ??????

Here's a question for you laser cnc builders out there, how much laser wattage would you need to cut really thin aluminum? Like, only slightly thicker than grocery store aluminum foil. Very thin. This cnc machine would be used to cut custom theatrical gobos (GOes Before Optics) at home. Normally, when we need a new gobo design, we build one in Adobe Illustrator and send off the design to Rosco or some other professional cutting company. But this can get pricy, and can take up to a week, so if one gets messed up during tech week (they do sometimes) we have to cut a new one out by hand. The results are not spectacular. The gobo doesn't have to be mechanically strong, and they don't warp inside of a 525w fixture due to the cool beam. You could in fact use foil, but that's a little too thin to be useful. Any guidance would be appreciated.

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).

Owing to a project I'm working on where I wish to cast letters in aluminum for a wind harp, I have been on a search here on the farm. Have found literally 200kg of scrap brass and and about 35g of aluminum!

I haven't researched it yet, but could anyone give me a clue as to smelting the stuff? Thanks

In the Golden Book of Chemistry, page 64, there're instructions for dissolving aluminum. The book states that HYDROGEN is released when aluminum strips are dissolved in hydrochloric acid and ALUMINUM CHLORIDE is formed. That's about all we get from the book concerning that particular experiment. Just wondering if this is correct, how to test it, what it should look like and what may we [the kids and myself] may do with it if it's actually aluminum chloride. It's a good book, but quite a bit of theory's lacking. Thanks all.

Question by timothy demaegdt | last reply
Hi I was playing with some ideas and wonder if it is possible to get power from a moving piece of aluminum. I know, if you tab the alu, you can get the power because to the eddy-currents geenrated if you have a permanent-magnet near... But what if i wanted to get the power NOT from the aluminum, but from the "other" side like the magnet? If i hold a magnet near a moving piece of aluminum, can i get power from the magnet as well or are the eddys only generated in the alu and not in the magnet since it already has its magnetic field? So the basic question is: How to get power with the help of a moving piece of aluminum, but the tab-point in NOT the aluminum but something geometrically separated. Thanks a lot! :)

Question by Spaceman Spiff | last reply
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.

Recently I have learned the basics of anodizing aluminum, and from what I understand the basic process is to clean of the aluminum bit to be anodized, stick it in a bath of a dilute solution of sulfuric acid, and do some electrolysis with the anodizing bit connected to the anode or positive of a supply, then pulling it out some time later and cleaning it off with soapy water and rinsing, and coloring the metal in a thin runny die, then wiping off excess and boiling the part. So first of all, do I need sulfuric acid? Any substitutes? Will HCL work, or a weak acid like vinegar or even salty water? If the purpose of the sulfuric acid is to allow free ions to flow in the water, I do not see why it would not work. However, I am not a chemist, and my experimentation with electrolysis is limited to 6th grade science and dropping 9V batteries in salty water. (My favorite experiment was at home when using copper and coins as the electrodes and watching blue-green corrosion develop and sink until the copper wire was made brittle and thin. Caused some AA rechargeable batteries to explode in the process though lol!) Also, will any die work? For really small parts, will it be possible to evenly die them with sharpie, standard paper markers, and/or highlighters? What dies will work well? Should the dies be water based, or based on some other thinner?
