I have a 30" cast iron flat lap. It's currently stored with wheel un mounted so a photo would take some time.

If the guts of the machine are solid- 1/1/4 inch shaft, heavy steel frame, keyway in the shaft, 1.5 HP motor,double pulley, it is a good thing to get. You can have a machine shop turn you a bridge abuttment drop, usually about 30" by 1.5 inch or thicker for a very nice price. That machine will last you a lifetime. It can be either slurry or diamond. I run mine both ways.

The key is whether the surface is flat. We used to send ours back to the machine shop when it went more than .04 out of true from the edge to the post. ( I have at least ten spare heads)

The good machines are really rather rare but they are out there. New ones are really under engineered. John Nickerson has fabulous drawings of how to build one in "the hot glass information exchange- 1978 . An idiot can build it from Nick's drawings. If this one meets my standards, save time and money and buy it.

What would a refurbished machine like that fetch for price? I have two with cast iron frames- probably 1930-40, newer slow 3 Hp motors 400V three phase
Dims the lights in the building when you start one, 3” plus thick wheels
But in Sweden , Anders

I think about three thousand dollars, perhaps more. It would have to be going to someone who knew what they were getting. They build some pretty cheap ones here that won't do serious work. If they cam ere, the motors would have to be switched out. I assume yours are 50Hz. They sound like they're right up my alley.

That might make it worth shipping if I decide to sell them

Shipping on ships is strange, its by volume. 10 cu ft of styrofoam is the same as same amount of lead

A three inch thick wheel implies that it's more likely a newcastle stone set up. Are the wheelheads tapered at all?

Well, in the land of containers, They are either less than truckload or truckload. If you receive a container in Norfolk, it had better be DOT ready or no trucking company can move it onto the roadway. That means a 44 thousand pound or less container. We looked at .04 cents a lb to bring product to the US from Shanghai. Then it went drayage freight or railhead but both ways it went in a container. Eventually someone weighs it. Sooner is a lot better.
