Flattening bar stock?

[Altofsky]

So Ive been getting some of Aldos 1084 and love working with it.

Only problem is, the four foot lengths often arrive bowed in the center.

How do I correct this? Throw some weight on the center? Flat sand? Kinda at a loss here.

as you cut the bar into smaller knife sized sections the bow will become less pronounced. say a 4 ft bar has a bow of .040 then each foot section should have about a .010 bow or there abouts. at my job weve received bowed material and fixed it by placing a brick on the arc of the bow and heating the bar from beneath. you can get it pretty close that way and then when you part it out itll be easy to get flat with some emory paper and elbow grease. also, it costs a little more but if you buy precision ground stock youll have no worries. i hope that was helpful, good luck. leif

I must be the odd ball.....I just put one end on something on the floor ( piece of scrap wood, metal, pine cone, etc.), let the other end sit on the floor, and step on the bar in the middle.

Lay the bar on a thick, solid board of hard wood - bowed center up - then smack the heck out of it with a wooden mallet along its full length until the bow is gone.

If a bar isn't straight, I put it in a vice and bend it until it is reasonably straight. Then after I profile the blades, I always straighten them out with a 2x4 and an anvil. After I grind them, I straighten them out again using the same method.

Thats way to simple Stacy.. There has to be a better way.

There is a better way. I just buy PG A2 and it comes flat. . Not really what the op was about though......
