I've had some luck by taking the wheels off and reversing them. I've heard some talk against doing this, but it worked for me until I could afford new wheels.

How bout a little Zeplin ?
Or if you're old enough to remember him, Stan Freberg.

Dang Phil. Last time I looked for flange washers, they were all over ebay. Can't find anything tonight. You might look for precision ground flat washers.

Pat, I live on a gravel road. I just dry the oil off of my slabs and lay them on the porch. By the end of the day they have a coating of fine dust on them, and any cracks stand out like a sore thumb. I'm sure that if you just dried the outside of your slabs and dusted them with flour or something else, there would be enough water left in the cracks to make them stand out.

Shermlock's last log in was Oct.26th. of last year. If anyone knows him, have him respond to this thread.

If the slab was cut in oil, dust a little bit of talcum or flour over it. Any oil left in cracks or voids will be drawn to the surface and leave a wet line in the dust.

Looks like pet wood from the rind in the first pic. Probably a common opal replacement from the waxy look.

There should be many good machinists in Israel. Some should be familiar with the American inch measurements as your Israeli military has some American made weapons systems.
If you could become friends with someone in the American Navy, Our ships visit Israel quite often. Perhaps you could get someone to bring you a machine onboard their ship. I don't know if you'd have to pay import taxes, but at least it would save shipping costs.
I think we do have at least one other member from Israel. Perhaps one of our members will remember the name.
Wish I could get back over there. I'd love to score a couple nice pieces of Eilat stone.

Heapsy, the only links I could give you for shaft material are U.S. links. You'd have to pay shipping and import taxes on everything. It would probably be much less expensive to find a machinist in your own country to make the shaft for you.
Yes, a machinist would have to do the threading for you. You're probably on the metric system, so as long as the shaft is 1 inch to fit the wheels, it wouldn't hurt anything if the threads & nuts were a metric size as near to 1 inch as possible. If you drill & tap the shaft for a spin on disc, that will have to be 1/4 - 20 thread.
The 6 inch Galaxy & Nova wheels are 1-1/2 inches wide.
Lortone's shafts are 3/4 inch, so you'd have to buy adapters for all of your wheels.
If you don't mind me asking, which country are you from ? We may have a member living near you who can help.

Heapsy, first, welcome aboard. You'll find lots of helpful people & information here. Ask all of the questions that you want. Someone will be able to help.
Before starting to build a machine, first ask yourself how much room do you have for a machine. Once you've answered that, there are a few things you should know.
#1 -- The shaft should be either stainless steel, or cold rolled steel. It should be long enough to allow at least 1-1/2" between wheels. The wheels on most commercial built machines are too close together.
#2 -- The left end of the shaft should be threaded with a left hand thread and have a left hand nut. The right end should be threaded with right hand threads, and have a right hand nut. You'll only need about an inch of threads on each end.
#3 -- If you want to use an end plate for buffing, most end plates come with a 1/4" 20 thread screw attached to them. You'll need to have the right end of the shaft bored & threaded 1/4" 20 thread. This is best done by a machinist in a metal lathe.
#4 -- For bearings, you'll want sealed pillow bearings of the proper size to fit your shaft.
#5 -- You'll want a motor of at least 1/3 HP, which should turn 1725 RPM's, or as near to that as you can find in your country.
#6 -- Pulleys should be the same size for both the shaft & motor. I'd go with 2-1//2" pulleys. The center hole in one pulley will have to be the same size as your shaft. The other should fit the motor shaft. Both pulleys should have at least one set screw to lock them in place on their shafts. Take one of the pulleys to an auto parts store. They can fit the proper size belt to it. You'll have to decide on how far behind your machine you want to mount your motor, and get a belt of the right length.
#7 -- You'll have to build a water tight base pan for your machine with at least a 1" lip all around it, and a drain fitted to allow water to run from the pan into a catch bucket. And you'll have to build spray hoods to fit over the wheels.
#8 -- You'll have to devise some sort of water supply to each wheel. I'd use separate valves for each wheel.
There are many other things to consider, but these should at least let you start designing your machine. As you start your build, take lots of pictures and post them here. We'll be able to make suggestions and help you.
And again, ask lots of questions.

Dang Mel, I thought Texas was an open carry state. blogs.wsj.com/numbers/map-where-is-open-carry-legal-1715/While I have a concealed carry permit, I seldom carry concealed. If I feel the need to carry, I strap it on in plain site. I only got my license because my wife was being followed by some creep when she left work. One time parking beside her car, and meeting her when she came out to her car with my gun in plain site was all it took to convince the guy to find someone else to stalk. (I suppose that the evil grin I gave him didn't hurt either).

Not quite the same, but this is from an abandoned quarry N.E. of Riverside, Ca.

Don't know what the laws are in your area, but I'd get a concealed carry permit, and a big gun to carry. Next time the guy tries to follow you, stop dead in the street and step out of your car with the gun in your hand. Most people who are trying to scare someone won't be expecting to be confronted. He'll probably need to change his drawers & wash his car seat.

You have a very nice little specimen of horn coral. That is the way a nice piece is supposed to look. A few million years back when these corals were alive, the pointed end would have been attached to a rock with a strong muscle sort of attachment. The larger flower looking end would have had tentacles coming out of it to capture small bits of food.
Millions of years ago most of Ohio was an inland sea. Ohio is rich in marine fossils.

Better check & make sure that Shar Pei hasn't made any indelible marks on your carpet.
