Neat tool for cleaning off rust.

I wondered what he did to clean the core so well, and not put it in a tumbler, or use chemicals or sand . the metal was very nice.

He said he used a "pneumatic Jet chisel", He uses it to take heavy paint off of engine blocks on antique tractors and cars he restores. he said it takes the thick paint and rust off with ease.

I'd heard fo them but never did see one used, or their finished product. he said it beats using a wire wheel, in a drill, and it doesn't jerk and fly around. After seeing his finish product before prime and paint, I was really impressed.

There are different makes and types. He says he got an attachment to put in a typical air chisel, but you can get a dedicated tool as well.

The boat I bought, the trailer is quite rusty, and it's going to get stripped , primed and painted this winter, and I really wasn't wanting to use paint stripper, and the ideal of dancing with a drill wheel isn't my idea of fun, so I'm going to order an air chisel, that is, if I can't find one locally.

I figure that might be a cheap experiment.

I've thought of the idea of sand blasting the trailer, I can push it up to 175 psi. with no problem, but I'd have to do it out of doors, which means I'd need to run quite a bit of hose and use a whole bunch of sand. I agree that glass bead is a lot nicer and does a really neat job, but at about 24 bucks a bag compared to $6 for sand. it's more economical to go the cheap route. I was thinking the chisel would be better because I can use it in the warehouse when it's 20 degrees outside with snow blowing up the pazoo.

You need to get used to them and they will put a unpleasant dent in your body if you slip, but they work well.

You still need to do wire wheel and wire brush work though.

For you Navy deck techs, it's a needle gun.

I have a thousand hours using a needle gun back when I was a junior ET aboard USS Everglades (AD-24) about 1966...."Those Were The Days". I don't believe anything makes more noise on a steel bulkhead than a needle gun on 60 PSI of air....(c;....or makes a sleeping Chief any madder...

Now I remember why I was so hot to sew on more stripes!

As you know, a trailer is made (usually) of a lot of heavy, flat, squared stock with little change in it's surfaces. With exception of brake lines and fender, suspension supports, it ought to do well on the majority of stuff. I haven't looked that much, but if I can un-bolt the fenders. I'll do them individually, as well as the total frame. I might look things over and wait till this spring, because I can dump the tub off into my neighbors pond, and re roller the trailer and do it all at once. But, thanks for the tip on angling the needle gun. I have seen pics of them that do have the needles in an "upward" angle.
