[Rockhounds] Suggestions on harsh grit 'galaxy' style diamond wheel for genie?

[Tim Fisher]

Get a reputable brand textured wheel. I use a UKAM "waffle" textured wheel,
80 grit but 60 is even faster. Be aware that they can cause major chipping
but they are incredibly fast. If you want to spend some serious cash or hunt
around for a used one the Hi Tech All in One rotary lap is perfect for what
you want to do. I passed up an old Covington rotary years ago before I
realized that it would have saved me hundreds of hours getting saw marks off
small pieces over the years. Plus you can get cheap toppers and throw them
away as they wear.

Subject: [Rockhounds] Suggestions on harsh grit 'galaxy' style diamond wheel
for genie?

 So I need to grind down some quartz, basically I have some 1.5 inch chunks
of amethyst that are not flat enough on the back for what I need. Tried the
flat lap but we only have a faceting one and the wheels are too delicate and
expensive to want to slam through quartz with. So I am using my genie and it
works fine since I don't need perfect flatness, just kind of flat, so I just
need to knock down high places to get it to about 1/8 inch of flat, but I
want to do a lot of these so I'd like to get a 'galaxy' style hard harsh
diamond wheel to put on in place of the genie 80 grit so I can slam through
a lot of quartz quickly. These stones are just going to be glued down later
so the grind being very course is just fine. I would like to find maybe a 40
grit or 60 grit wheel I can put on my genie, not sure if I should get that
from Diamond Pacific or some third party vendor. Suggestions? Some years
ago, last I was dealing with diamond pacific wheels, the quality seemed to
have dropped a l  ot and some of the direct from China vendors were coming
up with ok product at a much lower price, not sure if that is still the
case. Worst case scenario, I could also just get a new 80 grit, my current
one is sort of midlife right now.  But I'd really rather get as course a
grit as feasible since removing quartz material quickly is the main goal for
this project which will probably be an ongoing business venture.-Eva
