I have a 36 inch length of .375 drill rod. It looks wonderful but has a bit of wow in it. I need a 12 inch length which I would like to be as straight as possible maybe to a couple of tenths. I would lke to hold one end in a collet and use it top align other parts of my equipment. Obviously if I know the eccentricity I could add/subtract it from my readings to arrive at the number I'm looking for in the setup, but...
My thought was that it would probably be better to straighten the entire lengh, then cut the best 12 inches out of it. I'm assuming that the bow (wow) is spread over the length but I'm going to set it up and indicate the length to see if this is true.
My plan if the bow is even over the length is to set it up in wood blocks on each end, and whack it with a mallet until it is straighter. Is this a good idea, or is there some other scheme that might work better. I could also use a clamp with a bar to more evenly distribute the force to squeeze the high side down.
I don't have a press.
How would you do this?
