This stand is designed using the principle of tensegrity(definition below). The strength of this stand will surprise you. It can hold considerable weight. I used fishing line for the cables.
I built this out of 1/4" thick Baltic birch plywood. This was a prototype to see if I could make it work. If I were going to build one of these as a showpiece I would use a nice hardwood.
When you build this project, you do not need to use 1/4" thick wood. Any thickness will work. This project is a bit touchy to get adjusted level. I included basic build instructions in the pattern. They are just get you started instructions. You can use any technique to attach the cables. I used pre-drilled holes and small screws. When I adjusted the tension on the side cables I used push nails in the top to hold the line in place. I then added a drop of CA glue under the top at each line. I left the nails in place. All of these could be made using hidden techniques to eliminate the visual screws and nails.
Tensegrity, tensional integrity or floating compression is a structural principle based on a system of isolated components under compression inside a network of continuous tension and arranged in such a way that the compressed members (usually bars or struts) do not touch each other while the prestressed tensioned members (usually cables or tendons) delineate the system spatially.[1]
The term was coined by Buckminster Fuller in the 1960s as a portmanteau of "tensional integrity".[2] The other denomination of tensegrity, floating compression, was used mainly by the constructivist artist Kenneth Snelson.
CNC Scroll Saw. You have got to see this.
This is a, not ready for primetime almost working CNC scroll saw prototype. Andrew has gone through several revisions and is learning a lot as he goes. I know we can all see plenty of issues with this project but I give him an A+ for inventiveness.
One of the first things you are going to ask about is why he is not using a spiral blade. The spiral would make the control code and the mechanics much easier. He tried the spiral blades but of course, the cut quality was lacking and the kerf was too wide. His goal with this project was to cut puzzles. Kerf width is critical for puzzles.
Don't try too hard to think of this as a practical saw. It can not insert its own blade into an entry hole so that mostly rules out fretwork. This is the kind of project that shows today's maker movement well. Andrew is using all kinds of fabricating skills and maker tools(3D printer). He tops that off with his very impressive G-code programming skills.
