  • Help with Load Ratings for Wood

    I realize this has zip to do with scrolling but I've had no luck in searching and asking elsewhere. I just received an order for a custom entertainment center. That's the easy part. The TV weighs 260 lbs. At one time I had a chart which listed different species of wood and the amount of weight they could handle without sagging over different spans. As this will be a black piece, I will be using oak, both for strength and ease of ebonizing it. The shelf that the TV will be sitting on will span about 4 ft (a little more than 1 meter for everyone not in the US, hehehe). I'm thinking 3/4" oak HVHC ply with a single reinforcement in the center of the span will be sufficient to hold the weight but hope to confirm this.
    Anyone????
    Thanks.

    Kevin, I would think with that piece in the center that it would be plenty of support. How will the ends be supported? Good luck with it.

      Thanks for the response Mick. Of course, you bring up the other challenge to designing this piece. They want it 6' high. I know a Dado isn't going to cut it (no pun intended) so I'm figuring out a way to reinforce the sides without detracting from the piece.

        Somewhere at home I have a fairly recent magazine that covers shelf spand loads. I will look for it tonight.

                  Thank you Marcel!!!! I have been using R. Bruce Hoadley's formulas from Understanding Wood to do the calculations. Quite tedious to say the least. Great site. It is now in my favorites list.

                    That is a very usefull link. The article I was talking about also took into consideration any edge banding you use to either dress up the edge of plywood or to add thickness to the shelf.

                    I looked last night and could not find it. I will look in the magazines electronic index to see if I can find it.

                      Cutting a straight line I get it started then plant my thumb at the side of the piece and use that to stabilize the cutting path, a bit like the pin you would use on a bandsaw when resawing old style.

                      We went to Groff & Groff yesterday. Purple Heart wood is stuck on a boat somewhere. They said imported exotic and hardwoods are stuck on boats. So if you see a wood you need, grab it while you can.
