What are these old shapenning stones for?

Sorry about the misspelled subject but I cannot seem to edit it.





Found the round one in my late dad's stuff, it reminds me a bit of a Lansky Puck but it is enough bigger that I think it would be difficult to use like the puck is used. Two grits, one side is medium/fine and the other is quite fine. It was completely encrusted with dry oil and some mold but I simmered it in an old skillet filled with soapy water and it is clean now.

The rectangular one is pretty coarse and does not seem to have been used with oil. I found it in an old house that I bought.

Round for axes and other looks to be a flattening stone to level stones that have been dished out from use or otherwise need flattening .

The brick looking item is a flattening stone. The round twin grit SiC stone permitted the use for it to be belt driven for sharpening engraving hand held chisels. One could also use it hand held for knives. I've seen that stone mounted in a early sharpening machine at the GRS plant in Emporia, KS. DM

The brick looking item is a rub brick, commenly used in the concrete industry for rubbing down joints and getting a rubbed finish on new concrete walls.

I think the rub brick answer fits the rectangular stone - it is very coarse and not really wide enough to flatten most sharpening stones.

How was the stone mounted when belt driven? That sounds really interesting. I could visualize it flat, but then was it on a turntable?

Yes, it was belt driven, laying on a turn table with side clamps. With the fine or coarse side up. There was also a Norton combination India stone laying beside it of the exact same size and style. Made for the same operations. DM
