This is a great thread! Thanks for sharing your experience everyone. I am tracking this because I have 2 saws that have what I call "Smokejumper Bends" in them. There is not a defined area of the saw that is bent, the whole saw hangs with a curve from tip to tip. I have straitened ones like these in the past by hammering them flat, very time consuming and hard (at least I am) on the saws. Could these saws be rolled to take that type of bend out? Or am I way off base?

If you could find a sheet metal fab shop with a wide roll would be optimum. In a saw shop we use the narrow stretcher rolls and roll multiple times to accomplish it.. smoke jumpers bend the saw in a horseshoe shape and it makes cross bends mid saw body. Long saws rolled into a crate tends to bend the whole saw and more so on the narrow ends. Both will be a lot of light hammering either way.

Hi this is brother ben. I have beentrying to level a 3 ft. crosscut saw. I can get it some what staight but then there is a few seys or teeth and rakers that bow out. I tried using one side as control and leveling it from the spine to the cutting edge,the whole lenghth.it gave a uniform bow the legth of the saw.i tried hammering the opposite side.i still cannot get the teeth in line.i tried to bend the teeth to conform,but made the rent worse.

The video has a pretty good description of straightening a saw:

Hi this is brother ben. I was wondering if saws were ground in a true taper or terised like a hill.or shelfed. When checking the saw plate perpendicular to the saw line I want to hammer it with no dishes or humps.my concern is I may make one side great and the other side will be wanting. Lord willing I'll read Johns instruction more attentive.and perhaps the Lord will give me understanding. Thank you your friend brother ben.
