I jump from 200 to 400 but there is no way I can jump from 600 to 2000. It would take a very long time to 600 smoothed down with a 2000 grit. Not impossible, just way more time than I would want to spend.
I use an 800, 1000 and 1500 in between. Jim

add the extra steps in there working your way up to 2000 and then go to cerium, if you can see scratches when you go to polish then one of your steps is not doing the job.
you need good light just over head where you can rotate the stone after each stage looking for scratches that stand out. Each stage should look uniform with no scratches jumping out at you as you look at the stone dry.

So silicon carbide expando belts stop at 600, where can I get the belts in between and whats the grit rating I need? Trying to avoid expensive diamond belts if possible, my arbors use the 8x3 belts n they r expensive. Do I need all those grits to do only the quartz or does all those wonderful jaspers n agates I got from yall need them too?

The scratches may be from a lower grit, and it's possible you may need to go back a few stages. Make note of which direction the scratches are, and go across them. This will make it easier to see if you're removing them. Having the cab completely dry while using the light as Diane advised will show you the scratches the best. I've gone from 600 grit SiC to polish, so it's not impossible with your set up. The worn 600 is a good step, I had one so worn it was like a prepolish. Bummed me out when it came apart.

Kingsley North has silicon carbide belts and discs the harder the stone the more steps you need in polishing it up to a liquid shine soft stones don't need that many obsidian is one of the stones that need extra steps to get a good polish

Hey James I kmow the owner n can go anytime without it being a open dig, Chris trusts me, you still pay $35 for thr day but you get all you wanna carry up out the pit. Pm me James I got some ubneed to own n I send you a big box full just to get a handful of those pretty heated coral to play with making cabs. We take gingerkid with us n have our own personal dig. Need to go after a hard rain, surface prospecting is better then.

I see you live in NC. Klingspore Abrasives in Hickory, NC is a good place to order SC wet/dry belts from. And if you would like to give Diamond belts a try, Beeson's Hardware in High Point, NC (phone: 336-821-2100 and ask for the industrial division) will special order them for you at reasonable prices. I buy my 3M diamond cloth belts (651WY series) from Beeson's.

I am impressed w/the cabs.Well done man.I want to go to Hogg w/you.My place is on the way and you can load up on coral or i can send it.I want to post pics of that crazy rose quartz vein. Try to get good pic of the rose quartz.It looks killer.I have over the years found no fracture chunks the size of hardballs in that place-course you know that. 70MPH front and 2-3 inch rain in 20 minutes out of the gulf just tore me up today.Hit gingerkid's area real bad.I was talking to Stan('s Knives) on the phone when it hit Slapout, Alabama.Named that because the country store was often 'slap out' of bread or what ever.

They had a machine dig last month with a trachoe and dug a boulder up James that was thevsize of a VW bug and the backside near the ground is pure facet n Chris dug two chunks out as big as softballs with no fractures! He told me how to find it!

You guys talk about the rose quartz, but don't mention the aquamarine. Is that just specimen grade, or is it suitable for cabbing?
Thanks, Nate

The aquamarine is milky blue on outside but some is as blue n clear as a pepsi can on the inside. I saw one 6 inches across and it got busted digging it out of the rose quattz n it was pure blue full of facet grade in cunks the size of marbles. The outside is usually rotten beryl. Saw a 350 pounder that the guy is afraid to cut. Me I am all about cuttin n lookin inside. It makes a pretty milky blue cab. Its in the rose quartz and really hard to find since no blasting is allowed cause it fractures everything. There are rose quartz boulders as big as a greyhound bus there. James got to see the Hogg in its glory days of huge beryl n aquamatine!

This arrowhead is most likely low grade aquamarine from the Hogg mine area.Found a lot of chips at this camp that looked like the material from the Hogg Mine.This camp was also extremely diverse in lithic materials in tool making.Peahtree City Georgia.Still kooking for the rose quartz projectile.

Wow, I'd like to get in on that!! I've been out there 3 times, but never got a softball sized chunk of pure, lol. I did get a chip of Aqua that I haven't done anything with. That's what I'd like to find some more of. The pink takes a great shine but you need to get everything out as you come up since it's clear. Nothing to hide the pits and scratches, and you will see them. A wise man once told me if you have scratches then you didn't spend enough time on 1200, and everything below it Tony..a bit up the road from La Grange.
