    as ive posted ive been coldfiring my blades. had one that needed straitening but figured id do it when i got it back. bad idea.
    so far a 3 lbsledge,front of my truck and vise still cant bud it.
    dont know what the moral of this story is but i hate to heat it
    as that reverses the process.

    Any bent blade should be thrown away.

    awm, i don't think i would want to use a blade i had tried to straighten, but as i understand the cold treating process, it is permanent unless you take the steel back to a molten state. i could be wrong on this, but i believe i read that somewhere.

    I would of gotten new blades for the coldfire. I wouldn't straighten them. Remember the BIG thread on that last winter?

    I'd say its "well done". (pun intended)

    I noticed at NAPA yesterday they have blades for most all mowers. I saw all the commercial mower blades listed in the parts book. Just thought people might like to know this.

    awm--seriously, what do you expect from a blade?

    if you conk it on something why wouldn't you expect it to be toast?

    many years ago, about 1978, I had a lawnmower with no governor and I was reclaiming grass from the woods.

    I called this thing "THE PUSH HOG"! when I'd bend the blade or bust the half moon key on the crankshaft, I'd fix it. a propane torch, a big ball peen hammer and a rock did nicely with a new key.

    I see no point for any professional orgnization to do this. buy a new blade.

    coldfiring? does this kick up the rockwell hardness of the steel in a blade to hold the edge longer? can I do this in my oven/ freezer? I am half serious. Dave g
     
  10. Done that. Been there. Watched part of the blade fly down the street. BAD idea!
