What could help with the strike deficit is to make the pin deck a LOT smoother. Pins just fall down. They don't slide around hitting other pins, which the smoothness can cause standing pins to slide and lose balance. You also don't have "Bouncy Stuff" (as famous candlepin bowler Marc Ricci would call it) on the sides, so balls and pins fly. They hit the side walls, and just drop. Lastly, you don't leave the pins in the setter long enough to stabilize, so the racks you get are poorly spaced. Minus the wind, movement will be about nil if held a second or two longer in the reset position. Still a nice setup! I just have freestanding stuff at work when "Driveway Bowling" on certain days.
Thank You. I'll try your suggestions. The deck is gloss painted plywood. I could smooth sand it and wax it. The strings do prevent some rolling. As for the sides, they are made of plywood. I'll try to find a rubber mat to glue to it. It's a lot of fun to play. You get interesting combinations of wood and pins.
