Just had Jack Zimmerman from Indiana come over to Peoria,Il and work on our 5 Gold Crown 9' Tables. We had the subrails extended and recalibrated, pockets are now 4.5, new GC IV pocket liners, upgraded to the threaded rail bolt inserts used by Diamond, Artemis Cushions and Simonis 860 HR . We could not be happier with how they turned out. If you need ANY work done on your tables, Jack is the guy. I believe he is a member on this board, so look him up.
