at least make a proper model or a 3d model or do a basic fea analysis to prove the point.

Why should anyone answer your questions if you grub for money right away at the mere suggestion of dissent? I see no benefit to the community--Pass. If money is your thing, you should have enough to just buy a Fisher and answer your own questions. Take care.

A volatile thought process is what I am observing. A contribution is not a contribution if one should bow down and express tribute for such. It should be freely given whether appreciated or not. Then it will be appreciated. That is the core of open source. Your time is really worth no more than anyone else's time. You insinuated that your time was more valuable, however, than those participating in the discussion. I realize that the response was that to criticism, and I personally have no problem with said drawing. But the nature of the response, veering in the direction of class conflict and self aggrandization, was not appropriate. I would have just said "can you do any better?". It may have just been that your brand of satire rubbed me the wrong way and I'll concede that's what happened.

sorry for being harsh. but if you were intending to contribute to the design a little more upfront work would help the process. most of the discussions are started with a little base work done. Sure you are welcome to contribute. and a person with a fisher would be in a better place to respond to your query,,
ps: you can easily grab the model from github to play around with . the fisher is a very good design if made out of aluminum or steel . the weak point is the acrylic and plastic joint

A real model is better than sophisitcated computer simulation. Ingenius people such as Buckminster Fuller developed quite amazing technology by using cheap materials that kids could access. Buckminster Fuller developed a floating building, Cloud Nine. The total mass of structure is lighter than lifting force of heated air trapped inside the structure. When the Sun comes up, heats up the air, it will rise over the ground like a huge Balloon.Quote
that's why i pioneered the technique of quite literally making the frame from drinking straws, paper, cardboard and tape. it costs practically nothing, and can be done in about 20 minutes flat. you can then go, "hmmmm....", chuck it away, cut it up, and within a couple of days of playing around have a really really clear idea of what the strengths and weaknesses of a given design are, and can compensate for them extremely quickly.

I upgraded the Fisher to laser cut 3mm to 5 mm steel plate. [wp.me]
The problem I experinced was the failure of plastic parts that join the steel plates.

I think to understand something, a model or concept, we gotta experince it thorough the whole senses - seeing, hearing, physical sensation by touching and playing with it.
