Hell all I am in need of some help! I have acquired an 18" Frantom slab saw, and have completely refurbished it. When I got the saw it had three blades that were bent. I have bought two new blades, and had tow rocks get loose and bent them. Can anybody tell me how I can hammer these blades true again? Any help will be greatly appreciated!!!

OUCH!!! First, welcome to the board, and don't forget the o on hello next time! ;D They say you can hammer blades flat by laying them on a nice flat surface and hammer them all the way around the blade. I've never done it so I can't say for sure if it works, but it sure can't hurt to try. Let us know how you make out.

Wow. sounds like you have a real problem. I think Barranca Diamond products still has a blade straightening service, you might try giving them a buzz or try their rep, Dean Delahaut at: dean_delahautmkdiamond.com He should be able to tell you. BUT you really need to take a look at your saw vise, are the wooden jaws worn out? When you tighten a rock in the vise be sure you try HARD to make the rock move before you start a cut, if that rock budges at all- - tighten the vise even more! Sounds like you now have 5 blades that need work.

I routinely straighten my saw blades. I lay the blade flat on my garage cement floor and whack it with a plastic faced "dead blow" hammer. It works really well for blades with a kink from the rock getting loose. It usually doesn't work on dished blades because the blade metal is usually stretched at the dished area and is really springy. This is the same effect as is intentionally done in metal spinning to make a cup or bowl. Bob

I have hammered mine out on a flat cement floor using a wooden block and a framing hammer.
Barranca used to heat treat the blades and fix them, but they dont do that anymore as they sold their equipment. If you send a blade to them, they will hammer it out just like you would.
I agree with Jim, looks like you need to take a look at the vise, the rock should not be able to come loose. I tighten mine up with a cheater bar, that way it wont slip, and if the rock is fractured enough to come apart during cutting, it will break before I try to cut it. You may need to replace the wood on your jaws, they do wear out.
Good luck with it, those Frantoms are very nice saws.......................Tony

Bob is right, if the blades lose their tension you are SOL. Barranca can roll blades but no longer have a blade furnace so can't retemper. I'd try the hammer and see what happens. I have an old Highland Park and keep a box of blocks, wedges, etc. next to it. I use whatever works to secure the rock. Sometimes I use pine 1 x boards between the hardwood jaws and the rock to get a better grip. The wood in the jaws are rock hard. The most important tip is clamp the rock. Then grab the rock with both hands and try to move it in every direction. If it even looks like it wants to move you are not ready to cut.

Hello all
I have contacted Dean at MK Diamond. He told me that they have scraped their electro furnace, and no longer hammersmith blades. He also said that there wasn't anybody in the country that did it any more. He asked if there was any lumber companies in my area. Itold him yes. He then suggested that I try to find a company that hammers sawmill blades to see if they could help me. I have found a company that thinks they can get the blades true . I have given the blades to them to try. I will let byou know how it comes out.

Hello All
Well I have found out that it appears there is nothing to be done with the blades but to scrap them. I again want to thank each of you who offered help.
