Cam Question

[cdsand5]

How do I use the go/no go gage on the sweep/table cams? I am having pesky issues with more than 1 machine not switching back to first ball from time to time and I know its in the ta2/sa circuit and I want to make sure the fingers are set right.

On the small part of the cam......the small end should not open the switch....the large end should open the switch

[Pin_Head]

When you do what King said , make sure the flat spot of the cam is vertical

Also, very important if these are SS chassis/Omega Teks, as the table is coming home you must clearly see TA2 press in the switch BEFORE TA1 otherwise it will have problems changing ball cycles.

I took an old 7/16 wrench and cut one end off. Using a micrometer I ground the end down to match the gauge. About 1/4" of the narrow gauge then 1/4" of the wider. I use the wrench to loosen the jam nut, slip the other end in, check and slide it to the next step instead of flipping it end for end. Tighten the nut back up and it goes back on the wall with a few other dedicated tools.

Sorry its taken me so long to get back on this but we are in the midst of renovating our game room, roof repairs and in a couple of days we are getting SPLs and I am being pulled in 35 different directions. I set the cam levers with the gauge on my 2 most problematic machines and they worked for 6 days with no respots at all but when I got in today there were 9 respots on 13 and 7 on 20 last night for league. My chaser sat and watched 20 set a full rack, the bowler left the 2 4 7, sweep went to guard then swept the pins off and set a new rack. I have changed out both machines micros with their sister lanes so I know they are good. 20 is a recent problem child but I have been dealing with 13 for over 2 years now and I am about ready to start swinging my 20lb sledge at it.

Are any of the springs on the cam fingers stretched?

This is the problem 88% of the time. Timing is so critical.

On the machines in question, split the gap (TA1 & TA2) that they trigger by an 1/8 of a turn in opposite directions. insure that TA2 clicks first. See if that don't cure it.

Hooooooold on there now. There is always a cause, ... somewhere.
Can I assume that in two years this machine has had different chassis on it, and the problem stays?

We have the brightest minds in bowling machinery all right here, we'll help you figure it out. The bowlers will think you're a damn genius! We won't tell.

Would the sweep start switch on the top sweep arm have anything to do with it. Maybe the sweep is bouncing enough when it comes up from second guard to double trigger the start switch and throw the cycle off.

That's an Accuscore thing and tells scoring when cycle has started. (timing for pin scan) If that were the issue, mis-scoring would be the result. With scoring connected chassis, short cycle will stepper the chassis into 2nd ball. So there is a possibility this could be scoring related. When you get a problem that you just can't figure out, anything is possible.

TA2 definately is closing before TA1 and my initial thought 2 years ago was a chassis issue but after 2 years and 3 chassis swaps the problem remains. They will work for a few days with no problems at all then they decide to act up for a couple of days then they will be quiet again. As for the sweep start switch, I do not have them. I will split the gaps in a few minutes and will update you guys on the progress.
As for the bowlers thinking I am a genius, they will just be happy to get the SPLs in. We are the last house in town with wood lanes and I hate to see them go.

[Tablejam]

So sweep went to guard, time delay, then swept pins and spotted new rack....that sounds like either a foul or second ball cycle. I am willing to bet it was a second ball cycle due to the TA1/TA2 adjustment we have mentioned. So it is not a failure of the respot cells or anything like that, it seems its a failure to change ball cycles....OR.... we have this wrong and its actually running foul cycles. The only way to be sure what it is, is to actually see it happen. This is one of those things that will screw with you. Have someone watch the ball lights on this lane as someone bowls, every cycle, until this happens, then you will know.

[keeth]

TJ I fully agree with your second ball suggestion,on a foul there is no delay in sweeping the lane it is just drop and go in one motion.

After the new set, What ball is it in? If 2nd it could be getting a foul signal.
