Topic tags/keywords: rust removal There’s a lot of new emerging technologies for removing rust and conditioning metal surfaces. I’ve always believed that sandblasting was the be-all to end all. Then there was rust dissolving fluids, abrasive pads and good old elbow grease with a wire wheel. And then, I saw some videos about processes that I’d never heard of before. Outrageous!! Imagine dry ice shot from a nozzle to immediately remove all traces of rust!! Or, removing rust by laser! Check out these two suggested videos: https://www.youtube.com/watch?v=cFSsiB-PrYw https://www.youtube.com/watch?v=0TcHNsPr9Nw And to think of all the planes, saws, chisels and wrenches that I cast aside over a lifetime due to corrosion and rust. -- Einstein: "The intuitive mind is a sacred gift, and the rational mind is a faithful servant.

Thats pretty cool, thanks for sharing. If those “maker place” type of shared shops get something like this then thats another reason for me to go. |

The dry ice stuff has been around for a while, and it’s great for cleaning but not so much for rust removal. If you notice in the video, they say as much, referring to ‘hand work’ with sanding pads, steel wool and other abrasives when it comes to surface rust. To me, it seems like only a slight step up from a pressure washer with slightly less mess (and more costly equipment + media). The laser stuff is the real deal though – unfortunately it’s on the expensive side, particularly for home use by weekend warriors who would only rarely use it. I can see a few advantages to it, such as being able to de-rust parts in place, and less cleanup than traditional sandblasting. You also don’t have to worry about such things as Siliconosis ;) Good news is the prices have been coming down as laser technology becomes more and more available to the masses. For me, electrolysis is the go to rust removal method for larger items. Smaller stuff will get evaporust. I pretty much gave up sandblasting a while back just because it was too much hassle, and more modern blasting media just didn’t work as well as good old sand – which can be dangerous to use without adequate protection. Most other methods, such as chemical strips, wire wheels, sanding flaps, etc… work great on open surfaces, but are useless on highly contoured pieces with lots of little recesses and hidden areas (including hollow forms). Interesting topic though… look forward to others insight into the never ending process. Cheers, -- Brad in FL - In Dog I trust... everything else is questionable |

Old news for me? Dry ice media blasting is a favorite in the mold removal industry. The frozen temperatures keep mold/dirt in solid form during removal. The mold removal folks have special and spray and HEPA vacuum heads. It works on wood, without removing wood. Laser ablation has been around since 70’s. Have used it on production line to clean aluminum oxidation before welding. Designed and built green laser semiconductor marking machines as well. The up front cost is very high. A small area unit can cost $100K, and larger machine upwards of half million. Ultra precision laser control machines can cost over $1M each. Sorry if this deflates your glee. It is still cool technology! Enjoy your media blasting adventure. -- If it wasn't for bad luck, I wouldn't have no luck at all, Doom, despair, agony on me… - Albert King - Born Under a Bad Sign released 1967 |

Hey, I just remembered another recent technology that might be applicable to the rusty tool restorer. I’ve seen cars blasted with sodium bicarbonate, like as if using sandblasting equipment. Probably environmentally friendly, it’s just baking soda after all. In all cases, there is risk of lead exposure if it’s present in the paint being stripped. -- Einstein: "The intuitive mind is a sacred gift, and the rational mind is a faithful servant.

Last night I watched a video where the guy used wood glue to remove rust off a plane iron. I might try it the next time on a plane sole to get the hard to reach areas by the frog seat. |
