Mechanical Engineer friend contacted about the rotating carousel and incorporation of a small music box player with subject appropriate music. Being a Mech-E, I suspect I will get the design drawings and information in about 7-10 years. I'm still waiting on a rolling bullet trap for the garage...........he has designed, built, and tested at least 8 designs to date. None of them made him happy enough to share the info yet.
That was 4 years ago.
Basically, I am on a breath hold for the spinning, singing, LED lighted carousel of JMB goodness.
