  • Leaving cabinet hardwood top free floating .. is this ok?

    Hi,

    I made an entertainment cabinet out of maple plywood. It is has 6 compartments, 3 on top, 3 on the bottom. I glued up a solid maple top for it, and so I want to know if it is ok if I leave the hardwood top floating instead of screwing it to the cabinet? I will be placing a 50" plasma on the hardwood top.

    Regards,
    Gus

    I don't see any advantage to leaving it free floating. There's always the remote possibility that it could get bumped hard enough to cause it and your plasma to come crashing down to the floor. Is there a specific reason why you don't want to anchor it?

      The cabinet top is 3/4" thick, 63" long and 2" wide. It is pretty heavy enough that I don't see it being moved easily. I guess I am just concerned about the seasonal wood movement. I was going to fasten it in the front and then counterbore it in the rear and add some washers to the screws to allow for movement that way. So if I figured of I leave it free floating I would not have to worry about the expansion.

        2" wide? Two feet maybe.

          I would get a table top fastener like this:

          Or this:

          Both will let your table top move seasonally, yet still be attached.

            With uneven weight distribution, and the heat of electronics in some parts and not others, you run the risk of the top warping without securing it. Z fasteners, figure 8's or elongated holes all will work. If it is going to back flush against the wall, secure it in the back and let the front do the expanding.
            I think you may regret not going the extra effort to secure it now.
