Stringer Holes

[Louie_IV]

Does anyone know how to prevent the holes on the bottom of the bin stringer from breaking out? This seems to be happening a lot.

Re: Stringer Holes

No absolute here, but making sure your round 992 bumpers are in place will slow it down by absorbing some of the impact of the pins landing in the cradles.
To repair holes that are broken out clean and round, try Stahl's Tuffy Hole Closer kit. It consists of two washers formed like the indent area that broke out and overlaps the good metal. [img]/content/btubb/images/%%GRAEMLIN_URL%%/wink.gif[/img]

Re: Stringer Holes

Ya, we've used quite a few of the tuffy hole closers. We even tried spot welding every washer on to take even more pressure off of the hole. I was just wondering if there was a way to stop it from happening. I'm probably just dreaming though.

Re: Stringer Holes

I have only ever had this happen once in 8 years on these machines. All I did was use a longer bolt and a big washer to fix it. Welding seems like a good idea, but time consuming.

Re: Stringer Holes

Ya, it takes 8-10 years for the holes to start breaking out. But once it starts happening LOOKOUT!! [img]/content/btubb/images/%%GRAEMLIN_URL%%/eek.gif[/img] Seems like it all happened in just 1 year. Spot welding them is time consuming, we've only done it on 1 lane to sort of test the idea out. It hasn't been long enough to know anything yet. I know that the new stringers have the circular edge on both top and bottom to prevent this from happening, but who wants to go through and change ALL the stringers!

I have a guy sending me a sample of something that feels he has the problem solved...."better the sliced bread" is what he told me. He's a pretty sharp dude to so I'll keep you updated!

Re: Stringer Holes

Louie: How many machines do you have total? The reason I ask, for smaller houses, with older machines, few machines, but good income, consider building up a new bin assembly and start a swap-out with the bad bins. The parts will run you about $800 for the first one, then you can reuse parts from the first removed bin for the next, etc. It takes anywhere from 1 to 2 hours to build, and about 20 minutes to replace.

Second thought: Most of your breakouts are probably only in the center two stringers: at the 5-pin cradle where the shuttle spring is hooked, and the headpin chute tracks. We keep one complete center section built (2 stringers, 2 cradles, 5-pin guides, 2/3/8/9 pin guides, 2 butt plates). Takes about 45 minutes to replace.

Re: Stringer Holes

BowlEquip....We have a total of 28 8270's spread over 3 centers. One 12 lane center and two 8 lane centers. One of the 8 lane centers definitely doesn't have enough money to build a whole new spare bin assembly. Your right, it is the center 2 that are breaking, but it is also the 2 right next to those. I don't think they break often enough to talk the other 2 owners into spending that kind of money (remember, small centers) for a new bin assembly. Sometimes I wish we worked for bigger centers so they had the money to do that kind of stuff.

Re: Stringer Holes

BowlEquip probably has enough parts to build an eight lane center. [img]/content/btubb/images/%%GRAEMLIN_URL%%/laugh.gif[/img]
