Carbide Saw 4040 SE Division St Portland OR 97202 503-235-2260 800-760-2260
I got this from Barranca. I heard there was a second company in the Northwest also. Can't vouch for either but heard Carbide charged about twice what BD did. BD was losing money at what they charged.

I fix my dished ones myself using a hydraulic press. Works pretty good as you can control the pressure really easy with the press.
Good luck with it...............Tony

Tony, does that work if the blade has overheated and lost it's temper?

Not sure, I haven't tried it on an overheated blade. I do have an overheated blade in a saw I just bought, I was gonna toss it because it is almost done anyways, but I might give it a go.

So Tony, how do you flatten them with the press? I have access to presses and I have a few tweaked blades

Use some flat stock iron and position it at the start of the dish on both sides, then place a round piece of flat stock on top of the blade (about 2-3" depending on blade size) and use the press to exert pressure just slightly past center then release, rotate 90 degrees and do it again.
I have also used the press to take out loose rock owies out and press them flat again. Works better than beating it and is much easier to do.
I finally broke down and went and got my own press because my buddy who owns the shop that has the press I practiced with said he was gonna start charging me rent. I still use his big drill press though, haven't gotten me one of those yet.
I have been watching for some scrap pieces of large pipe so I could get some small pieces about an inch or two wide that I can use to support the blade all the way around so I would only have to do it once, but you would need a pretty good assortment of sizes to be able to accommodate different blade and/or dish sizes.

The other place in the PNW is Puget Sound Saw in Puyallup. Telephone number is 253 272 0661. They do good work. The first time I used them, I took a dished blade no one else previously could fix along with the new one I had dished. It cam back nice, and straight.

Woody, I think that's the place I have heard about. Tony, your method is the same way I press out bent extrusion dies at work. They have a set of rings but they only go to 12 inches diameter. They had rings bent and welded from 1/4 and 1/2 inch square bar then had them all blanchard ground flat and parallel. They also recently had all the 25"x25" platten presses ground flat so I'll try a few next week and see how it fares.

I just called Carbide Saw in Portland. They quit working on Lapidary blades a couple years ago, so BD better update their info. The place in Puyallup will still do it. The lady I spoke with was very nice. Prices I got were $69.50 for 24 inch $49.34 for 18 $44.86 for 16 For seriously bent blades they will charge extra. Not a bad price overall. They ship with UPS

BD gave me that info several years ago. I think BD charged $45 for an 18" blade but that included $15 shipping. They were too cheap but you had to wait sometimes a long time until they were doing a blade run. They had one giant furnace and couldn't run it unless it was full.

The old blade I took in was pretty close to being a wok, and they did not charge me extra. Woody

I fixed a dished blade once by heating it with a torch and setting a block of dry ice on it, popped it right back into shape.

I remember back when they made car bodies out of real steel with some kinds of dents we could heat them up a little with a torch and then lay a wet rag on it and POP!
