Ultrasonic ToolHand held for lapping slabs and geodes, mounted to a table face UP for smaller stuff, say the back of a cab. Velcro granite polishing pads from rough to 3000 grit, just rub the stone over the vibrating pad to get the work done. Dip the cab occasionally to keep it wet. Spray the slab/geode in similar fashion. Just a concept that flashed thru my head. Whattaya think?

just wondering if you tried this? And if so, how did it do?

Might work, if you don't fry yourself in the process. Those motors have open vent holes. Any amount of water getting in could be dangerous.

I would imagine the grit would make it's way to the polished face of the cab and wreck it.

If you just want a polished slab, this might be a cheap way to do it. No ego here. I just wanted to share a thought I had. If it dont work. Well, so be it. Sometimes my mind is spinning with ideas. This one I thought worthy of sharing!

I think it would work, especially on slabs. Those pads can be cut to fit the machine. I cut up the pads when they get half worn out and use them for polishing rings. With the slab laying flat it would be possible to trickle water over it and polish it up. It shouldn't throw water real bad like a circular tool. I am going to try it because I do not have a good way of polishing slabs. The slabs will not end up perfectly flat but my saw cuts so straight and smooth that they will not be far off.
Thanks for the idea. Jim

BTW, I use all kinds of machines around water and have never had even a tickle. If you are careful and pay attention to where the water is going it is not a problem. Jim

Ask Jean. She has a wet lapper but i think it spins instead of vibrates and has a water feed through the shaft and GFCI maximus.

It looks like a neat idea but I second the GFCI. Don't even try without one. They are fairly inexpensive, only cooking rocks is cool.

I think it worth a try. Take safety precautions (of course!) for above concerns.

Harbor Freight has coupons right now for a 4" angle grinder for $9.99. Diamond pads for these are on Ebay for $3--4 each.

Well, rotary action is fast and efficient. It may be necessary for agate and the like. The reciprocating action may wear out as it is often a higher friction mode of motion transfer. And those rotary diamond pads are so cheap and last a long time.

I think the main thing here is that there is not the circular motion which throws a lot of water. With this machine the water would stay put longer so it would require less water. I bought one of these for my son a couple of years ago so I am going to try it tomorrow. Like jamesp mentioned, that motion will wear out quicker and I have proof. My son's machine doesn't work nearly as good now as it did when it was new and it has not had a lot of use. Just hard use. We shall see by golly and I have the perfect slab to try it on.
Stay tuned for highlights. Jim

Ask Jean. She has a wet lapper but i think it spins instead of vibrates and has a water feed through the shaft and GFCI maximus. James, the flat lap has a water drip onto the surface of the lap. (Water from black cup rear center of photo below, then comes out through hole in side of unit into another cup.) The biggest threat the water has is getting into the bearings. I've never worried or even thought about electric shock, since the motor is entirely enclosed in the housing, with no way for the water to get to it. You'd have to submerge the entire machine in water to have a shock problem. No GFCI on it.

My Ameritool flat lap looks just like Jean's flat lap.

My Ameritool flat lap looks just like Jean's flat lap. Are they difficult to use? im pretty mechanically inclined.

bwinslowI'm not mechanically inclined. Yes, it is easy to use. I don't have any trouble. Should add that I don't do spheres on it. I do the back of cabs and it is a help in roughing out something to carve.
