crosstilts/depressions and pinspots?

[shamefowjze]

just wondering how you guys fix the following items for certification. i've got a bunch of crosstilts and depressions to fix. i was taught to pull up the panel and shim as needed to get it into spec. some people have told me to shim the foundation instead. i have synthetics that were new at installed new when the building was built. also i got hit with a couple of pinspots. on single pins i was taught to shim the spottoing fingers as needed to get the pins on spot. i've heard of some people bending spotting fingers to get them to set pins right....how do you bend a spotting finger? maybe i'm just a puss [img]/content/btubb/images/%%GRAEMLIN_URL%%/laugh.gif[/img] . if shimming the finger is a bad idea how exactly do you go about doing it...just curious.

Re: crosstilts/depressions and pinspots?

I would make sure everthing is still tight,I always try to pull the lane down on the high side before shimmong the low side....as far as pinspots
I would never try to bend a finger(could crack deck). The suspect finger(s) could be bent causeing it to set offspot.Measure the distance between the rear web points of the fingers,this should measure 3" if it is wider than that one or the other fingers is bent.Remove the fingers and take a true flat stock and lay across the mounting surface of the spotting finger.You can tell right away if it is bent.I have also found that on some A-2s (with scotch yokes) that have been slowed down to A speed often fail to set a consistant rack.To help with this I set our deck heighth to 3/4" above the lane instead of 15/16"
This has helped us keep the pins setting a good clean rack.

Hope this Helps,
Peanut

Masternut:
I find it helpful to carry a new spotting finger, (both samples) and hold the opposite finger tightly to the base of the suspect finger, if any light shows through, I discard. Saves having to protect a true, edge bar in a traveling vehicle.
Agree totally on the slowed scotchers, versus spotting heights and the words of caution not to try bending a spotting finger.

It would be easier to change form pinsetters to pinspotters...LMAO...sorry Masternut.

Had a couple "high" spots out of tolerance on our synthetics...I just stood my fat a$$ on the lane near where the measurement was taken and voila!! Everything is in specs.....LOL

just gotta be careful I don't eat too much for lunch or I'm out of tolerance the OTHER way!

couldn't resist guys...

long live the USA

It actually matters if and where the inspectors stand on the lanes as they measure! We had some non compliant readings on our Anvil lane when the installer came back in he showed how they complied if he didnt stand on the lane as they measured them.

Someone told you to shim the foundation? This sounds like quite a job.

I am new to this site and I like what I see!

I have to ask about foundation shimming because I have a similar problem. My 32 lane center is 6.5 years old. Both Lane #1 and #32 are sinking. Oh...I should mention...this is Brunsjunk Anvilane I am talking about. The 7pin side of lane #1 has dropped about 3/8" and the 10side of #32 has dropped about a 1/4".

As you can imagine it is hell bowling on these pairs. I have shimmed the lanes into compliance but now I am getting depression problems.

If anyone has experience with shimming from the foundation, I would sure like to discuss this possibility.

In my experience, shimming Synthetics between the press-board(or old wood lane) and the panel, causes as many problems as it solves. As time goes by, you wind up with humps, bumps, lumps and moguls looking more like a ski slope than a bowling lane.

So...Anyone with experience in foundation shimming, PLEASE reply. Thanx.

This is a PHAT web site!

Re: crosstilts/depressions and pinspots?

I have shimmed brunswick synthetics,anvilane and found that any depressions that were fixed caused good parts of the lane to be out of spec after. one lane in my last centre was that bad that we ended up shimming from approach to the tail plank!! to get it right. As for foundations i havent tried and dont really want to try. Not to mention real sore knees after a lane or 2 [img]/content/btubb/images/%%GRAEMLIN_URL%%/mad.gif[/img]

Re: crosstilts/depressions and pinspots?

If you have overlays...shimming can be done to eliminate crosstilts by shimming the old lane bed. Easily accomplished when comparing to trying to shim the foundation. Depressions can ONLY be solved by shimming the area of the panel that is too low. Lift the panel and slide a shim under. I have shimmed panels for 10+ years and have yet to see...humps, bumps, lumps and moguls looking more like a ski slope than a bowling lane. If it is done properly...you'll never see it.

Pinspotting-If the moving deck is bowed, you can replace spotting fingers all day long and never get it right. Your first check should be for a straight moving deck. Then go after your spotting fingers. Zot sells a very good kit for straightening a bowed moving deck. Also, check the deck roller itself...if it has a flat spot on it, this could cause the pin to be slightly off-spot from time to time. I also like to go through the machines the night before inspection and apply a light film of lane oil to the spotting fingers just to help them guide the pin with just a little less friction...but thats just me.

As far as an inspector standing on a lane while checking for cross tilts and depressions...first point out that he is doing it improperly. Inform him that he is to straddle the lane with one foot in each gutter. If he disagrees...find the leader of the group. Point out the problem, and if that doesn't solve the problem, just make notes about the problem and call Wisconsin as soon as they open and talk with the certification committee and let them know what was wrong. Let them know you pointed out the problem to the leader of the group and that you dispute the findings because of the inability of the inspectors to perform the job correctly. We are paying them to do this job, and it is our right to have it done correctly.
