Thread: why didn't i do this before?!?!

firstly, let me say how much i hate c-clamps. they should all be thrown in a pile and burnt. that being said, i decided to see if i could make a air vise for my molds. i found the pneumatic vise on ebay for 10 bucks(25 to ship, yikes). i cut off the stop jaw so a block welded to the travel jaw could clear it. bolted it to the table, and then bolted a 4x6 to the table as a stop. hooked up a couple of check valves for pressure and pressure let-off. clamps 15 molds at a crack without flashing, and took me like two hours to redneck engineer. this is beyond awesome, and really saves the wear and tear on the hands. no more metal filings from the clamp threads getting wore out. no more messin around. two levers, and its pressurized or released in under a second. why didnt i think of this sooner? i guess i dont care at this point...im in heaven! it represents a pretty substantial increase in productivity, amazing how much time is frittered away just turning a c-clamp screw! brian
