Somewhere around 4 to 5 months after I got my rebel 17 the motor began making a humming noise. It has progressively gotten louder. It’s not obnoxiously loud but it’s definitely noticeable. It’s still working fine and it’s only running around 130 F, but this hum, to me, means there’s some kind of friction going on inside the motor. I think you're right about the heat in that motor velodromed, after reading your comment I checked the temps on both of my Rebel motors and they were both hovering at 86 to 87F in my cold basement which is currently 58F. I measured them with my cheapo-depot IR temp checker just a few minutes ago. Even my Lot-O is running cooler than 130F Did you get the new motor and what temp is that one running now? |

Cool… I just heard back from them and they are mailing me a new motor! I am liking their customer service so far. Damn, that is good customer service! |

I haven’t gotten the new motor yet. Still patiently waiting. 130f case temp is not hot for these brushed motors. They’re designed to run fairly hot. I wouldn’t start to be concerned unless it got over 150-160f. The real danger zone is between 180 to 200f, that’s when you begin to burn the copper windings on armature. When new it ran around 120f, even in my 95f summer garage. My garage is only about 75 to 80° currently. I’ve never measured the temperature on my Lot-o, but by feel I’d say its around 110f. I’ll check it later for fun. |

One of my Rebel's wasn't moving on Friday evening, broke my first belt and didn't have a spare on-hand. Ergh!! Ordered spares, sidelined the load in a bucket and waited. I took a drive on Saturday morning and acquired a replacement belt so it's back up and running now but not keeping spare belts on-hand was a valuable lesson. While it was out of commission it got a good cleaning and the pulleys got rechecked for alignment too. I'm crossing my fingers that it was just an anomaly.  |

How long was that belt in service? If you know the belt dimensions you can browse for alternate suppliers and maybe find one that's made of stronger stuff so it would last longer. I also found that buying them direct saves money. When the belt on my QT66 broke I was able to buy replacements from Grainger for about $7, when the lapidary supply places were charging over $10, if they even had them in stock... |

Mine is still running on the original belt. When it begins to suffer I’ll make a new one, which is easy to do with tumblers that use standard round transmission belts (not like the qt66 which uses a notched timing belt). I use 4mm round transmission belt off Amazon, cut the correct length then use my soldering iron to fuse the ends.  |

I lay my soldering iron down flat, pointed away from me, set at about 650f. I put the ends on both sides opposite each other, press them against the soldering iron while sliding forward till they met and hold firmly until they’ve set. Then I use a razor blade to trim it up. They’ve been lasting just fine. Sometimes I don’t get the fusion quite right and it’ll break at that part, but it’s easy enough to redo. |

I hope it's just a fluke too @hplcman but I'm guessing that I wasn't diligent enough when I originally lined up the pulleys. This belt made it less than a month and my 'other' Rebel has been going for 3 or 4 months on the original belt. Time will tell if I have additional issues but I'm betting my lackadaisical set-up of the device is the primary cause. (You know 99.879% of the time it's the nut behind the wheel) |

Their word is good and I just received the new motor. I’ll install it when feeling better then start researching what to do with the old one. I’ve heard about soaking it in mineral motor over night, but figure there are other ways.  |

I’ve heard about soaking it in mineral motor over night, but figure there are other ways. That's good news. Hopefully it's a smooth running (quiet) motor! Looking at that makes me wonder what the replacement cost would be. I ran the number a few times through Google and couldn't find a match for the frame and rpm. |

What is the motor rpm on the slower version? This one I just got is 1250 rpm, which seems pretty slow. I can’t tell on the old motor until I pull it, but can’t do that for a few days.
*Edit- I forget about Google sometimes. I looked it up and this is the slower motor, 1250 rpm. I turns the barrel at 20 rpm. So I got to think if I like that, or not. I got the fast motor that spins at 40 rpm so that I could use the thing to break down lots of rock that we find here in Texas.
Well, I’ll throw the slower motor on and see how I like it. I’ll have to change how I use the rebel a bit. Hopefully I can fix the old motor so if I want to, I can speed it up again.

So there's a fast version and a slow version of these Rebel 17's, right? Is the motor defining those RPM differences between these versions, or is it defined by pulley ratios? Maybe it's the same motor in both versions? |

Maybe it's the same motor in both versions? I understand that it’s the motor that determines the speed on these things. The 40 RPM one is technically for cleaning brass cartridges, but it’s still good for rough rock. Have to be careful with it though because it will damage rocks. So I’m starting to think the 20 RPM version may be really cool... once I pull the old motor I’ll be able to see the details. The label is underneath the motor so I can’t read it. |

I don't know much about the Rebel 17's, and have been enjoying learning from you and everyone else on here. Now that Lortone is closing their doors and there are fewer suppliers of tumblers out there I need to think about where I might buy my next one... |

I’ve thought of building my own eventually. But I’m still having too many nerve issues and pain to face a project like that anytime soon. I’m hoping next year. Meanwhile, I’m keeping an eye out on Facebook marketplace and flea markets. I have a couple of friends that have found high end tumblers for real cheap at flea markets. And I’ve done pretty good on Facebook marketplace. What I’d really like is something like a loretone qt66. But before I get anything else for tumbling, I’m trying to find a cabbing set up. I’ve had two slip through my fingers on market place that would’ve worked with my budget. Eventually I’ll find what I need. |

I’ve had two slip through my fingers on market place that would’ve worked with my budget. Eventually I’ll find what I need. Be really careful with Facebook Marketplace. There are a ton of scammers on there. One of the most popular ways to steal you money is once paid they find some address with your same zip code then send an empty package by UPS to that address so it shows the package was delivered.
Had this happen to me when I ordered some tumbler barrels. They sent the empty package to a Best Buy store with the same zip code.
Facebook "buyer protection" is a complete joke. All they do is to keep telling you to contact the seller even when you explain to them that they are a scammer and not responding to messages. Luckily, my bank investigated and reversed the charges.
Have seen a lot of other complaints from people on the lapidary equipment boards who never received the item because they never had the product. They simply steal the photos of other people's equipment and post it as their equipment for sale.
Due to all the scams on Facebook, one lapidary equipment board has tightened up their rules and now requires you post a photo of yourself with the current date. Of course this can be photoshopped, but it is a good start. I also check the person's personal Facebook page to see if they have the listing on their personal Facebook page and that they have been on Facebook for a while, and this was not some new made up account.

That’s a bummer that there’s so many scams out there and you’ve been hit by them. I’ve had good luck with Facebook marketplace, but only because I deal with local sellers. Like the loretone and lot-o I recently bought, I thought it was a pretty good deal. I haven’t done a ton of deals, maybe about a dozen. I’ve also sold some things with good luck. It’s not my ‘go to place’ though for buying things. I agree with you that it’s pretty sketchy. |

It’s not my ‘go to place’ though for buying things. I agree with you that it’s pretty sketchy. Even with local you need to be careful. About a month ago or so I was looking for something and found a local listing. Contacted the seller who said it was still available. When I contacted him about meeting locally to pick it up he did not respond. About an hour later he had deleted his account. Clearly he was a scammer counting on people wanting the item shipped.
I have also heard various stories about people going to meet supposed sellers and getting robbed. These are most often with car ads so the person will be carrying large amounts of cash. If meeting someone in person, best to meet somewhere with a lot of people and preferably lots of security cameras or at a police station parking lot. Legitimate sellers should not have any problem with either of these.
