Thread: Help with lapping of very large hone

Hi anyone has exprienced lapping of large hone (8x17"). I was given an old hone by my aunt who had it from her father who was involved in national stone mining business. It looks slate ish however I could be surprised due to background of the original owner. I do not want to just experiment with this hone. I do have stone plate large enough to accommodate sanding belts from floor sander however they do not come in higher grits. Anybody can chip in. Many thanks.

How much lapping does it need? I've no experience with lapping huge stones, but I can tell you that the bulk of your work needn't involve higher grits. Once you get it flat enough with the lower grits, I'd probably just set the hone on a counter and polish the top with sheets of wet/dry sandpaper taped to your stone plate.

Take it to a place that does marble & granite counter tops. They have the equipment and know-how to turn granite and marble to shiny glass

Only trouble is that on this side of pond the price is a bit steep and also this hone is the only one with the history and I would prefere to stay in low speed.

This is what I thought of just was not sure about edges of those papers damaging the work.
