AS PROMISED! AMF 8270 My video

[Phonetek]

So here it is folks, I finally took this today and hopefully it will answer many of your questions on how these things work. I'm sure you will have more but this should be a place to start, I tried to be thorough. So here go you, the AMF 8270 explained in action.

P.S. Please ignore my speech impediment, thanks

For those of you who take the time to watch it please let me know what you thought. If there was something I didn't show and you'd like to see let me know. Upcoming video's are going to be in depth on the lane oiler and automatic scoring / ball speed system.

Thanks Bowl, I fixed it. My others as well. Easy fix.

Well done Phoney!
I enjoyed seeing all of that stuff. Since you changed out brushes on the motor, I guess they're DC motors. Based on the size of them they're probably 3 to 5 Hp. There must be some power supply for them. The place you're at looks pretty clean! Nice! Some of the places I've bowled at around the area, the balls come back to you with all kinds of dirt and grime on them. When I get home, I take out the gear I've used that night and have to clean them for way too long; however, the house I usually bowl at leaves very little dirt or grime on my gear which makes my life a bit easier to handle. One fellow said that there are wheels that get the ball picked up out of the pit. Maybe they're after that sock thing you showed. He mentioned that most standard ball wheels are made of rubber or something, but the better equipped pin setters will use urethane wheels which tend to keep things a lot cleaner.
Since I dealt with lots of different types of machinery builders over the years when I worked for a living, your video was very interesting. The machinery I got to see were completely automated ones that were machine tools, packaging machines, textile machines, plastic bag makers, paper converting and wood cutting / routers. I even got to help some folks making big heavy duty hybrid vehicles. It was always fun to help machine designers make their machines work better and solve automation issues that they had to deal with.
Looks like you've learned a lot and have retained what you've learned, too. All those switches actuated by cams are pretty neat... Good luck! Stay safe back there!

Thanks Djp, actually the motors are only 1/3 hp, a lot smaller than I would have guessed too. The brushes are a breeze the change, they remind me of oversized zippo flints. There is 4 in each motor and they last only about a year. It's easy to tell when they need to be changed, the table will start getting jerky when it comes up to the rest position at the top. Once it does that you have about a week left before they fail completely and the table will slowly fall down over night. That's why we write the date on them so we know to start watching them closely.

I've learned a lot so far yeah but I probably know less than the main mechanic has forgotten at this point. I know enough to where the employees and manager can depend on me to fix most thing when the mechanic is off. Having a great instructor is the key. I plan on getting a video doing an interview with him too. He was out sick yesterday or I'd have done it. In that shop I took you in, he could name every part and probably the part number in the place. Oh and that "Sock" the ball goes through get changed out once a week, every Monday. We have 3 sets of them. After 1 week you can literally ring the oil out of them. They don't look like they do much but I wouldn't want to see how the balls came back without them.

I just hope my video was more thorough than any you find about them on youtube

[boatman37]

Pretty cool. Thanks for posting!

[TCJ]

I am permitted to walk in the machine area at my center, so I can (if I want) watch them in action. I've only gone back twice, however. I generally prefer bowling instead.

[bdpeters]

Very informative Phonetek. Much more detailed than many videos Imhave seen. Pretty nice to know what is going on behind the scenes

[jamoke]

Thanks for taking the time to produce and post the video Phonetek, well done.

I'd be interested in knowing how things go wrong, like when a ball doesn't come back, and when it does it's all messed up with gouges and belt marks etc.

Thanks again!

[Phonetek]

Well the belt marks happen when the ball lift belt gets too oil soaked and it causes the ball to go up and down a multiple times before it catches so it will leave the residue on the ball. Gouges happen if the ball door screw is sticking out too far or if a screw or other part had been sheered off or fell out and is sitting rolling around in the pit. If your ball gets damaged there IS a problem somewhere with the equipment or something is worn and should be reported to the counter so it can be looked into. That said, if you threw a gutter ball and it comes back gouged that's a different story.


BTW: Thank you all for the compliments on the video. I'm glad I was able to provide you guys some insight on the machines. If there are any further questions I will be happy to go back again and take more. I really enjoyed doing it.

Last week my BWG came back with a flat spot about 1" in diameter. Almost looks like somebody just zapped it with a grinder real quick. Barely able to feel it but it is there. It is just below the thumbhole real close to my track. I can't see the track so not sure it is actually rolling over it. Have not been able to see any oil on this ball ever. Even the new Rhino Black Pearl, no oil or track marks at all. And last week my ball was covered with belt marks. Looked like it was 5 years old when the night was over.

Damn dude, you have the worst luck with bowling balls LOL Do your lanes use AMF or Brunswick pinsetters? I can tell you that they are completely different animals all together. Much more mechanical than ours and I probably wouldn't know how to turn one on. I can ask the mechanic today what could have caused it for you though.

[boatman37]

Everything around says AMF so I assume AMF?

[Phonetek]

Yes Boatman, generally if it says AMF then it's AMF. In most cases the rake or sweep whichever you want to call it say AMF unless they covered it with something else. Qubeca is another name you will see which goes hand and hand with AMF but seems to go along with the scorers but I believe they are part of AMF. I could be wrong.

[boatman37]

Yep. I have pics of the scoreboard and it says Qubica AMF.

Then no bout a doubt it, it's an AMF house.
