Aluminium casting

Hi Can anyone help this old codger trying his first casting please. What I am trying to make is an aluminium block, 150mm square by 52mm thick with a 100mm hole in the centre, hopefully with a decent finish as I am short on finishing equipment. I am planning to weld angle iron into a square to make the sides, use a section of 100mm steel tube for the centre hole and tack weld them onto a steel plate to make the mould. I also want to fill the tube to make a disc. Does this this sound feasible please, also will the aluminium, as it shrink as it cools, get stressed by the centre steel tube. When I have poured the aluminimium into the moulds, do I slide a scraper across the top to get a reasonable finish. Many thanks Keith

Painting Aluminium

I'm painting some 1/16" plates of aluminium black. I gave them a wipe down, and used some generic primer and black spray paint. (I originally started off with a paint gun, but it broke). As the plate dries, it starts to crackle in some areas, but not all over. Any ideas what is going on? I've never had this problem painting steel, or wood. Do I need a different type of primer, specifically for aluminium?

Problem with heated aluminium.

I make balls of aluminium rings from chainmail technics and in a test phase i filled those balls with kevlar, which is being used by the jugglers round here. So, aim was to make burning juggling balls from chainmail. I used aluminium cos it conducts heat very well, so that ppl hardly would get burned from juggling with these balls. Problem is, that the aluminium became rough and prim and the rings started to split shortly after the ball was being set on fire. I dunno bout forging, but is there a way that i can keep the aluminium rings away from this effect (tempering?)? Is there a way to light up such balls without damaging the rings?

How to thread an aluminium rod

Hi, I have got some 1 inch aluminium pipes (GI pipes) which I want to thread. I got the threading machine (hand held racheting type) and when I try to thread using that, it goes about 2 threads and after that, its pain - so stiff and even after exerting all my force, the pipe wont thread. I had read that to thread easier, you should coat the pipe with Wax or threading oil. Is there any other tips or tricks that you have used for threading? Any input is greatly appreciated.

Soldering aluminium and stainless steel - input for an Instructable

I am currently working on a new Instructable covering the topic of soldering aluminium and stainless steel. As I am "old school" and don't like to waste money on special equippment unless really necessary, I would like to get some feedback on what to include. So far I covered the basics of the materials, the general how to and what to llok out for. Pics and videos will be made once I am happy with the tutorials to give a better understanding. Aluminium is considered to be hard to solder with no experience and I would like to try to make it possible for the hobbiest to do it, same for stainless steel. For example: Should I include my recepies for stainless steel fluxes or limit it to the procedure of actually doing it without any flux? Is is better to document with nice pictures or videos showing the entire process? (asking the noobs that want to learn it) Is it necessary to go into details like what solder alloy is best for the purpose? For me it is quite hard to go back to a "I know nothing about it state" and make sure everything a noob might need is included. But the longer I work on it the bigger the Instructable is getting with informations that not everyone might need, like how to properly clean the surface, remove the oxide layerand provide the right temperature for the job. Trying to keep it simple but complete and not drifting into boring details is harder than I tough on this topic :( Feedback and requests are welcome!

I need the best technique for cutting a harmonica comb from aluminium or brass(or anything else for that matter!) with a router or hand tools. It needs to be fairly accurate but not necessarily that proffesional looking(I like the homemade look). I have no problem building a guide or template for the router but I want some advice on the best way to go about it. They need to be 100mm x 25mm x 6mm. I can buy sheets at the right thickness so it is just the comb shape I need to get. Thanks

Will laser etching non-anodised aluminium do any harm to machine?

I'm looking for ways to get text and designs on to an aluminium sheet. I've been told that only anodised aluminium can be laser etched, but I wasn't told why exactly. I know laser cutting aluminium can reflect the laser back. I experimented with putting a sheet of paper on the aluminium, then etching just enough so I could use it as a stencil. However, I went too far and got an image on the aluminium. It's exactly what I wanted, but now I'm not sure if I should do any more for fear of damaging the machine. I honestly can't see any danger, because as far as I know, anodised aluminium just has a coating over regular aluminium Other ideas are painting the aluminium and etching that off. I've heard of the type of paint that's close to anodising the metal, but I was thinking a more conventional paint. Should I be worried about damaging the machine  by laser etching raw aluminium? I've been using a 75 Watt Epilog Fusion.

Cutting a square hole? Answered

This is a really basic question—I have managed to get to 66 years old and still be a complete handyman novice, I have tried but my best efforts are lamentable. I think it is because I have never had anyone to show me handy things and have never asked anyone so turning over a new leaf I am determined to start making a few things instead of spending a fortune buying them and paying people to do things for me. My first project is to make a simple slide carrier and I have bodged one up in cardboard but it really needs to be in something stronger so it is rigid, metal would be ideal but very stiff board would also do if I can not cut the metal. I do have a thin sheet of aluminium, (from the casing of an old laptop) that I would like to use buy am frightened of messing up & worse injuting myself! I now realize that I have no idea how to cut a square hole in a piece of metal or, for that matter, what tools I need to cut aluminium in the first place! My overiding consideration is to be safe so I don't want to try, (what to me is a daunting task but probably to you guys the simplest of things) not knowing what I am doing. So can someone please help me out and tell me what tools I need and how to go about cutting a square hole in a piece of metal? Rest assured I will not do it if I do not think I can safely. Thanks.

Metal T-Frame Basics

Hi there, I'm new here and pretty much to DIY in general (except for general repairs) - I'm planning to build a glass dry-wipe board with a simple aluminium T-Frame and need a bit of basic advice. Not knowing the lingo of the trade, its been very hard to find suppliers/information and my research seems to have gone as far as it will ever get, so I figured it was time to ask for some help. I've managed to find a supplier who stocks 25mm square al tubing and was wondering about the best way to construct the frame. My design for the frame is extremely simple - it's just a t-frame with a single crossbar which will run below the pane of glass. I have access to a reasonably well equiped workshop, but unfortunately no welding gear (I hear that al is difficult to weld anyway) which isn't too much of a problem as I would like to be able to deconstruct the frame. I would appreciate any tips which may be useful to a newbie, but mainly I need to know how to fix the al bars at right angles in a non-permanent manner. The desk which I'm sitting at right now has some sort of threaded inserts at the end of each crossbar, allowing it to be bolted a right angles to the frame. I tried googling these inserts, but couldn't find anything which seemed relevant. If anyone could point me in the direction of these inserts or provide an alternative solution, it would be very much appreciated. Thank you

The Ultimate Water-Powered Rocket!

NASA and the Air Force Office of Scientific Research (AFOSR) have launched a water-powered rocket 1300 feet into the atmosphere!The rocket was actually propelled by a frozen mixture of "nanoscale aluminium" (isn't that "dust"?) and water, pumped in at the consistency of toothpaste and then frozen in place. The propellant is known as ALICE (aluminium and ice - convenient, eh?)Earlier this month, the collaborative team, Drs. Steven F. Son and Tim Pourpoint of Purdue, Rich Yetter and Grant Risha of Penn State, Vigor Yang of Georgia Tech, Harold Bell and Frank Bauer of NASA, and Mitat Birkan and Thomas Russell of AFOSR watched as the rocket soared high into the sky, to 1300 feet near Purdue University.ALICE is generating excitement among the researchers because it has the potential to replace some liquid or solid propellants. It is a promising propellant energetically. Theoretically, when it is optimized, it could have a higher performance than a conventional propellant. In addition, because of the abundance and easy handling of the raw materials, ALICE could potentially become the propellant of choice for missions leaving other planets, since it could be (relatively) easy to manufacture from local raw materials and far easier to store than cryogenic fuels.

Possibly the perfect reflective surface for solar?

For those aware of my open source solar energy project, I've just finished giving the first free construction workshop at the Riverside community in Motueka, New Zealand, which went really well. Details to be posted to the blog in the next couple days. But the point of this post is; for the previous two prototypes of the device I used kitchen foil for the reflective surface, stretched over the back of a welded wire mesh. This worked actually quite well, but takes a bit of prep and you can put your finger straight through the thing. But during the course of the workshop I was donated some 60 cm x 90 cm aluminium lithographic offset printing plates, which a guy had picked up for $1.50 a piece from a local newspaper. I rang their printers and was told that they were not only aluminium, but of a particularly high grade. His company alone, and it wasn't large, apparently scraps about 900 of these every week. He said it was a very common printing process, tho I don't know about countries other than NZ. I didn't really need to polish them, despite being over three years old, and they were a nice thickness to curve into a parabolic trough. So: very cheap, very highly reflective, can get everywhere and nice to work with. Should take environmental wear and tear well. Perfect? We just make home concentrated solar a lot more achievable?
