I just started to give a Spanish Eyes the once over so see what needed doing as when I got it I noticed the ball count and match units weren’t moving smoothly when activating the plungers by hand. Match unit cleaned up fine. In doing the same to the ball count unit I’ve discovered the sprocket has a broken tooth on it. This means it will advance about 3 steps then stick. You can see the missing tooth top left in the pic.

I’m guessing there’s no real way to fix the broken sprocket so I’ll need a new one. Any ideas where? If anyone has one knocking around I’m happy to pay.

Thanks

I had wondered that myself after reading up a bit. However, it doesn’t seem to add up (literally!).....

With the unit fully reset so that the wheel post is opening the switch on the unit I can advance the unit 6 positions before encountering the broken tooth when it advances no more. The schematic shows 10 ball count lights so I’m guessing the unit should advance 10 steps?

Just realised the oic might have caused confusion. The flat at about 9 o’clock in the picture is indeed meant to be there. The problem is the single damage tooth at about the 10.30 position. Can someone confirm this is indeed damage and not be design. I can’t see its design as explained above but would like to be sure before I ‘repair’ it!

Thanks - I’m pretty sure it is. It’s make no sense to be stopping the unit at 6. I’ll have to look at doing a repair.

Thanks Mike. Appreciated. Looks almost the same but the length of the shaft/thread look different.... what do you think.

You can also see the damaged tooth easier now it’s off the machine.

Unfortunately the wheel has 5 ‘holes’ in which means there no where to put the post at 180 degrees. I guess I could move it to nearby and then move the switch it hits to compensate.

I have a contact who is a clock repairer near me. I think I’ll see if he can repair the tooth as the first and easiest option. Will let you all know. Thanks for the help.

Sadly I can’t test anything properly as the rest of the machine is stowed until I clear some space. Once I’ve stencilled the other machine I’m working on I’ll be able to check things out properly.

Yes I did wonder if it had been done deliberately at some point. Maybe to ‘solve’ a problem elsewhere. The machine was set on replay rather than add a ball so I guess the fact that it didn’t go beyond 6 wouldn’t have been an issue on the that setting?

I’m hoping to get the machine set up in the next few days so will see what happens then I plug it in!

That looks more like it. Here’s the measurements, all in mm. Thanks.
