My first attempt was to make L shape desk. It went very well. I used two Ikea table top Lagkapten 78 by 23, making it 100 by 55 L desk. Used 8 10 ft 3/4 pipes. Came out to be 180$ total to make the desk.
OK. I see the two 45° on what might be called the outside edges, those towards the back wall and the guitar. I was wondering about the inside edges in regards to how much weight they might support, because 100" is a fairly long span.
Robert Muzzy Total weight combined on the table top would be 44 where inside you are referring is very solid. I originally had some concerns too. But once I built and tested it out it can support much heavier weight. I sat on it and I am 175 lb.
Building something similar but currently I was thinking about a kitchen counter butcher block and using 1 inch conduit. However I might like this idea better if it isn't as heavy as the desk I am making will be on wheels.
