bullchuck,
I am wondering about the spring you made. Did you need to heat treat it. I have never made a spring before.
I purhased a postvise at an estate sale several years ago for $10. While I was paying, a man walked up and asked how much it sold for. He then went on to tell the seller it was worth $100. The seller said "well, its been here for two weeks and no one wanted it." I offered to let the new guy buy it for $100 but of course he declined. I was very happy with the $10 deal.
Another vise is available without a spring. That is why I am asking about how you made the spring.
