Thanked: 2Thats what I was thinking, something else to do that keeps me out of trouble that I can have fun with.
I cut the small black stone and am lapping it as we speak. It is very hard and produces a very fine gray slurry. This will be interesting.

Thanked: 4830I have a procedure for lapping that has me lapping under water. In time I will build something to make it go faster but for now it is all hand lapping. I put the pug in the sink and then a thick piece of umber mat and the the dmt and rub the rock against the dmt while it is under water. If it works out that your sink is at a good height the ergonomics are not bad. In an attempt to find rocks that are not crazy hard I often hit the rocks with a 5lb hammer to check them. I think at this point that mid range and a bevel setter would be my holy grail. I have some recent coarse rock that I have not had the chance to refine, but I am always hopeful.

Thanked: 246I usually look for sedimentary rocks or rocks that fracture conchoidally then do some quick preliminary tests with a piece of old file to see if it cuts hard steel, also use the hammer test like Shaun. Here are some of my more recent stones:

Thanked: 4830I think the rocks that conchiodally fracture make them novaculites, which is a large group that includes the arkies. All the rocks I play with are from the metamorphic family. One of my bad habits is getting too many rocks ahead of myself and then I can't remember which rock came from where.

My father passed on some stones he had collected to me and my wife. She made notes etc. to put in the box's. The shelf they were on collapsed under the weight and all the notes got mixed up......
