Editing Media blasting

==Media blasting tools== ===Blast cabinets=== ====Where to buy them==== *TP Tools and Equipment sells home and commercial blasting cabinets, abrasives, nozzles, parts, as well as blasting cabinet kits and plans -- http://www.tptools.com/d/12_Abrasive-Blasting.html . *[http://www.nortonsandblasting.com Norton Sandblasting Equipment] *[http://mediablast.com Media Blast] ====How to build them==== *http://www.jalopyjournal.com/forum/showthread.php?t=143854 *http://www.hotrodders.com/forum/sandblasting-cabinet-homemade-79837.html *http://www.ford-trucks.com/article/idx/5/007/article/Build_Your_Own_Grit_Blasting_Cabinet.html *[http://www.autodidactics.com/sand.htm Blasting cabinet made from dishwasher housing] *[http://www.hotrodders.com/forum/building-your-own-sandblast-cabinet-44167.html Building your own sandblast cabinet discussion] *Interior coating can be made from something soft, rather than hard (rubber?). Norton Sandblasting Equipment sells rubber curtains for this purpose. Spray-in bedliner has been suggested. ===Media blasting guns=== [http://www.zendextool.com/speedblaster/ Zendex Speedblaster] ==Where to get media== Locally, online, cheaply? Many welding shops and some hardware stores will either carry or can order, many of the different types of media. Be aware that like most things, it will come cheaper of you buy in bulk! ==Dealing with dust== When the blast media wears out, it will create more dust. Also, can use a [http://www.grizzly.com/products/1-HP-Dust-Collector/G8027 dust collector]. You need air flowing into the cabinet, as well as out. Some creative solutions on dealing with dust are here: http://www.hotrodders.com/forum/blasting-cabinet-clouds-up-136430-2.html . ==Blast cabinet visibility== Try an external light or two shining in the blast window, or inside the blast cabinet. Window can be made of tempered glass, with a replaceable polycarbonate film taped to the inside. ===Shop vacs=== You can burn out a shop vac using it to evacuate a blast cabinet -- the media is so small it gets into the motor, and is abrasive. Also, the paper filter gets clogged very quickly. One suggestion is to wrap the filter with a layer of foam (like some car filters). Shop vacs have low CFM compared to most suitable fans, so they aren't going to work very well -- you need a more powerful fan. ==Different types of media== List of various types of blasting media, and their purposes. *Alumaglass *Black diamond *Star blast *Automotive glass beads *Quikrete fine sand *Walnut shells *Black beauty *Crystal grit *Silica sand (controversial: http://en.wikipedia.org/wiki/Silicosis) ==Sandblasting sheet metal== Cautions about this. * Prolonged sand blasting of thin sheet metal causes frictional heat that may cause the metal to ding, warp, or pit. Be aware of this if you especially are going to be doing a long, flat, unsupported body panel. The best way to avoid this on long spans is to spread out the blast from the gun so that not one area recieves the brunt of the abrasive blast for a long period of time. It also gives it time to cool. ==Recycling media== *Don't recycle media that has been used to blast undercoating -- it contaminates the media. *Most media recycles very nicely, with the larger particles breaking down into smaller, sharper ones. Exentually, it will be broken down so far that it cannot diffuse into smaller particles, and the media will have to be replaced. ==Safety== The BARE MINIMUM when doing open-air blasting is- (for when you first start off) *Long pants and sleeves *Fully enclosed shoes (remembr to put your socks over you pants!) *A facemask with safety goggles worn underneath *Leather Gloves (media dosnt feel the gretest on your hands when coming out at 100PSI+) *Respirator (NOT a cheap paper one, the cartridge-type is the one you want) MUCH BETTER PROTECTION- (when you gain experience/work-load,size) *Full coveralls *Full blasting mask *Long leather gauntlet-type welder' gloves *Leather work boots (must be over ankles) ==Resource dump== These need to be reviewed and incorporated into the article. Once each resource has been incorporated, move it into the References section below. *http://davepropst.com/Article/Art5/Article5.htm, http://davepropst.com/Article/Art5/Article5b.htm, and http://davepropst.com/Article/Art5/Article5c.htm *http://www.fordification.com/my67-p12.htm *http://www.hotrodders.com/forum/sandblasting-cabinet-homemade-79837.html *http://www.hotrodders.com/forum/newbie-but-not-new-118463.html *[[Rust#Media blasting rust]] *http://www.hotrodders.com/forum/what-kind-sand-do-i-need-sandblaster-40114.html *[http://mediablast.com/tech-library.asp Media blast technical library] *[http://en.wikipedia.org/wiki/Abrasive_blasting Abrasive blasting page on Wikipedia] *[http://www.bestofblasting.com/ Best of blasting -- extensive site] *[http://www.ustechnology.com USTechnology.com] ==References== *http://www.hotrodders.com/forum/sand-blasting-cabinet-question-94622.html *http://www.hotrodders.com/forum/best-sandblasting-media-65731.html *http://www.hotrodders.com/forum/sandblast-cabinet-coating-115718.html *http://www.hotrodders.com/forum/blasting-cabinet-clouds-up-136430.html
