There's a set screw in the grinding bit. Loosen it with the allen wrench that came with the machine. You should be able to slide the grinder bit off the shaft. Make sure the set screw in the slotting bit is loose. Slide the bit down the shaft to the point where you want to grind a groove in your cab. Tighten the set screw. Put water in the top basin. Slide one of the sponges in the big slot and make sure it's touching your slotting bit. The splash guard provided slips into the square holes in the top. You'll be able to bend the side wings to control spray. You're ready to start cutting grooves, I'd suggest practicing on a slab of scrap material to get the feel of the machine first. Use a fairly light touch to prevent cutting your groove too deep. Good luck. I haven't tried my machine yet either. It's going to be fun.

Thanks, John. Where is the set screw? I think I have the top assembly on right, since I copied the drawing on the cover. Should the water just be poured in from the top?

Don, thanks. I found the set screw and put on the groover. Should the white plastic cap be replaced?
How much water should be in the basin?
Really appreciate the help.

I just wet the sponge and put it in. I dampen it as needed. I wouldn't worry about the white cover but if it will fit on top use it to help keeping water from running down the shaft and into the motor.

I just thought of something. These machines use a DC motor. I'll bet they could be hooked up to a sewing machine foot pedal speed control. This would give full control over the machine.

Don, I can see those wheels in your head spinning with ideas all the way down here!

Don, I would call Gryphon and ask first. It may affect the five year warranty but then again it could be a don't ask/don't tell situation. I know there old band saw had an electronic speed control that cost them about $100 way back when. It was the part that failed the most and was eliminated on the current saw. The motor is DC but has an AC to DC converter built in. I think Ameritool sold a foot pedal switch as an option and it worked on their units as long as you set the unit speed control on full speed.

LOL. Donnie, the day those wheels stop spinning is the day I'll start feeding the worms.
John, you're probably right about the AC/DC converter. It was getting late when I thought that one up, and my brain was already starting to shut down for the night.

Wheels have been spinning again Donnie. I think I'll order a couple of those 360 grit grooving bits from Kingsley. I have a bunch of obsidian cabs, and I'm thinking anything more coarse than 360 may cause major chipping.
Now it's time to go lubricate those cogs in my skull with a nice hot cup of coffee.

Gryphon's groove bits only come in 220 and they are in the glass business. I'm guessing 220 would be fine for obsidian.

Only one Gryphette left and then sale will end. I'll likely replace it with a similar promotion with the Studio Grinder. Or a Tumble Bee and grit kit combo. Or both. Christmas is coming.

Hey John, I got my TWOFER blades. Haven't had a chance to compare them against the blade you supplied with the Gryphette yet. But in a side by side comparison, they are a thinner blade, and at least I feel will be a better fit for 20 & 22 gage wire. They have a very nice finished appearance. Of course they're made in China, but what isn't now a days ? Hopefully I'll get to test the 2 blades in the next couple of days, and will let you know how it goes. I'll run the test on slabs of agate and obsidian to see how they work, and to check for chipping.

Thanks. I'm interested in the results. Gryphon has there grinder heads made in China as are the groove bits I included in the special. According to Gryphon the Chinese grinders are better quality than German made ones they used to sell. I'm sure less expensive as well.
