Depending on what media you are useing sand, artificial abbrasives, glass beads all have the ability to produce silica dust. NASTY NASTY stuff. You don't want to be breathing it so use a good quality respirator. Media blasting is a great way to get rid off rust and it will easilly remove rust from spots other methods could never reach. The ral term is medai blasting not sand blasting as there are several different things that can be shot through the gun such as sand, crushed walnut shells, glass beads and artificial abrasives. There are 2 different types of media blasting systems. Syphon feed and pressurized tank. The Syphon feed system draw the media from an unpressurized container useing a venturie effect. As the commpressed air is forced through the gun it passes over a hole (which connects to a hose placed in a container of media) creating a venturie effect which sucks the media up the hose and into the gun where it mixes with the pressurized air and is shot out. The pressurized tank uses a system where the media is under pressure and is forced through the gun. This system will shoot alot more media through the gun than a syphon system will so it can quickly remove alot of rust but it also goes through media quickly. I can empty my tank in about 5 minutes or less. Then you have to de pressurize the tank fill it and start all over again. Most media can be reused as long as you screen it (a tipical window screen works well) to remove anything that is to big to fit through the nozzle of the gun. As the media is used over and over again it becomes finer and finer until its just dust, so new media will allways work the best so it's a tradeoff...$ vs time. You can use ordinary sand you dig up but if its from the side of the road or ocean sand it must be well washed first to ensure all salt has been removed from it. A syphon feed gun A pressurized tank A media blasting cabinet. You will need some way to exhaust all the dust that is created by blasting or you will never be able to see the piece inside the cabinet after a couple of minutes of blasting. This is my main compressor but media blasting uses alot of air so unless you want to blast for 30 seconds and then wait a minute or so for the compressor to build pressure back up you will need a second compressor or more. Second compressor Vitally important is the silver device in this picture which removes moisture from the compressed air supply. To much moisture in the air will cause the media to clog in the gun. You can also see the manifold I have which reduces 2 incoming air supplies to one outgoing air supply. Winter time is a great time to blast as the air has less moisture in it. This is the media that I use in my cabinet. I think it is the same abrasive that they use for emery cloth. Before After RUST KILLS
I think I got the -Cabinet on sale for $200 -Big compressor $400 -Small compresssor $100 on sale -Pressure tank $100 on sale ( i normally don't use it I use the syphon feed gun that came with the cabinet -Moisture trap $50 -50 pounds of crushed glass $10 -25 pounds of black beauty $20 Having said all that I would recommend building your own if you have the ability. Although the cabinet I got was pretty big that differential pictured was about the biggest thing I could fit in the cabinet. On top of that even though I had a vacuum to remove dust you will end up with dust over everything in your garage if you put your sand blasting cabinet in your garage. I took mine appart and built a 2.5' deep X 4' wide X 8' high cabinet on the outside of my garage. out of the original cabinet I used some of the original sheet metal and sand blasting gun $15.99 8 pk 11" x 17" window shields $29.99 (1 of these is stuck to the inside of the glass window or you would sandblast the glass and turn it opaque, then you would have to replace the glass) I replace the plastic every 30-40 hours of use replacement sandblasting gloves $17.99 The biggest cost is going to be your compressor(s) but they have alot of other uses to.
omg sweeeeeet!!! ive got a set of alloys i want to remove the pain on!! would it be difficult to do??
Yes in most cases paint is pretty hard to media blast, especially on a set of rims where the paint is designed to withstand alot of crap that is going to get thrown at it during driving. I would look for an automotive paint stripper. You can media blast paint but its going to take forever, and again some paint will come off relatively easilly and some paints are going to be real stuborn.
right!! dam!!! any idea what id be able to use to strip the paint?? its powder coated silver and i want to powder coat them white... i can get them done for 20 euro a wheel to is also twnty a wheel to powder coat them aswell!! :?
