    Default Holding irregular material off the end of the table

    We have some projects coming up where we need to texture the top and sides of some irregular shaped pieces. We could use some ideas about how to hold the material when we are hanging it off the end of the table. Unlike a flat board, these pieces present some challenges for clamping. See the photos below which show the backs and undersides. Note that these pieces are supplied to us already assembled by the cabinet maker.

    Some kind of overhanging custom vac jig comes to mind.

    If holes in the backs are not a problem I would screw them to 3/4 inch plywood which I would then screw down to the table. That is if I correctly understand what you are trying to do.

    What about something like a slot and biscuit?

    Scott,
    The vac jig is a possibility.

    Lorin,
    Sorry, we can't put holes in anything so clamps or vacuum are about the only options.

    Chuck,

    Can you explain that further?

    Chuck,

    I like the slot/biscuit idea but it sounds like a no go since they can't put holes in.

    How much cutting are you talking Randall? Maybe just some good carpet tape would work?

    @ Randall and Michael,
    This spring I had the good fortune to install a Trex deck on a dock for a multimillion dollar home.
    I say this tongue and cheek because the process was a female canine.
    Recently, I was at another home job for a different issue and noticed the customer had installed the same type if Trex decking I had worked on. However, the installer had used a biscuit joiner or a router to cut a grove in the edge of the plank. (Like tongue and grove) The groves were cut where the supporting beams crossed underneath. Inserted was a piece of what looked like really strong plastic, ABS or some such.
    A biscuit!
    Only one screw held down both boards.
    Being part machinist, on the verge of buying a bot and thinking about hold downs I immediately saw value in the system.
    Up to that point, I hated Trex because the dang Trex screws break off for no reason, the bits provided fracture marring the surface.
    With this system, nothing gets marred. If you are gonna do Trex...this method works well.

    If you can or can't cut slots into the edge of your material ..........
    Consider some version of this:

    Plus....who was the guy here selling the wooden cams with the aluminum inserts?
    That was a heck of a good system!

    Welcome David!
    I love those things!
    Sorry to admit I stole the idea for use with some oak pallet material.
    We were having a tough time with some pricey tongue and groove being damaged by smacking during to 0ºf freezing weather.
    I made some 3' long cams with a metal insert and a big screw and we were able to force the tongue and groove together with no damage.
