I Found It Over There

I'm joining in on the rock hound :beer1:

and in answer to the statement in the title of this thread: I found it near Fontaine Bleau, which is a world famous bouldering area about 80 km south of Paris. the boulders around this place are made of sandstone, but a lot of them have a sort of shell partially around them made of metamorphised sandstone I guess, These boulders are way to big to take home (we go there to climb these boulders) and aren't very usefull as razor hones since they would be way to course.

this is me trying to climb one of them:

luckely a lot of the smaller rocks at the campsite are some type of metamorphised sandstone and could be quite usefull.

so I took this piece of rock home with me, it seems to be a flint stone to me which should have a nice cryotocristalline morphology which I hope will turn into something usefull

this is the piece I took home

now for me this will be the difficult part: turning this rock into a hone, at my disposal, a dremel with a small diamond blade...

I'm going to try and make a cut around the rock and then try to split it using a wig type of metal or maybe fryzing it while submurged in water, don't know yet

If you have one use an angle grinder, If you don't and want to keep things as cheap as possible get a tile blade for a 12" hacksaw.

Isnt anybody of our Rockhounds interested in researching The "Magog" Oilstone....there is quite enough information to possibly find the layer somewhere around Lake Memphremagog...for shure a little bit research must be done in the area...and also it was mentioned that the layer might only be accessible in certain period thru the year as the water is to high on the other time...

I would do....but living in germany is quite difficult :-) anybody living there near by ?

A coarse stone could perhaps be a bevel setter, which are very rare in the naturals.

Shaun, not really....as been written by Neil Miller and posted by Hatzicho it seems to be a finishing one....very slow and in the range of 8k-12k

OOps, sorry Sebastian, I had intended my comment for Bram. I should have been more clear when I posted that. I did read that the Magog was a finishing stone.

I would think sandstone could be a bevelsetter although what I found over there was course even for bevel setters. besides, the sample of sand stone I did split had a realy loose matrix and seemed a bit crappy to me so I didn't take it with me.

@ Doorsch, Lake Memphremagog is a bit far from me as well :P

@Iceni, thanks for the advice but so far I've managed to make a 1/2 inch cut in one half of the stone, I'm going to make this cut continuous around the stone and then submerge it in water and freeze it. if that doesn't do anything I'm just going to try to lone an angle grinder from someone. by the way, how are your charnly forest hones comming along?

All the sandstone I ever find is really loose like that as well

Finally back to working on my slates...Gonzo and Rezdog next in line....

Last one we've rated around 12-15k...hope I can duplicate it....this rock is from same spot.

Anywho some pics of the beast I'm working on. 6"x3"
Couple low spots I'm still lapping out but taking a break.

Honestly may be finer than the other I made...the sparkles are smaller in this stone than in my other stone
