I've since built several wall mounted RBS's. This one: http://www.youtube.com/watch?v=oOelpqNLT8A #79 and this one: http://www.youtube.com/watch?v=9iSm9TVWUvc #81.
Now these two wall mounted sculptures have a little story behind them. When I built #79 the buyer wanted a sculpture like #69 (http://www.youtube.com/watch?v=BSpbsehaJLw) - and I didn't clarify with the buyer exactly what he wanted... So I built him a wall mounted the same size and with the same one slow track. It came out fine, but when I talked to Greg he was a little less than happy and explained to me that he wanted a copy of #69. Apprehensive, Greg asked what we could do...I cheerfully explained I'll just make you another. And that's #81. If you look, it is a pretty close approximation of #69, maybe even a little better... : )
So I sold #79 made him #81 and Everyone was happy!
And for anyone who is following my progess on sculptures, #80 is on hold for the moment.
