re split bearing:
Tornadoes have a great split bearing system for use in public venues on its tp coin and cyclone models, it provides a reasonable compromise for security against theft (about $50 per bar including men) but it often requires removal of a man and the handle to access and change a damaged figure. For home use, likely not much of a problem but annoying in the heat of competition. For commercial use it makes total sense.
The fireball design allows the handle to pass through and up and the men to remain in place to change an entire loaded rod. I noticed some the the fireball men have closer spacing and shorter rod length to allow the bar to pass out of the wall, this is a slight compromise if you wish to maintain tornado feel. The warrior has a lift out system which requires a wall cut out and bearing mount.
Sounds like Jim has set you up already, and using tornado parts is a sure bet. However, I think the space required for a Foosball table is a major consideration if you plan to sell these. If it can double as a bar counter or side table, it becomes much more accessible.
I'm curious in your estimate how much the total assembly of the parts and materials is costing? Too bad you missed that coin for sale in Squamish last week!
