Paul, cutting and slabbing is what us guys that don't really know how to knapp do. You are a great knapper so why mess.  Justin

I've used one "sawed" preform.  Thinest blade I've made, but that was because it was cut thin.   :-[  It was kind of hard getting it started because all the edges were right angles.  I'll try and post pictures soon. 

Nice points Dick.

Nice points Dick and some pretty rock, made 3 obsidian preforms yesterday out of some of Justins rock I grabbed from Pappy's
I have to say I waste a lot of rock would love to be able to slab some. Dick thanks I would love to try some coral and I'm sure I can find something to gift you as well ;)

Well guys I also have an 8" wet ceramic saw. I think I will try and cut some coral today, or at least see what happens. Eddie, do you think oil or water is better?

For hard rock oil is supposed to be better.  Oil also keeps it from building up deposits on the diamond edge.  Justin

  Dick, you need oil. I cut my rock with a 10" wet saw and it still won't cut Coral or hard jasper that Brian Melton sends me.

the key to cutting coral is the blade thinkness (kerf) and your blade speed.depending on your blade you would have to change pulleys. I buy my blades from Daniel Lopacki  http://lopacki.com/tips/  I use only water and dish soap because the oil will soak into the coral when I cook it.You cant cook a head of coral you will have to spall down to what you want to cook.

yeah I tried it on some but it was too much work and didnt get all the oil out. Water and soap works fine with my saws and I have friends who use the same.
