Cool! Sounds very complicated for what it is, though. I don't see the reason for the cone-bottom, but hey, if ya got the time and tools why not? Instead of a cone, just slant the botton slightly toward one corner, and eliminate the sheet metal. Thats what I did, and it worked great. I also put a light in it. Heres the deal, I NEVER USE IT! With all the games I attend, the only I find myself practicing is transition and movement rather than pulling the trigger. Thanks for the heads up, though!
