geoffkait,
Since you seem to have experience with horizontal storage can you be a bit more specific other than your reference to mumbling?
jkbtn,
I use copper beading cones inserted in copper caps. I have no idea if brass will work as well. Never used brass. Give it a go and let us know how this works out. According to Franck Tchang, different metals give different results. Hence his use of various metals in his resonators. Although you may get good results with brass, of course you would need to A/B test in order to ascertain the difference between brass and other metals.
