Thread: I Found It Over There

those look quite reasonably sized and fairly flat. I have to admit I have never tried a flapper. I'm going to have to put one on my shopping list by the looks of it. Looking very nice indeed.

This is the flapper I was using.



Toolstation > Power Tool Accessories > Grinding Discs > Semi Flexible Disc

24 grit SiC. I was using it to take the big chunks off the top to get it level and to quickly sort the sides.

Looking good!

Harbor freight has good flappers for like 5 bucks

Snowed in so braved the walk to the jeep and grabbed a few of these

I need heat in my garage tho lol

Wish me luck these are the small ones

Good luck with those bud! You have some nice looking plates.

I think I found out what the first batch is BTW.

green diorite. It might show some promise as a polishing stone or a lapping stone the wiki recons it should be harder than granite!

Todays experimental cut of the Matterhorn lump. This was a split shard. I spit the big lump in 2 and this piece came from the incorrect grain angle due to the lump having a secondary crack at the edge causing a 90 degree plate to form. I knocked the plate off and it made this! The rest of the lump appear to have split in grain. I'm going to tackle one of the other lumps on Thursday and see if I can make good on this chunk of stone.

Todays working has given me a little more insight into this stone. Following the natural cracks and splitting the rock like you would with wood leaves you with a pretty good surface to start to work with. Also even in a small small cross grain lump like this you can see the different layers. Not all the layers are silky smooth, Some have grains that are sandy and black, Some are light, others are darker. The red spots appear to go through the grain by quite a depth and are not quite as layer locked as the particles.

that is a great looking piece. Sorry for my lack of pictures. Uploading is a bear with my poor internet speed. It takes five minutes whether or not it is successful. I will try some when I'm outside again. Right now I need to continue to work on a project for my dear sweet wife.

The stone looks like an actual Charnley stone.

So, I was searching the bay for stones, and as usual, I found someone selling an Asian inkstone as a "sharpening stone". And I love their instructions of use.
I read somewhere that in China, long ago, there was a great sharpening stone, and an emperor of that time liked that type for instones. And they stopped making them out of this.
I would be interested to try one of those stones, thus I searched for inkstones. And I found this, Oriental Vintage Rock Stone Handwork Plum spots of Duan Inkstone



I don't know if it can hone, but it sure looks like the twin brother of Charnley stones.

That is a really nice looking rock. I hope you ordered it. If it doesn't work as a hone it can be decorative piece, paperweight or aquarium piece. Better lap it and see.
