Topic tags/keywords: saw blade rust

I have Forrester Dado King set. Just before I moved from Illinois to Oregon my son hit a brad while cutting a dado. This triggered the SawStop brake (perfectly). Had to replace brake of course but what about the blades? I talked to Forrester and they suggested checking them. So I shipped them to Forrester. They reported the blades were fine and sealed all teeth on a thick plastic.
But as soon as I had the blades back we sold our house and moved. Buying a house, some health problems, finishing the shop and lo 2 years have passed. When I got the dado set out…. OMG!! The blades had rusted because I forgot to wax them.
Now I’m removing all the rust but the blades are still dark and stained. I’m thinking brass brush and a lot elbow grease but if folks have a better suggestion I’m all ears. Tia

Cut some wood with ‘em. Will take the rust right off..
Or dunk ‘em in evaporust for a bit.
Keep in mind – they don’t gotta be pretty to cut wood.

Cheers,
Brad

Contact Forrest, they may have a suggestion. I always heard people in Portland don’t tan, they rust . I guess that applies to blades as well.

Ric, I’m on the east side. I’m a big fan of Evaporust and a brass wire wheel on a grinder. First though I get one of those brass wire tooth brushes and make sure to give those blades some very loving TLC.

2nd for Evaporust, used it to restore a 1950’s RAS it’s amazing.

I think if they’re just dark and stained, I’d leave them alone. Like Brad said they don’t need to be pretty. Besides the next time you have them sharpened they will likely come back clean and shiny.

Just to close this out, I got Evaporust and immersed all the blades for 48 hours. That removed all the rust but left them coated with black grime. I ended up scrubbing them with a Dremel tool and 3M style Scotchpad material. Worked well:

I stayed well clear of the actual teeth but I figure the wood will clean the teeth.
