Are you aware of the Roller Chain Parametric Design (old I know but still appears to work)? https://forum.freecadweb.org/viewtopic.php?t=18267

With double pulleys I presume you are transferring lots of power, typically a tensioner is designed so that it tightens the belts on the pulley, this design kind of does the opposite. Tensioners are also placed on the slack side. Just thought I would bring it up.

thanks for the information. the original construction is not mine. I prefer moveable waves
