Rusted Solid 15" Diamond Adjustable

[Makattak81]

I found this the other day, and would like to get it operational again. The adjuster is froze. I've soaked it with Open & Shut. I can move the selector with a chisel and mallet. The screw holding the selector in place won't move. Any suggestions would be appreciated. Thanks.

Drop it in a jar of pure vinegar for a week.

Or you could just sell it to me.

Electrolysis?

I recently had to deal with exactly the same scenario with a 12" Danielson that a friend sent me recently. He had it in his electrolysis tank for quite a while but it was still frozen. I saturated the adjuster with penetrating oil repeatedly and began tapping on the moveable jaw in both directions over and over. I also gently tapped on the adjuster itself with a hammer and small punch. After about 3 hours of this procedure the adjuster finally started moving and I was able to get the screw to unscrew. The rust that formed between the adjuster and the screw could then be removed and it now works perfectly.

Or you could build something out of it !

Drill out the screw, and replace? Would let you access the rest of it.

Atf and wd40?

Those are cool.

Maybe temperature cycling too? A bit of time in a warm oven, then transfer to refrigerator?

That would be my LAST choice - NO, make it my Never choice.

The screw holding the adjustable wheel part on? Why never drill out? Should be easy to replace a grub screw.

****** tank. Take a look at the before and after pictures of this Ridgid pipe cutter I found at the local metal recycling yard. It was rusted solidly shut. I couldn't budge the screw no matter how hard I tried to turn the handle.

After one week in the tank not only did all the rust come off, but I was able to turn the handle with ease.

A little primer, a little paint, a little lubrication oil and viola!

They're sort of a special screw, you'd probably have to make a new one - you won't find them at the hardware store.

I rehabbed a little 4" Diamond wrench by soaking the screw and wheel with Kroil. It took a couple weeks; every time I'd walk by I'd give it another shot of Kroil and wiggle the wheel around, and eventually it all came loose.

I found one like that ,which had been half buried and outside in the Pacific Northwest for who knows how long. I got all the **** off the movable parts, tried pb blaster without luck. I eventually heated it up with a small torch and let it cool to the touch. That did the trick. Then oiled it up, now it's ugly but works great.

It is an electrolysis tank. I have a 12V, 6 amp transformer that I run in a tub of water with some sodium carbonate (washing soda) dissolved in it. The process removes rust--it's really amazing.

Have you tried "PB blaster" it's the best penetrating oil I've ever used. I don't know what they put in that stuff but it's even freed up seized pistons in motors for me. Depot even sells it now. Just look at the cans because there is different kinds of PB. Get the penetrating oil. Good luck.

Yah I lost one of those screws on a little 4" Crescent. Still can't find a replacement. It is a weird pitch shoulder screw. Don't drill it out.

Molasses bath for a couple of weeks.

It worked on a couple of Diamond adjustable wrenches my grandfather left behind when he departed.

 

[Cruzan80]

Ok, I stand corrected. Never had an issue for finding a replacement for one I had that was damaged, but I guess I got lucky.

I had several old Diamond Caulk & Tool adjustable wrenches, two of them frozen in place with corrosion. I figured they were a lost cause, but the other two I had worked so well (nice tight tolerances) that I decided to see if I could get them working again.

I soaked the seized-up wrenches in Evapo-Rust for an afternoon, then laid them in a small tray and sprayed WD-40 the joint area. I'd take them out, tap them gently with a (2oz. or 3oz.) brass hammer, drop them back in, and spray with WD-40 again. After three days, they both worked just fine, and would adjust through their entire adjustment travel.
