Johann E. E. Bessler and his clues

Maybe it might run if you could find a way to extend the linkage using the weight of the entire wheel instead of independent weights that will end up as a counter balance to stop the rotation.

there is no question of it rotating I have not shown the peg or its position as i need a model to try it but the peg when it is at 6 o'clock and fully retracted to the center will hold it there till it passes 12 o'clock then releases it to extend to the edge of the wheel on the descending side as described by witnesses on besslers wheel, as i said the key is the PEG and the slowing PENDULUM not shown.

I did some calculations on this some time ago and found that multiple scissors also increase the leverage on the extending weight.
I was thinking that in the end it would be a wash on any gain for rotation. I hope I'm wrong about this.
Did you do any calculations yet?

At the time I was drawing up something for a simulation but quit after putting some thought into it. (maybe not enough thought!)
It's possible that the extension could offset the weight far enough to rotate the heavier weight doing the extending.
Even the single stage setup offsetting the weight further out on the wheel may provide more gain than the same weight moving the same distance but closer to the wheel center.

this is it, for sure. thx

I think the balance is very important as well as the scissor cross piece lengths Bessler seams to draw them with a longer cross pieces at the heavy weight end  going to smaller at the extension end could have a bearing on it and also don't forget to factor in the weight of the extension arm itself as it is fully extended, the calculation should be made from the axle to the small weight end, calculations are not my strong point but i understand the mechanics.
I think the aim is to have enough heavy weight to extend the arm with the minimum movement of the heavy weight, and i am also having ideas about the pegs if one side of the axle is fixed can put a small rod  or two  at specific points to set the peg and hold the arm closed on the ascending side and another to release at the descending side
that could be where the springs come into play to do with the setting releasing mechanism on the pegs.
