The first question that comes to me is, will it spin when the clays are shot off? The whole idea behind the texas star is that it start spinning when the normally large and heavy plates are shot off. I don't think that the clays are heavy enough that it will spin much if at all. I may be wrong. The other thing is that I think you may spend more time repairing the target holders than actually shooting at the star. I have got to say that you are to be commended for your efforts and I especially like the use of the Lexan cutting board.
I'll bet your wife will be looking for that soon though.
