Well I may or may not have asked the seller to hold it for me. 🤭
Is this a good entry level rock machine? I know so little.

NDK refurbished one for me recently. My research showed it was a great unit for small spaces. You will need to attach a water supply. This one looks to be in great condition. Please post photos when you pick it up. Here is mine showing the water system:

Well I may or may not have asked the seller to hold it for me. 🤭 Is this a good entry level rock machine? I know so little. That one looks like it is in excellent condition. It is a great piece of equipment. I bought mine in rough shape for $50 eight years ago and did a full refurb. I never used it fully for cabs as it was intended but every cab I have ever made has been started with that machine. Mine is equipped with the trim saw, 80 grit hard diamond wheel and 220 hard diamond wheel. That makes it the perfect cab preform machine. Trim out your shape on the saw and do all the hard grinding of the dome there and then move over to another machine with soft diamond wheels to do the finishing steps. I also do a ton of prep on my tumbled rocks with it. Again the trim saw and 80 grit diamond wheel are perfect for that. If you are planning to use it as a stand alone cab maker I would recommend replacing the silicone carbide wheel with an 80 grit hard wheel. On the expando wheel you can get normal sanding belts in varying grits or you could spend a little more and buy diamond coated belts. There is also a thread on the end of the shaft. A 5.5" diameter polish head can be mounted there. You can get canvas, leather or diamond for that. This was my refurb from 8 years ago when it still had the original wheels mounted. forum.rocktumblinghobby.com/thread/54828/Chuck |

It has found a good home. This will be fun. Also he has 700 lbs of Montana Moss rough, and some of those rocks found their way into my already fully loaded minivan.
Daughter is beyond enthused.

Ordered 3 of the cheap Kingsley diamond blades, an 80 grit diamond wheel, 400, 800, and 1000 grit expando belts, and a 1/4” felt polishing pad. The sc wheel is quite worn on this one.

Did you get SC belts or Diamond? You''re going to need something between your 80 and the 400. SC wheels are very messy and need to be dressed, diamond is the way to go. |

I got a diamond hard wheel but just SC belts. Maybe should get a 220 diamond belt yet? |

Wait and see what other advice you get here before you shell out for a diamond belt. You may be just as well off with the SC at that mesh level. I'm out town and can't remember how I set mine up, but I'm pretty sure I used 100 then 200 SC belts prior to my first Diamond belt which I think was a 220 or a 325 maybe. If you get any diamond belts remember you'll need a dressing stick too.
Does your expando wheel allow you for a quick belt change? If you have the stock wheel that comes with the machines new you'll definitely want to switch to something that does not need to be removed each time you want to change the belt.
I have the same combo unit and started with SC belts then quickly moved into Diamond belts but wasn't satisfied with the whole idea of belts and got a CK6 about the same time. The combo unit turned out to be a big money-suck IMHO but I tend to learn best from my own experiences. You may fare better by taking good advice from this forum and jump into a 6-wheel sooner by saving your expenses with the combo unit. If I had to go back or give advice I'd probably say stick with the SC and save up for a different machine, of course that depends on your long term goals and budget.
One thing you need to learn is that different mesh sizes of different materials can't necessarily be compared apples to apples, for example a 220 SC belt doesn't necessarily equal a 220 diamond belt or a 220 diamond wheel & etc, etc.
Anyway you look at it the machine was a good purchase! I love my little saw except hated cutting with oil and switched to water with an additive. The combo unit is difficult to drain but you'll get used to that, get some big door wedges and prop it up when you're cleaning up (NEVER run with wedges under machine, it can walk right into your lap!)

Good advice like this ^ is hard to find at any price, and I just got it for Free. I’m trying to keep this a hobby at this point, see how the daughter grows into it. Thanks for the input, julieooly, (even after I desecrated my wife’s sewing mat)  |

Nate added a water drain under the saw for me. It should work well.  |

Use the sic belts until you convince yourself you need diamond. But . . . wash your stones between grit stages. You don't want to carry grit up the scales. If this were to be your only machine, I'd save my diamond belt purchase for 3000 and above.
Just another perspective but I run oil in my trim saw except of special occasions. I hate cleaning and draining the saw so with oil I do it once every 3 months and not daily as I would have to do with water. Even rust inhibitors, don't prevent rust. Soap, oil-dri, and good shop technique overcomes every liability of oil for me.

The gentleman that sold me this saw is now a member here. It is tedw, welcome to the forum, Ted! I can remove this post if you didn’t wish to be introduced. In the coming months he is planning to list some other lapidary equipment, a large slab saw, a UV10 with extra bowl, an oscillating lap. All in mint condition. Was a pleasure to buy from him, a great seller. |

My sc belts are 400/800/1000. What other grits do I need between 1000 and the polish wheel?

How do people find all these sweet deals on equipment. I know I don't live in the best part of the country for the hobby, but I rarely if ever see anything near me being sold for anything resembling a reasonable price. Any advice on where to look for deals?
