  • Mounting a bench vise to MDF

    i built a workbench recently, and the top consists of a series of 2 X 6's and on top of that I layed a 3/4" MDF sheet (with paint and about 8 coats of poly).

    I really need a bench vise, and was wondering the best way to install it on top of the MDF. Should I use some ply underneath it or something?

    I'd probably use a sheet of plywood or a metal plate underneath the MDF if you intend to do some really heavy stressing on the vise. The MDF is pretty strong, compression wise, but I can visualize some tearout on the bolts it the vise is subject to twisting or prying. Otherwise, just a good set of large washers would probably be sufficient.

    I hope this helps,

      Thanks for the assurance, can you get steel at the hardware store? I was thinking about stacking a couple pieces to make it easier to cut/drill.


      I was thinking about getting some plates cut and sandwiching the top and bottom like you said, but I'll have to find somebody to do that. And without a doubt, I'll be using the extra hardened nuts and bolts.

      I really want to be able to bend things back using the vise, so I'm not afraid to approach overkill

        You just need one of theese for your vise.

            Cheeky, if you want one just PM me before you come to MA, and I will make it for you. It also has a piece of 2"x2" square steel welded to it so you can put it in your reciever hitch as a do not tailgate device.
