I found a 19-pin air needle scaler for sale online that I think might be just the thing to help me remove all the concrete-like road crud from the frame of my 1951 half ton I'm trying to coax into a street rod. The grease, mud and dirt has hardened into really thick, hard crud that's difficult to remove. Anyone have any experience with one of these and do they really work good?

Thanks

A member here, Lugnutz, says the one he purchased at Harbor Freight worked very well on his crud......may check it out or ask him.

I have used them over the years in some of the jobs I worked at.
It should work good on that crud. It may also leave real little dimples in the metal.
Very loud and it should not used on body metal without a lot of care.

They're good for removing slag from stick welding jobs. They do peen the metal, so if the surface finish is important, it might be a good idea to use a less-aggressive cleaning method like a cup brush on an angle grinder. Eye and ear protection are a must- - - -those flying pieces of crud can cause some painful injuries and the noise is hard to tolerate.

I have used these before on Military equipment with multiple layers of thick paint , grease and crud. They do a great job, just really loud and leave your hands buzzing for hours.

I made a video showing how well a needle scaler works. A wire wheel or grinder can’t get in to corners, but a needle scaler can. VIDEO LINK HERE I mistakenly call it an air nibbler, but I meant needle scaler.

Been using it for years on frames and castings. I spray gas on the area while using it. The trick it to adjust the air pressure down. If you do that you won't get as much peening. Works very well in corners and an initial degrease effort.

Thanks for all the good replies fellas! Sounds like you all agree it’s a good tool. Thanks Lugnutz for the video. Really know what to expect now. I’ll be sure to buy good ear plugs too. LOL

Hey look! It's a ...
Double your hearing protection -- use plugs AND muffs. They are NOT kidding about the eye protection. Use goggles or something that protects from the side, bottom, top -- all around.
