  • This rake cam needs to be advanced slightly, maybe about 1/8". There needs to be a "kick" of the rake at 180' to release any pins to the pit that may have got caught with the neck pointing straight toward the foul line. With the way the rake is adjusted in this video, pins may be pushed back toward the lane surface.

  • That is primarily due to the rake cam being worn. The concept I was trying to demonstrate is that the rake is at an equal height on the sweep and the return at it's lowest points. This allows for the lowest possible adjustment to prevent deadwood calls.

    The place I am working at now is running at A speed or just below. I'll video one just for a "slo-mo" comparison. ;)

  • I love A-2 speed. Japanese A-2s however, are a bit faster then these still. Problem is with the speeds the Jap A-2s run at they tend to burn belts and bearings A LOT faster.

  • The speed difference is due to the the motors. Japanese electrical systems are 50hz, American are 60hz. This makes the Japanese motors run faster than they initially would, thus if you installed an American motor on your Japanese A2 it would run slower. Don't though! Those Toshibas are hard to beat!

  • @heavyq Slow them down then, I did to my 72

  • cant you just switch out the motor to gearbox pulley and the motor to elevator pulley to make it run slower (switching to smaller pulleys on the motor side)

  • I have that at my hometown bowling alley, But the sweep sometime got stuck by the pin machine. It was sooo badly...the sweep was cut half.

  • a smaller pully on your motor would slow things down and save a lot of wear and tear on your gearbox. I changed all ours over to Model A speed.... lessens the chance of worn 1-1 keyways.

  • My bad. They're AMF's.

  • Dude, that's fast! The Brunswick pinspotters at Cherry Grove Lanes take about 10 seconds to clear and load.
