The two picture jaspers and the moss agate are from my batch of tumbled cabs and the tan/brown one is a quick cab from one of Jugglerguy's Lake Superior trips.    groove wrap money shot. You may notice the groove looks better after being tumnbled. It softens the groove.    Thanks for looking Chuck |

How have you found that stuff to work with, Chuck? You mentioned that the first one chipped a little or something. I slabbed a larger rock and it was fractured all over the place. I dropped the slabs from about two inches and they broke into several pieces. Other rocks seem more solid. That one looks great.

I tried two before this one that had better patterns but one broke at the trim saw and the other chipped out on the groove cutter. So thats a 1/3 success rate. Not enough to stop me  Chuck |

Not an ideal material either. The ones that turned out are pretty cool though.

I haven't dismissed it, just wish it was a bit better. I does tumble nicely.

They keep looking betterer and betterer!
Let me ask you, now that you have done quite a few of the grooves, do you kinda have an eye for the right depth or is there a mark on the grinder wheel for the right depth? I put a mark with sharpie on mine, but it isn't a real thin line so it really isn't much help. I know you used to use a wire for a gauge marker. I am just wondering if you are beyond that now.

Thanks Tela. Yeah I think in the last year I have cut well over 100 of these. The smart thing to do is using the sacrificial piece of copper while cutting the groove but I get cocky and skip that step pretty often now which results in having to go to the basement to deepen the cut sometimes when I am upstairs in the middle of a wrapping session. That can throw you off your Groove (pun intended). Chuck |
