I know people to charge laps for diamond polish and pre-polish, but has anyone tried it for cutting, i.e. 600# diamond?

Am considering trying it since these "Nubond" laps glaze to fast for my taste.
Just need to get some diamond powder first.

I don't know about laps but I was able to charge brass rod (home-made bur/bit) with diamond and it cut quite well and held a charge impressively. I don't know of any brass laps but perhaps copper would be closest.

I have read bad things about ceramic. Mixed impressions about cast iron. I have not seen any feedback on any of the plastic materials, however.

This is taken from Gearloose's website www.battlap.com:

In recent years, users have found that BATT™ laps can be used for cutting! When charged with 220 or 325 grits, much water needs to be used to remove the swarf quickly generated...It comes off looking like milk. One user called the Coarse charged BATT™ a "Stump grinder". (The BATT™ was originally designed to be a polishing lap, and polishing is the process that used to give users the worst headaches, so these instructions are focussed on polishing.)

I see no reason you can't use 600.  :D

Frank, I'm gonna have to try.
I got a BATT just recently (just as humming suggested) reserved for this. I like the idea of just recharging when needed.

Still looking for diamond powder, though.
Talking with Vanmoppes from Switzerland I think. Very helpful folks. dancer5

Charging the laps with diamonds like this works very well. Can be a bit messy, though.
600 on batt cuts like crazy!

May sound a bit wierd! but in the past we have experimented with all sorts of laps for prepolish. One of the best was a plastic pizza base, the ones with very slight ridges (looks like an old LP)
We used it with silicon carbide grit which settled in the groves and did a good job. Never tried it with diamond but dont see why it would not work.

Urb, really?

For some softer gems I found Vinyl to work quite well actually.
(found some old LPs while hiking actually)

Problematic opals for example can often be given a decent polish that way.
