I use the same machine for grinding turquoise, malachite, lapis, and roughing stones for tumbling. Harbor Freight has the same machine for a few dollars less. The 8" wet wheel is very agressive on the copper mineral stones. It works very well to flatten a cabachon. The smaller 6" wheel does a great job on shaping cabachons. You will need a cup of water to cool the stone. I like it.

For doing cabachons and shapes, it is not the best. It will work however. For tumbling you cannot go wrong. Do not add anything to the water side. It foams up and runs all over. I use it without the shields. For serious cabachons the Loretone combination unit is great. Another point, never mix elements. Once you use stone, never again grind metal unless you reface the stone wheel.

I had to take the page off the pagehttp to get the site. Yes, that is the unit. I like 6" as everything is cheaper. Most folks like the 8" for control of the work. For water feed, mount a 5 gallon bucket above the machine with a thruhull fitting on the bottom. The gravity will make the drip through the petcocks supplied. That one is my favourite. I do have a unit like the one shown in the previous comment I might like to sell. I would let it go for 50$ plus shipping. It does come in handy. It is not lapidary material however. With the loretone, once you have reduced the corundum wheels to zero, replace with diamond. Much much better.

Many folks have spent countless hours teaching me. It is a little thing to spend time with another person. The unit has an angled mount with four machine screws on the back. It needs a mount for the motor. If you can get the motor and mount for the price you indicated, have at it. There are holes on the top. Mine came with petcocks but time has passed and yours might not. If not, get some petcocks to fit the holes. The tubing you will have to supply. I matched the petcock diameter with the fitting on the bucket. I also use 1 1/2" wheels. I have a diamond 100 grit mounted on the first stage, and an expanding rubber drum on the second. I change belts for the different grits. I also put a leather belt for polishing. It comes with a leather pad and threaded plate for the end wheels, and they are all tied in with that. I replaced the disc with a nut. The rubber drum does the fine work. I have also found out, the saw needs Cool Tool. The bearings are lubricated with the saw water/oil. This is important. Cool Tool is inexpensive and a lot goes a long way. You will also need dop wax and dops. Metal dops work the best but wood dowels suffice. A shape template is a plus, and an aluminum pen for marking the shapes.

You need corundum wheels, carbide ones are a pain in the neck. By the time you go through the ones that come with the machine, you will be ready for diamond. The diamond wheels are twice the cost of corundum but last ten times longer. You will have learned the touch by then.

You kinda lost me there, I went up to the site you posted and they no longer show the unit. I typed ba64 on search and it came up blank. If you are going to scratch build, why not just get an arbor and do it up? When I first started this, I used the unit you first showed with good results. By chance I ended up with the loretone combination unit. I had put my rubber drum on a grinding machine I got from Home Depot for 45$ and ran it dry. If you get the combination unit, you will only have room for two wheels. On mine, I run a 1 1/2 100 grit diamod and a rubber drum. I have found the disc just gets in the way and sometimes picks up grit. The trim saw is nice but it is annoying when all I am doing is cabbing. The biggest factor is speed. The final shaft must run at 1750 rpm. You can go 1-1 with the motor and arbor if you use ceiling fan rheostats of 600W. I prefer to reduce the motor speed at the shaft by going 1-1 1/2. Any internet lapidary source can provide the corundum wheels, and any hardware store can provide arbors. It is easier than most folks make it out to be. All I do is grind stones and polish them.

That works. If cost is an issue, as it is for most of us, you might consider a two station arbor. That would cost about 25$. The page you showed had drip wells for individual wheels. All the unit is, is an arbor with drip wells. The further from the main bearing point the more vibration is present. If it were me, I would get an old bedframe, an arbor, a motor from an appliance repair place, a piece of handi wood from Home Depot, and drill away. The bedframe I would cut to size. What size? Two feet by 18" would be over kill. The steel in the bedframe makes a great corner angle, and it can be used to fit the arbor. So you would have pieces of plywood, steel frame, machine screws, an arbor, drip pans, tool rest, and motor mount. A standard 36 grit is great for roughing in, 60 grit is great for taking off the coarse marks. Sanding belts do the rest. A leather buff does the polish. Before we had the lapidary giants over the internet, with their fancy paint, and great packaging, We little folks with a vision, made their own. Remember, all you are looking at is some bent sheet metal, stamped bearings, and a name. Skip the name, make it out of steel, and create some pieces of art. If you can see it, you can make it.

docone31 when you said "don't add anything to the water side it will foam up " do you mean don't even put water in it or add things to the water

I was referring to soaps, oils, etc. It just foams and foams and foams and foams. Goes everywhere and takes a couple of tanks to clean it out. Water is good.
