Sculptural art often requires holding the work at various unusual angles. And it has to be solid, quite solid to put up with banging, carving, wrenching, welding, etc.
After many years of frustration trying to clamp things this way or that way and spending a lot of time re-orienting things between cuts, I decided to design something to sure that problem.
Having spent 15 years designing products, machinery, and processes in a manufacturing facility, I knew how to do it, so I dove in.
What I do at first on most design projects is build a proof-of-concept. That is, I hack together something that answers the question: Will this idea almost work?
The video below shows my proof-of-concept that I had hacked together out of miscellaneous crap I had tucked in corners gathering dust:
Once I knew that it would work, I began to refine it and clean it up. It's now designed in 3D CAD and I've had one set of prototype parts cut for it, and am in the middle of debugging the prototype design so I can move it into manufacture at some point.
It's called the PositionALL and it even has it's very own place-holder-really-doesn't-do-anything website:
