Thread: I Found It Over There

Actually if you could run the spray on a foot pedal it would be great. Both hands on your work and it would only have to run at the times needed.

The other option would be a knee operated tap. Provided you have good water pressure the tap could just be a bolt on to the saw.

Just finished up this big beastly 3"x 7 3/4" for Gonzo....hadn't had much time lately but trying to knock out a few more hones. Still a Tad low in 3 corners but wont effect it....bout to give it a test run and see how it works....pics are of lapping with 320 dmt plate.

Material is from same area my last 12k+ stone I made came from.

This was a cool thread to read through!! I have friend who is a machinist that makes these saws: Walk-behind and Hand-held Concrete Saws Manufactured by CS Unitec

Not sure where they are getting the blades from, I wonder if they can make a chop saw or table saw version of this?

I did see a new chop saw that slices thru 4" heavy angle like butter with no heat, special blades. Wonder how they would do with rock?

Any chert is a potential hone. That's a saying that an engraver told me. there's a huge difference between finding something you can use as a final finisher vs. something you could sell in volume.

The thread somewhere below here (or above here) showing pictures of honing on various natural stones shows how well some of the jaspers finish a razor, but good luck finding large finished pieces with no surface imperfections cut and thicknessed like a hone. I don't have trouble finding cheap large slabs with no surface imperfections, but they are not shaped like hones - they are 1/4" thick slabs cut for jewelers. A big 10 pound piece of the stuff is a basket of fun nobody would want, because it approaches the price of a real hone and none of us have a practical way to cut it into a hone. The in-between (thicker pieces that are narrower and rectangular) don't really exist because we are not the market for the jasper.

Like vasilis said early on, the stuff that is boring looking is best.

I had a zulu hone. My particular example was not up to the standard of finishing a razor that either of my pieces of owhyee jasper are. Neither are most stones, though. It's not hard to find things that make nice finishing hones, and for cheap, but to get them in a 2x8 or 3x8 geometrically nice stone and get 1000 of them is entirely different.

For me it is the one time good luck piece of stone I'm looking for, getting vollume would be interrested if you try to set up a business, and if you find something like that there is not that much market for fine finishing hones (beside us nutjobs here using a straight razor). but it would be realy cool to shave with a blade sharpened on a piece of rock you found yourself somewhere in nature.

Dennis, that hone looks realy nice! when you start selling them I'd like a PM so I can get in line

I just hot a bunch of rock from my usual place. About a third of it was full of tiny little factor lines. It is not good for hones. It will make some decent garden rock. There is a lot of grading that takes place as well. Not every slab that gets cut gets to be a hone. Between crack and inclusions it brings the numbers down pretty fast.

Amen, and it sadly takes tons of work before you can tell if its good for hones even...then nearly finished before all the micro fractures show themselves

Made a stop and grabbed some rocks yesterday on the way home from a cut out in the roadside...a blueish green stone, loose stuff around it but has some bigger layers in there.

Now there is a likely spot to do some sampling and chipping.
