The discussion focuses on mechanically producing modified SINE wave motion for a piston system, emphasizing the need for a mechanism that extends the time the piston spends at both the top and bottom of its stroke. Participants suggest using a combination of gears and eccentric hubs to achieve a smooth motion profile, referencing harmonic functions such as y = Sin(θ) + Sin(3θ)/10. The proposed solutions include using a crank with an N-tooth planet gear and a concentric fixed gear to generate the desired motion, while avoiding common divisor issues in gear tooth counts to ensure smooth operation.

Do you see anything in our responses that may have bothered the OP? The thread seemed to be going okay to me...Baluncore said:Under the circumstances, the trigger could be anything.
Likely. You are those most abrasive member I have found on this forum! Lol. J/K. I can't imagine you can be at fault. I might be though, stuff I say always gets taken the wrong way. And I didn't even post in this thread. That's how bad I am.berkeman said:Was it something I said...?
