OK I got a Gryphette grinder with a Glastar grooving blade.
How long will this tiny blade last? Says 200 grit diamond.
Do you make several passes around your cab or just one cut?
Don't want to waste a bunch of cabs figuring this out.
Bit instructions say 16 and 18 wire gauge channel. What size wire is everyone using?
Thanks for any help or hints

Jeff I have the Gryphette, my first blade lasted several months and grooved maybe 40 cabs, it depends on the material, I think it was 100 grit though. 200 is much softer. I now have a 60 grit to try. We use 20 g square or 20 gauge half round with the round inside. Look in the wire wrapping for old posts by me or Tonyterner and you will see them. The harder the stone the more you will wear it out, the biggest struggle for us is trying to get it even depth the whole way around, Tony is working on some type of stopper to attach. It is trial and error, just don't try it on thin girdle cabs or with too soft material, or they may crack! Hope this helps, and doesn't further confuse you!

I have some of these bits tinyurl.com/mkg59zI have about 20 grooves in mostly agate with hardly any wear showing. I cut the groove a little shallower than the wire thickness, and use 20 gauge or 2 - 24 gauge twisted together. Both round wire.

Thank you both for the input. I went back and looked and read all you both have done with the groover. The machine grooves to perfection, my wire wrapping needs work now.
First attempt looked like a granny knot squished with pliers. Second is better but no where close to the tight wraps you all are doing. I'm using craft wire from wally world.
thanks again JEFFD

Hey I did up some photos of how I do the bail wrap for someone else. Maybe this will help. Mine aren't perfect but they are not bad. Now through the magic of copy / paste....................... 1- Take a 3" chunk of 20 gauge craft wire and while holding your twisted wire together hold down the new wire with a finger on the back side of the cab. This needs to be done with one hand. 2- Start twisting the wire around the bail. 3- Keep twisting, don't worry if its not tight to the cab. 4- Once you have twisted to the loop in the bail, use the piece you were holding to the back of the cab to twist around until it is tight to the cab. Both ends should be to the back. 5- Trim the ends off and push down.

What a great hint, Sasrock! I am forever getting loose bails. I've got to give this a try! Good on you. T

THANK YOU!!! Looking at something someone has done and trying to duplicate it without knowing how they got there was making me crazy.
You still make it look easier than it realy is.
thanks again JEFFD
