I used 1/4 inch yellow nylon rope, length should be about 3/4 of the lement
length. Rope must have the room to "jump" inside, be free. Can't have it
tight or stuffed. The purpose is to be able to jump and work against the
vibration of elements. This dampens the oscillations. You don't need to put
it all the way to the ends.
End caps, if desperate can be made out of cork, buy bunch of wine bottles,
drink the wine, save the corks and you can cup and "sharpen" them to fit
inside of element tips.
