    Piston Sine waves
Click For Summary
The discussion focuses on the mechanical production of modified sine wave motion for a piston, aiming to extend the time spent at both the top and bottom of the stroke. Various solutions are proposed, including the use of gears and eccentric hubs to achieve the desired motion profile, while avoiding electrical solutions. The conversation highlights the challenges of maintaining smooth operation without oscillation at the extremes and the importance of gear tooth counts to prevent wear. The original poster expresses frustration with the forum's atmosphere and decides to leave, citing derogatory comments. The thread concludes with a recognition of the complexities involved in designing the mechanism.

Under the circumstances, the trigger could be anything.
We should pray for an early monsoon, and a welcome back.

Do you see anything in our responses that may have bothered the OP? The thread seemed to be going okay to me...

There were the usual "reading and understanding the question" problems, and some wrong assumptions while "getting to know the OP's capability".

It was typical light-hearted banter, in parallel with the topic, nothing directly personal, but our interpretation is not subject to the stress of inescapable and debilitating heat.

FWIW, I did get the impression that this overall thread was being rather more derogatory/aggresive than usual here.

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.

Seriously though, some people just have a thinner skin to start with...
