    Default "F" Type Quick Release Clamps

    I have a few of the "F" type Quick Release all metal clamps (non branded Asian crap) that won't hold under pressure. I'm considering notching both edges of the bar with some hacksaw cuts.<?xml:namespace prefix = o ns = "urn:schemas-microsoft-comfficeffice" /><o></o>

    <o></o>

    Others must have experienced this problem... so I'm wondering what you have done?<o></o>

    Thanks.<o></o>

    Drill a small say 1/8 hole at thread lengths along the bar.

    then use nail at back of slide

    Thats what half of my old clamps have, either hacksaw or old slim taper file to notch the edges(more control), works well enough.

    Default What to do with slipping clamps:

    Take a firm grip of the clamp in your dominant hand.
    Bring clamp up and over shoulder
    Bring arm forward smartly and with maximum force
    Release grip on clamp when arm is at or near full extension
    Make sure you're facing an area clear of breakables or people

    It won't fix the clamp, but it will make you feel a lot better.

    Repeated belting with a sledge hammer will also really show it who's boss!

    I have actually thought about doing that Mike (LOL). But then I thought I should pose the question on this site beforehand.

    Rod,
    you can file grooves that will minimise slippage. I'd stay away from the holes and nails, worked with a guy that had really dodgy clamps with this treatment, invariably you're in a rush when clamping up so the end result is nicked and scratched hands from the nails (or worse still, full on punctures :mad: ). One of his clamps ended up being thrown in the drink when it bit the boss.

    There a heaps of "new generation" cheap clamps out there now that work.
    Give the dodgy ones the heave.
    If they are smalluns the jorgensen coppies from carbatec are about $8 to $12 each & arent bad at all timbecon do simialr ones.
    If they are biguns carbatec have some big blue f clamps from time to time that are cheap as chips & seem to work well .
    I even got some biguns from super cheap that seem to work ok.
    cheers
    Any thing with sharp teeth eats meat.
    Most powertools have sharp teeth.

    Abrasives can be just as dangerous as a blade.....and 10 times more painfull.
