See next post...
I was totally lost until the 10th post.
So the hole in the center of the table is too large.
Simple:
* Clamp a 1/16 drill bit in saw blade clamps.
*Tape the bottom of the hole shut.
*Mix up some plaster and pour it in.
*Tape playing card on top.
* turn saw on slowest speed until plaster hardens......
Let me know, seems like this is as good as a Ace of Hearts, cardboard box, fridg magnets and packing tape
Lets see.
