Unless you like cats, flowers and goldfish the fun starts about 47 seconds in.

I wish I would make one of those. Could really use one. Not the cat, fish or flowers.

That takes a lot of grit! What is the grit series? What polish? I can't see the jars on my small cell phone.

I'm guessing based on color and consistency, that the polish was cerium oxide. It needs to go on soupy. Maybe the message was really about fractal geometry, not stones or fish.

120-220-400-1000 of silicon carbide grit Polishing ceroxid powder.
For that setup I think i'd even tolerate the cat.

You could always throw the cat in with 60/90 grit.

I like the tire as a basin. The rest is simple....
How fast should a 24" lap spin? I will be at class tuesday night. Ill check!

Pretty cool. Wish he had added a caption saying how long a rock took from first grit through polish. Mel - Sabre52 - fast forward to the 11:00 minute mark and please comment of the rocks shown in the last 90 seconds of video.

The same guy published this a few months ago. I don't know what those little bricks are, but I want em!
I took a little inspiration from the vid. I took 2 tempered glass shelves from a fridge and have a 60-200 plate, and a polish plate. With hours of elbow grease I was able to level a piece of pyrite.

I can't believe I can watch someone rub a rock on a piece of glass/wheel for 11:00, minus some cat time, and then look to see if there's another. Unexplainably amusing.

I think the material is ocean jasper. I saw that hand polish too and am going to try it when my glass gets here, I've got a few bags of 50 year old grit and am going to splurge on some polish. Be sure to use tempered glass if you like your fingers.
captbob I think those are some kind of industrial diamond polishing blocks. I've been trying to source something similar on the cheap for the rough stage and will post if I have any luck.

I believe that he has uses the same or similar in building one of his mad scientist projects.

Mad scientist fast flat face machine. It will grind flats pretty fast. Same concept, just using diamond segments brazed to a wheel from Harbor Freight. Some results www.flickr.com/photos/67205364@N06/sets/72157648700305650China has now started making continuos diamond segment rings mounted on a cup. Must purchase: For final polish, diamond pads on walmart 5 inch grinders 100-200-400-800-1500-3000 Results from diamond pad machine. Polish does not show, but it is well polished.

Mad scientist indeed, thanks James. That thing just eats rock. The bench rig is cool and looks to give a very fine polish.
Is there a trick to setting the rock to the polishing wheels in order to keep it flat and not catch an edge on the segmented pads? Or is it even an issue when they're spinning?
And where do you get the diamond segments? I found some 6"x2" plated diamond blocks for about $10 each and was thinking of getting 3 and just laying them flat as a hand polishing surface, but it's possible that hand polishing is more fun in theory than in practice.

jamesp was an eager and significant adversary in the quest for Elin's love. I think he won. She likes the swarthy rugged type. Good service and quality product.

Persistant stalking and fake Fabio photos wins em over every time. That is a very professional gal. Pleasure doing business w/her. Best buys on diamond segment stuff.
