Always a good idea to invest in H.D rollers on the 7-pin side. This in conjunction with EBN blue guide rollers, it's pretty much a set it and forget it setup. Also, most ball wheels are not perfectly round anymore since they're so old. Always a good practice to set the guide rollers at the high spot of the ball wheel.
Great info in addition to the video. I hope everyone reads it. Mine (being from the early well built years) couldn't be more perfect but later years and quality cutting I'm sure there are some out of round ball wheels out there. Thanks for the additional info
@@GarageBowlingAlley My machines are s/n 13000 range. 30 lanes. Center was built in 1956. Quality isn't the concern. A not perfectly round B.W is a well known thing in the A/A2 mechanic community. Pretty sure it's even in the adjustment section in the service manual. You just got lucky with the machine you bought. FYI,im hardcore jealous of your garage! Love it!
