I notice some new lasers, designed for paint prep, that remove rust and oil and even loose paint. Has anyone here tried one yet? They look amazing in the videos! At around the $200 or $300 price level for the cheaper ones... they seem accessible for small shops. It looks to me like they might be extremely useful on projects with complex surfaces! I think they might also work to remove scale! I’d like to hear advice from anyone who has tried one out.

I was recently perusing my 14th edition copy of Machinery's Handbook (dated 1953) and came across the following quote in the chapter on mounting anvils (when discussing mounting anvils on cast iron or hardwood stands): "An anvil should not be strapped rigidly to its foundation, as this checks the vibration which tends to keep the face free from scales, and renders a high-grade wrought-iron anvil little better than one made of cast iron. When a wooden block is used under the anvil, it is necessary to drive in a few spikes to keep the anvil in place, but these should be so placed that they

I heard about removing rust using molassas, what nonsense. But I had half a bottle in the refrigeraor and decided to give it a try. I put an old hammerhead covered mostly with rust and some remnants of the original red paint into a half and half mixture of molassas and water and sealed it up in a glass jar and put it out on the porch. Nothing happened for a couple of days. I left it soak for the rest of the week. Then I noticed some yellow scum floating on top and checked it again. The rust had turned to a black sludge that you could rub off with your fingers and the pa

Here's a quick question for an expert... I get a good bit of molten slag or scale in my forge. I've been forging meteorite iron and I'm not sure if the liquid in the forge is molten slag or molten scale or something else. I use to think it was excess borax from welding, however in my new forge I get a good amount of this molten material and I haven't used any borax flux. I typically scrape most of this liquid out while forging. I'm surprised how much there is. I keep the forge really hot because of the nickel content of the iron so I forge at welding temperatures pretty much all of the t

Hi All, I know there have been various discussions about scale in the past, I've had a look and they have been helpful. My problem is with the making of ladle bowls and the buildup of scale within the bowl. As the bowl takes shape (I hammer it into a home made former) the scale becomes harder and harder to remove by brush due to the shape of the bowl (can't get my brush in there). In the time take to forge the bowl, the scale builds up and becomes very hard (no doubt due to hammering). I've tried vinegar as apickle but I find it relatively slow and even after a couple days hasn't a

This is a question for a blacksmith/chemist. When I forge mild steel a lot of scale piles up around the anvil. Is this scale chemically similar to magnetite (Fe2 3O4). I meed a couple of ounces of powdered magnetite for some hand made electrical inductors. Powdered magnetite is available commercially but I only need a couple of ounces and I have a lifetime's worth of scale around the anvil. Thanks

Need some help here. I have read in David Boye's book "Step By Step Knifemaking" that you can use brake shoe rivets as pins for knife handles. (p145) A female 7 and a male 5 fit each other. The problem is that I have gone to Oreilly's and Fastenal and neither has or know what the product is. They have what I call pop rivets but its not even remotely the same thing. I still owe the guys in my wedding party the knives I promised them so any and all help will be very appreciated.
