Sandblaster

When I saw the sandblaster here, I wanted to make one because well, it's cool. The only problem is that I can't find the gun. From what I can tell, It has 2 intakes and one exit nozzle. I did read the instructable, but it didn't say (as far as I could tell). Can someone help?

need help newbi

Ok guy's i need a little help, or to be pointed in the right direction, backround: i want to buildd a retrofit kit for a existing automatic sandblast curtain.. reason: basically every monument company in the country own's an older automatic blast curtain, that is controlled by limit switches only, and the new ones are cnc and cost 50,000 ish, and the existing machines are screeming for a retrofit kit... i own the "hirons model j" automatic curtain, it an x,y easy as pie thing, my problem is that i can get the parts machined and the rig built, however the g-code is my problem, and i think it will be very easy for someone whom can do it, to do it.. all i need is the machine to make strait passes left to right and back while slowly progressing top to bottom and back, the nozzle will also have a "spindle" motor, that will make it make a circular pattern constantly for the duration of the job, could anyone help with the g-code, ????    i can do all testing as i own the machine,

Sandblasting old wrought iron porch railing, how to,can I do it? Answered

I have old wrought iron porch railing with at least three layers of paint that need to be removed in order to repaint. I have tried paint stripper and it is too detailed a job for this, and not efficient. The railing has two posts that it is attached to with a floral and leaf decorative piece that is attached to each of the posts. These pieces have intricate detail and fine crevices that the paint that is there now has covered in. It is very nice decorative pieces and I would like to preserve them. Please let me know if anyone has any suggestions. Thanks

Question about airbrush

I have an airbrush, which works very well. I was wondering if I put some very fine sand in the pot, would this work as a sandblaster, for etching designs into glass? Thanks, Tom

What can I use to strip powder coating without sandblasting? Answered

I have some tins that I want to strip but they have powder coating. I've tried heavy duty strippers and a sander and a 9" wire wheel sander none of which work that well. Any suggestions? The 9" wire wheel did remove some of the paint but it also burnt or melted the metal faster then it removed the paint. Those cookie tins are thin.

How can I make a dry ice blasting machine?

I have seen commercial machines that use compressed air to shoot a stream of dry ice (CO2) pellets or shavings at a dirty, oily machine to clean its surfaces. Unlike sandblasting, the CO2 sublimates (goes from solid to gas without passing through 'liquid') and leaves no residue other than the crud it blasted off. It can even be used on machines or electrical panels that are powered up! But these machines cost multiple $1000s. Anyone have a plan or experience with a DIY version? Thanks.

Engraving...suppose you had to engrave a corporate logo/name into something like a laptop exterior. ? Answered

It has to be portable and reasonably compact, since clients don't want said items leaving the building. Chemical etches are probably no-go. A cut-out mask and sandblasting works but isn't very portable and you've got the noise of the compressor. Ideally what I'd like is something sort of like CNC where an image can be loaded, and the machine then takes over the engraving process. Let's say .25 mm deep. I have some thoughts but wanted to put it out into the hive mind. I'm a 'keep it simple' guy, so if there's an easy way to do this, I'd like to hear about it.?

Polishing large stones

I am looking for some advice on polishing large stones. I am from New Jersey, and there is a plentiful supply of bog iron. I can't dig a hole in the ground in my yard deeper than 8 inches without coming across some of it. Some stones are small but most wiegh about 20 to 30 lbs. I have several that are at least 150 lbs. I have tried to use them in as many ways as I can think of to decorate my yard. But bog iron is not always an attractive stone. I have seen some small polished samples on the internet and I like the way they turned out. I would like to try and polish some of my larger stones. I could do it by hand but it might take months or even years. I'm not sure what a sandblaster would do to it, but I don't own one and am not looking to buy one. Does anyone have any ideas or suggestions for a faster way to polish a large stone. Thanks in advance.

Soldering/brazing/welding steel, bicycle chains?

Hi, i am working on a project (in Vienna, Austria), and a part of that process will be that i would have to clean a bunch of used bicycle chains and create other, rather smaller objects out of them. they dont have to hold a lot of weight, they vary from 4 to 6 chainlinks or so. At the end I think I will have between 50 and 100 maybe 200 pieces, so it's not an industrial amount but not a single few pieces either. FYI: bicycle chains are made from steel, they are not stainless steel, usually its chromed, there is nickel in it, so when its used they surfaces are often damaged, so it has rust on the surface as well. it has really small hidden parts where grease, dirt and rust stays hidden and stuck too. For the cleaning: I have been cleaning chains to create prototypes and individualised pieces so far with Terpentine and experimented with other types of Degreasers, Soaps, with toothbrush method:) and rags, also other kinds of paint thinners (terpentine doesnt smell so bad, but still removed a fair amount of grease dirt and rust) Degreasers are not very effective, soap and toothbrush and rags take a lot of time. Soaking in terpentine helps but its still time consuming. I havent tried aceton yet. Vinegar and stuff like this dont seem to be so effective either... For assembling/connecting: I have used for individual pieces chain tools (putting a small pressure on the chain link pins, so they are not flexible anymore (as chains supposed to be normally) and then forced bending them in the position they should be in. This is stable enough for the stuff I want to do (they are only decorational) but it's a lot of work, takes a really long time. I did welding too (MIG), but the plates are individual pieces, it doesnt weld so nicely, or its not so easy, and I dont have my own welding machine in my workshop space, I have one in a different place i can use, but i dont want to invest and buy one just for this, and it would be nice if I could do the whole project in my own space, and i wouldnt have to transport so much stuff all the time back and forth... and it's not necessary to have it that strong as i can actually get it with welding, because it doesnt have to be that resistant, doesnt have to hold so much weight, as they are going to be only smaller decorational objects anyway. Ideas and tips that came up, havent been tried yet though, or didnt really work yet: - soldering: with gas flame (torch) and simple solder. i tried shortly, didnt really work though, didnt connect, maybe i give it a try again, not sure what i did wrong though, maybe its just not the right method? - using screw glue (not sure if thats the right name in english:) rather smaller amounts or transparent ones, applying it at the inside points, so it still looks nice. - i havent tried epoxy and i am not a huge fan of the idea, but i dont know enough about the costs, process and the environmental effects of it... - it is an option also to use some temporarily working, not very great but cheap and fast method for assembly as preparation and then just quickly fill holes by welding, i thought about trying soldering or screw glue before welding and just zack, zack zack weld them one bye one, it would be easier if they are somehow already fixed in the position they should be in (as they are small and very flexible pieces of metal otherwise), problem is though that whatever i use as preparation, will be quickly burned by welding, which is in terms of environmental effects not so great, but also has aestetical consequences i guess. - i just read about brazing, i am not sure yet what i would need for it, for smaller stuff, what is the difference between brazing and soldering exactly and how well it would work, what are the costs of investment etc. - for cleaning: one idea i havent tried, just read about it is sandblasting. I would probably have to ask some company to do that, as i really cant afford to invest much more money in equipment right now, not sure if i even have the right space for that, and it seems anyway for 50 or 100 pieces disproportionate somehow. I would like to use a method that is not too bad in terms on enviromental-friendlyness or how to say, not very damaging or too bad chemically etc. it would be important that whatever i do, the endresult: - holds more or less - looks nice, either invisible the parts or things, materials i add so it holds, or it has the same colour/material like some kind of metal. it can be that i will paint it over with some metal silver colour at the end if necessary, for having a consistent colour surface, or to prevent from rusting afterwards. - should be cheap during the process, so low running costs and more or less environmental friendly, and preferably some method to use tools that are cheap or i have access to, not very expensive to invest. - i prefer to do things by myself and not outsource the process to companies unless it has big advantages (like for example if it turns out sandblasting is cheap and really environmental friendly i would consider it actually:))) i am really happy for any tips on these things, before i spend more money on stuff just to try it out and find out it's stupid, or not what i need, not what i am looking for:)
