Its called a learning curve. Greg want a pool table that had no metal castings, no plastic pockets, and nothing sticking out above the finish of the rails that could scratch a cue, or cause you to have to bridge over it. Pocket designs were trial and error, rail designs too. Diamond wasn't even building their tables to begin with, Stapleton billiards in KY was, that started in 1988. They came a long way on their own until I met up with them in March 2000, and that was because I had heard from Global Billiards that a company called Diamond was trying to build their own coin-operated pool tables, in which I just happened to be looking for a manufacturer to build my designed coin operated pool tables. So, I met Greg in March 2000 and the rest is history.
In early 2010 I rebuilt the GC1's at Malarkey's Pool & Brew, using the same cushions and cloth Diamonds use, only they out played the Diamond red label tables Diamond was building, as verified by Dave and Oscar who owned the Golden Fleece Billiards Poolhall, who came to Malarkey's and played on the rebuilt GC1"s for 4 1/2 hours, to which they later called Diamond to complain about me rebuilding GC1's to outplay the Diamond 9fts they owned. That's what lead to the changing of the rail design to the Blue label rails, I had to fly back to Diamond in May 2000 to show the factory how I designed the GC1 rails to play better than the Diamonds played. The rest is history, but as some people here on AZB, say, I've never accomplished anything!!
