Thread: Help with lapping of very large hone

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.

slap to sheets onf sand paper on flat surface and lap with running water.I doubt you will have any problems

post some pic of this stone

What about lapping grit on a hard flat surface?

I'm also curious to see pics.

What was such a huge hone used for?

What! 8" x 17"

Thats a bench top not a sharpening stone lol

How about one of the 10" by 4" DMT Lapping plates sideways? lol Maybe you could create a metal rail system on either side of the stone that keeps the DMT plate level all the way across (as you would have 2" either side with that plate) and drop the rails half mm each time until you get it how you want it.





The same method as you would use to flatten ground for paving etc. With paving you sink two pieces of wood or metal into the ground, level it and then drag a third piece of wood or metal across to make it level and remove any excess dirt. (in your case excess stone lol)

If you have some patients, a few spare hours and a workshop you could make a jig to do this. I would make it so its adjustable up and down from all 4 points.

what would a stone that size be used for!?!?
