Thread: Best thing for hone lapping

While it is probably as accurate as can be had I still like my GDLP or DMTC in the kitchen sink with water trickling down to take away the swarf. Flat enough for government work.

A good flat granite block can be expensive.

They are quite proud of these you are right. I could not afford one, I have access to it in my building. I just lay sandpaper down, wet it, and lap away.

You're right JimmyHAD! I usually use a granite piece that I found at the back of a granite cutting place. I did an experiment and tested the dumpster piece and went and lapped again on the Starret slab and didn't find much of a noticeable difference. All of the pencil marks went away very quickly as if it was flat with only a couple of tiny marks on the two ends that disappeared with the next quick lap.

It is way overboard to use this. Just a little test to calibrate my own granite slab.
