hey moose eater, I smoked out of that sandstone at a Christmas party with a few old guys. we broke in that pipe and it hit great and never got hot that we noticed.
I've been wondering if I could get a local dispensary to sell them or sell them online or something as a business, but I'm not sure.
finishing up the black one i was marking on in the above post.
in an earlier post i showed the rock and blank this one came from and had it marked for cutting. here the bowl is drilled, and chipped out. the rest is likely to break the edge of the bowl,(which sucks) so I have to grind the rest of the material out.
Grinding the bowl with a sintered burr. so muck better than using worn 5 mm bits and things. still though, the plated burrs are better for rounding the edges of the bowl. but the sintered burr is way better for the bottom. The last pic shows it done.
the guy loves it.
a couple guys have asked me about getting one. i will be sending them out soon. fear not.
