man, that was a long thread to read through....but lots of interesting things here
I'll be honest, half of it it above my head, but two thoughts come to mind while reading
re: making hones with powdered abrasives and a bonding agent-
Rather than mixing into a clay type resin and hoping for even distribution of the abrasive, has anyone tried making a mold filled with the powder and using a vacuum assisted resin infusion method to pull a liquid resin through it? I don't know if it could be done without sucking out a powder this fine, I'm just curious if it could work using a realllly fine filter material covering the 'suction end'.
I'd imagine it would make for a rather high abrasive to resin ratio which, if I'm reading this stuff right, would make for a rather fast cutting stone...maybe too fast for a finishing stone
re: found materials-
The talk about using old slate chalk boards made me wonder...has anyone tried getting their hands on an old slate pool table top? A good one should be made of a very hard, extremely flat slate, about an inch thick. I hear the good ones are often Italian slate, don't know how true, or if that means anything good or bad to anyone here?
Wouldn't be easy, but if you can find someone with a broken slab that can't be repaired, an average 8' table with a 3 piece slab...each piece would be approximately 51" x 31". That's 60 potential 8x3 hones (minus whatever is lost where the slab was broken) out of just a third of one table
Those are my thoughts....other than that, I'm loving just looking at some of the rocks you guys are coming up with. Keep up the good work!
