What's that first rock? Where did you get it? It looks like some rocks that I find in Lake Superior, but I don't know what they are. It doesn't look like Mary Ellen to me. It seems to have hematite or something similar in a layer near the top.

The start capacitor is there to provide a bit of stored power as a boost to turn motors that already have a load attached to them, some fans and pumps for instance. A saw shouldn't ever have to start under load, and once it's running the cap isn't really necessary. A run cap is there to smooth out the minor changes to the incoming power supplied to your machine, sort of like a shock absorber for when your neighbor turns all his Christmas extravaganza contest lights on all at once. The run cap soaks up a bit of power when the line is up in power and releases it when the power drops a bit to smooth out the average supply. It can also help keep a heavily loaded motor running. That's an excellent explanation. Thank you. By the way, I'm the neighbor you described.

If you are willing to buy the cheaper 1/4 horse motor, why the need for a 1/3 Dayton. I have an 8" and 10" saws and neither has a capacitor and I've never had a start problem. Look at the service factor too, 1/4 has a 1.15 and the Dayton has a 1.35, as does the 3K771 1/4 horse Dayton {$20 cheaper than the 1/3}, higher service factor translates to more robust windings. Good point, I'll check that one out. The old motor was 1/4 hp.

The old motor didn't have the correct frame, although I did keep it. It had been cut to make the slots big enough to fit on this saw. I have bought used motors before, but they're not very easy to find where I live. I'm in a small town with nothing bigger within a two hour drive. I'm all for buying a good used motor, but I think it might be simpler to just buy one new.

The Dayton has a start capacitor only. The other has a start & run capacitor. You can easily run a 10" blade on a 1/4 or 1/3 HP motor. HP tends to overdo their motor sizes for whatever reason. What advantage is there to a run capacitor? Would it be good to have on this saw?

A couple weeks ago, I posted a question about wiring a motor to replace one that I burned up on my Lortone ST-10. I finally got around to getting that one wired and now it's not working right. I had second thoughts about using it because it's not thermally protected anyway. So now I have to buy a motor. The owner's manual for the saw says to use a1725 rpm, 1/4 hp motor with a Nema 48 frame. I was talking to holajonathan about motors and he pointed out that the newer HP clone of the saw uses a 1/2 hp motor. I have found two motors that might work for me. 1. Teco 3500 rpm motor with two capacitorsThis one has two capacitors. I'm not sure why that might be better. It's also too fast, so I'd have to slow it down by using different pulleys. It's $100 including shipping, plus the cost of at least one pulley. 2. Dayton 1725 rpm motor with one capacitorThis one only has one capacitor, but is the right speed and is 1/3 hp. It's $150 with free shipping. Buying a cheaper item is always a plus, but the price difference isn't that much by the time I get new pulley, so I'd rather focus on just getting the best motor for the job. So which one would you buy? Thanks!

Looks good, Chuck. I have a piece of cladoproa in the saw right now.

I did a positive review of this machine, calling it my favorite tumbler. I just made a new thumbnail with the word "favorite" crossed out. I also changed the title and description to reflect my current feelings about it. It's a sad day.

This is a great post. Thanks for taking the time to document your problem and solution. I have two Lot-Os with Fasco motors now and so far they're both running well. One Lot-O is fairly new and the other one's motor died after about ten years of use, so I bought a new motor. I sure can't complain about a motor dying after ten years, but four months is another story.
Do you know if the new motor you bought from the Rock Shed is what is currently being shipped with a new Lot-O or is that just a replacement that Shawn is selling?

Two uses in one picture. 1. Build a zoo behind your city to hold all your zebra jasper 2. Build a train for your zebra jasper to ride in. That's a pretty niche use case. I like it though!

Jugglerguy I missed this thread originally. Have you already made the video? I haven’t checked YT in a while. You already said dish on coffee table and this is similar but a little different. We have a lazy Susan on our dining room table. We often have it covered with a pile of polished tumbles. It is especially great if you are having company over and will be serving coffee or even a meal. People will sit at the table for hours talking and telling stories while perusing all the rocks. I think it makes the visit last longer, so…. This could be good or bad depending on who you invite!🤓 I haven't made the video yet. I'm still gathering supplies. One of these days I might get around to it!

I was watching the Charlie Brown Halloween special and while every other kid got candy, Charlie Brown got rocks. It crossed my mind to maybe give out some to trick or treaters but then again, I had this sort of funny thought I might see them again later that night getting thrown through my window. My kids are young so I see the opportunity to disperse some through their teachers as little prizes. It is the age old question though, what to do with them. But I think what we ultimately all love is not the end product so much, but finding or buying that rough and watching the evolution of the process. Just like doing ceramics, it's not about having a house full of ceramic pieces, but throwing the lump on the wheel and seeing what you can make out of it. I agree that this is much more about the process than the finished product for me. I just get this question all the time so I thought I'd make a video to answer it. I actually made a video showing what I do with my tumbled rocks, but since most of them are just stored in boxes in the basement, it wasn't a very good response.

I have done a few shorts and I plan to do more. Other than one of them, I think I put just as much time into making a short as I do other videos. I think I might be doing it wrong! I looked at a few of your videos. I really enjoyed the shop tour.

Welcome from AZ. I have YouTube videos too, you're better off looking at Rob's... We’ll need a link.

Welcome from Central California! Michigan Rocks needs a recruitment award! Some people who comment on my videos seem to think I figured out how to do everything myself. The truth is that I learned almost everything here. So I like to give credit where credit is due. Recruitment is just a byproduct of that.

I’m glad you arrived here so you can get some better information than that Michigan Rocks guy can give you!

Thanks everyone. I might need to get a longer belt to make it looser. There's no way to make the motor closer to the shaft and the belt was pretty tight. Thanks for that tip, hummingbirdstones.
