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've been smelting for quite a while and now want to make some flash powder, all tutorials use a blender or rock tumbler and aluminum foil, which I do not have(I have aluminum ingots, much more aluminum then just foil.) Can I smelt it out thin and file it finely?Or is there a better way

OK so I know you can get aluminum from an etch a sceh, or you can grind up a chunk of aluminum. i dont have an etch a sceh or a chunck of aluminum handy so, I was wondering if I could use chaff from a B-52 it is very fine aluminum. is almost looks like shiney hair but its aluminum... could I use that effectively or is it too thin, its like aluminum hair?

I need to weld 3/16" sheet aluminum for a boat i'm making and want to do it at the cheapest cost. this welder (http://www.harborfreight.com/90-amp-flux-wire-welder-68887.html) says it won't do aluminum (and i'm not sure 90 amps would be enough anyway). Is that true? What if i bought the 180 amp model? Any suggestions for other welders?

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've read that aluminum doesn't rust, and that it can be corroded but that it doesn't really make it look worn out/old but makes white blotches. I need a solution to make it look worn out, doesn't need to be a fast process though.

Question by the poodleo | last reply
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. ??????

Question by cadams15 | last reply
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).

After determining that a hard drive platter is aluminum (I don't want to try to cut the glass ones), how could I cut it neatly? I'd like to cut out neat rectangles for a small kaleidoscope. I tried a hacksaw, but it was a messy cut, and I expect it bent the optical surface a bit. I tried a rotary tool with cut-off discs, but the aluminum chewed up the discs really fast--I could see the discs shrinking before my eyes into tiny circles.

I've been really interested in at home aluminum casting and wanted to make a forge and try my hand at it. Before I started I've done a lot of research and video watching. It seems it is most popular to use the lost foam method. I was just wondering if it would be possible, and what materials to use to make a simple reusable mold. If I was to cast 10-12 of the same object it just seems easier to make a mold then forming and shaping 12 pieces of foam. Since I'm just getting started i wouldn't be casting anything too complicated or big. Thanks in advance!

Hi all, I have a DIY boombox project made from a train case where I need a badge made to cover up a "mistake". I can provide an Adobe Illustrator, EPS, DWG, or DXF for the logo and shape of the badge. The finished piece will be 3.25" wide by 1.5" tall. As much as I'd like to do this on my own, I'm not keen on working with acid and don't have the time or work to build my own CNC or laser cutter. I will be happy to pay for time and materials as long as it's reasonable. Also, I'm in Northeast Ohio, if that matters to anyone. Thanks!

I've been casting small aluminum statues using the "lost Foam " technique. My success rate has been about 60%t070%because of the aluminum freezing in the long narrow parts of the mold.

How can I correctly identify aluminum? Aside from the weight, how do I find out if it is pure or some alloy that will make make even the vultures drop dead when smelted. 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! The letters have to be out of aluminum for rust reasons. 2nd Question Does zinc alloy aluminum rust in the same fashion? 3rd Question Brass. I haven't researched it yet, but could anyone give me a clue as to smelting the stuff? Thanks
