Stones for cylinder hone?

Post by SteveM » Sat Oct 06, 2018 11:59 am

I have a box of 31 of these stones in metal clips. Not sure what they are for.

The are 6" long and 1/2" square.

Can anyone ID them?

Does anyone need them?

Those MAY be for a Sunnun 'AN" series engine cylinder hone. Been a long time and I don't remember how the stones attached to one.

These appear to be BAY STATE stones. As new they are sharp cornered. As example ; BAY STATE C120 .16.V32 #10 .
This identity is ink stamped on the side of the stone but that goes away'.

These are brand new, but there are no markings on them. Seem that you would want to mark them.

My search of Bay State got me to Radiac Abrasives which absorbed Bay State. They have stones similar and they are dressing sticks. I still think there was a hone unit for the ones we have. In pic # 1 there are marking of a foot clamp which are similar to a smaller hone. Some of the Sunnen stones are similar with a metal back "clip". These attach differently but same application, i think. The Sunnen' s stones are marked Blue Point.
