[CW] Regarding the slowing down of bugs......

[Steve WD8DAS via CW]

I've never understood the idea of slowing down a bug by adding weight.  The swinging dit arm is a pendulum, and the period of a pendulum is controlled by the length of the arm, not the weight.  You move the weight farther back to make the pendulum arm longer and slow it down.  When you've reached the end you have to add an extension to the arm (which I did as a kid using the shank of a blank house key) to go even slower. 

On a pendulum wityh a small amplitude of swing like on a bug, adding weight without lengthening the arm will make it close the dit contact for a longer time, changing the length of the dits,but the speed would not be changed.
