  • 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.

                When a work lifts your spirits and inspires bold and noble thoughts in you, do not look for any other standard to judge by: the work is good, the product of a master craftsman.

                  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.

                      I understand supporting the magazine and agree. I just do not find many projects that fit my desires.

                      I would like to see them do a poll with subscribers to find out what type projects people want to see....

                      First off how thick is the board you cut?
                      When I want something to stand out I use backer-boards 1/8 thick to get the depth.
                      that means you would have to cut the big cutting into pieces to put the spacer behind.
                      for instance the cloud bottom right which his hand is on I would put maybe...

                      I am stunned at the fact it wasn't rotted or termite destroyed. That must've been one blessed lady. Thank you for what you all are doing!

                      Pretty boards. Our Walmart didn't have any when I went. Thank you for sharing though.

                      Looking at the image, I would sand down the clouds a bit on the left (as you're looking at it)....to make it look like the clouds on the right are the closest to you. Then with the clouds to the left being less pronounced it will make it look more like he is sitting on them. Humorous design choice...
