[TheForge] Holdfast

[James Davis]

I bought from Harbor freight a drill press holddown (large one) made like a visegrip but with a nut and bolt to go through the drillpress table ...I added a piece of rod to the bolt making it longer so I can use it in the 1/2" prichel 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.
