Thanks for all the great comments!
To answer the biggest question, I have to say that the DOT spinner is the most functional spinner ever made. I have done my best to duplicate that exactly.
The feel of the DOT is unlike most spinners in that it actually has a 1/2" bearing and rotating sleeve. This gives the spinner a very heavy, yet smooth feel. In fact the original DOT is almost
too heavy, especially if it were to be used with multiple games. Obviously this was not a concern with the original spinner, but to be best suited for use in MAME and all the spinner games that are available I opted to lighten up the rotating mass just a little. I can't have BYOAC'ers suing me for causing Carpal Tunnel Syndrome.

Even still, this monster weighs just shy of 2 lbs. as pictured above.
If you give this spinner a good twist, will it spin for a very long time? No. Neither did the original. Again this goes back to the construction of the original spinner design, which I duplicated for the most authentic feeling spinner available.
The tension springs are stiff enough to not allow for up/down motion unless you intend to make those motions. My initial testing has shown that this spinner performs just as well, if not better due to the larger encoder wheel and tooth count, as the Pro spinner in "standard" spinner games such as Tempest.
This spinner also comes with my optic board which is compatible with the popular encoders such as the Opti-PAC and ME4. It also works with the optional USB mouse interface I have available on my website. For DOS compatibility you will need an encoder such as the Opti-PAC or ME4, or alternately connect it to a serial-ps/2 mouse hack such as BobA's or Minwah's popular examples.
And finally, Ray, I hope your daughter turns out much better looking than me.
