Congratulations Arunion.
Hitting a rich seam of good form at last.
Your twin bar portal plate breaker was the cheapest way to clear the path. Although, Mark_man's use of tension/compression was also neatly cool.
I spent ages trying to find the best position for the cloth "return spring" - I so wanted to build the cheap transfer of Mark_man's improved version.
And although that 1101 tweaked version could have won, I was
never going to find it.
I quickly went away from using an "interfering" start position, because it made everything so tweaky and variable. Kudos for finding that.
A little tweak putting everything together is attached.
Couldn't get Arunion's geometry to work, but luckily there is another, even more effective way.... (same cost)
