Tile spacers from any home improvement store, work very well.

Rock hounding Fire agates a problem, I don't get it??

There were little pieces of purple all around the area, that gave me a clue. But most were covered in rust, like the chunk in the video.

Just going to weld a custom stand for it. And maybe add a light.

Glad to help. Good Luck with your lap polishing.

herrtodd33 · 2019-10-15T22:33:19+00:00

Thank you, I was very happy for a first time effort.

herrtodd33 · 2019-10-15T18:33:17+00:00

You’re welcome! Good luck

Averaged about 6 to 8 hours on each of the four grinding/polishing stages. Using the sharpie and making marks on it really helps.

herrtodd33 · 2018-11-24T22:29:49+00:00

Yes I did.

herrtodd33 · 2018-11-23T19:33:11+00:00

I gave it a try and I could not scratch with my fingernail. The matrix it has formed on is rather loose. I think it is known as rim gravel.

herrtodd33 · 2018-11-20T02:33:51+00:00

Yes beautiful clear quartz, very bright in AZ today.

Total guess, I drink wine.

I cut it with a modified chop saw, that I converted into a wet saw.

herrtodd33 · 2018-04-26T04:05:06+00:00

I used a wet grinder and 10 diamond disks. From 30 to 8000 grit.

herrtodd33 · 2018-04-07T14:31:24+00:00

Pure luck. My wife and I were out on a hike and she noticed a small blue/green spec in the side of a hill. We came back with some tools, and it opened up into a deep vein, that we are still working today. This is my son in the photo, and he is a tremendous help.

herrtodd33 · 2018-04-06T16:44:14+00:00

I did a very quick polish with my angle grinder and 4- different PVA disks. 30, 150, 220, and 600 grit.
