    Vacuum Rig

    OK, I have a decent vacuum pump......
    Attachment 12334
    ........and now I want to make a "Vacuum Rig", I've had a good look at www.joewoodworker.com and I think his article on the EVS Set Up looks like the way to go, at least the concept, if not the actual system.

    Some of the things he talks about in his EVS I'll get from him, as I have no idea where to get them here in Japan.

    I was wondering if anyone else has built this type of system and can offer some advice?

    I want to use it for a vacuum chuck on the lathe, and a vacuum bag for veneer.

    Cheers!

    BTW, the 20mm ID hose, I think they call it "Braided Tubing"

    I got for the vacuum pump, well, if I stick one end on the pump, and block the other end, the pump sucks it flat as a pancake in about 2 seconds......Maybe this pump is a bit too big???

    Thanks Tod, the "Weird Stuff" I assume you mean wavy, curvy etc, I imagine you are saying 20 mil (thinner) as it will conform better to the "Weird Stuff".......??

    30 Mil for flat stuff, OK, I get that

    I'll most likely order the bags from Joe woodworker, as I'll be ordering some other stuff from him, and shipping is always the killer, so I'll do my "Buy the best I can" thing. No sense in buying cheap, and paying for shipping, IMHO.

    Cheers!

    How much vacuum are you drawing? How much do you need to draw?

    A LOT Dave, this pump really sucks, it is not a small pump, but a large commercial one. I was told recently that they retail new, here in Japan, for about $3000

    Stuart,

    That looks like the same type of tubing I use, but mine is 1/4"ID whereas yours is more than 3/4"ID. Is there a reason you went with such a large ID? I've never seen a system, even in commercial shops, where anything larger than 1/4"ID is used. The larger ID tubing will be much more likely to collapse.
