Let us see just one of your original designs of a piece of gym equipment. How can you tell if something is over engineered if you have not seen it working or have used it? Engineers and designers try to solve mechanical problems. Often there are several solutions to problems and the trick is to find the best solution that works. This is true of gym equipment. When you have a problem that no one has solved before it is a difficult process. I well remember having a chat with the head of the Mechanical Engineering faculty at Sydney University. He couldn't solve the mechanical problem of a machine that provides resistance for curling and simultaneously for twisting or supination. I was proud of my solution. I have seen another solution but mine is the most compact. I wasn't interested in making the machine flashy looking and complicated. I did use lots of stainless steel parts because I wanted the device to last a long, long time. There is only one such machine built that I know of.
First of all, that must be one of the most beautiful gym machine ever made with all that stainless steel, wheels and wires. No one can deny that, and it is obvious it hasn't been made by some impulse, but by long and hard planning. What you didn't know is the first rule of the engineering: When you find a way to do it, simplify it to the bone. That is when real engineering starts, and machines are simplified as much it is needed for production. That's why you don't see this kind of machines in any other gym. Think about it? What if you would have ability to simplify the idea for production, and you would have sell thousand of those all over the world? You would be a millionaire, not just some hasbeen with net worth of few dollars

Secondly, It would be nice to see even something this wannabe designer cockwave has done, not just hear that he is engineering genius in his own mind. Do we ever see that day? Nope. In the internet it is very easy claim to be anything, but proving things is far more difficult, because you can't prove lie to be truth. I mean any one can search net for different kind of drawings and plans, but only some of us, like Vince, can prove it has been done by him.
