I bought one of those too, and extended it as well. But I find mine
disappointing, and it often release in reaction to the shock of
hammering. It may be just poor quality control and I got one of the many
poor examples. But with the cheapy HF stuff, as always, your mileage may
vary...

>>> I have been trying to make a holdfast for doing hot cutting. I have the shape right (I think) but I am having trouble. The darn thing won't stay in the the hardie hole. I have tried several different tempers, everything from spring purple to just hardened. I can get it to clinch in the hole, but not on the piece I am working on. Once I got it to clinch down the piece of flat bar stock I was cutting and the Holdfast EJECTED itself up a good two feet in the air.
