I saw that too. It's what got me thinking about what I have around the house that I might make one of those with. That's when I stared thinking about the one handed clamps. Those adapted "vice grips" would put on a lot more pressure. The only advantage I can see to the one handed clamp is that I could make a fret press with "found objects" around my house...and I'd still be able to use the clamp as a clamp when finished. That is, if it would put on enough pressure. If not, then, once again, my penchant for cheapness would have bitten me in the trasero.
