RaT it would be nothing but a thing for you. I guarantee it.
But let's for the sake of argument say you might be a trifle nervous about your ability to draw.
I can relate to that. Life's a b-b-b-b-b-b-bear when you want to be an artist and can't draw. /forums/images/graemlins/tongue.gif
Based upon what you've said about working with sandstone I'd suggest that. Let's pretend you have a computer with a printer. Then let's pretend you have an office supply somewhere in town. If you had those two things then you could find some clear plastic sheets. If you have access to the internet /forums/images/graemlins/grin.gif /forums/images/graemlins/grin.gif /forums/images/graemlins/grin.gif you can find a free clip art coyote with his head up, mouth open, in love, most likely. Print out your coyote clip art on the clear plastic sheet. Find a friend, bud, cop, fireman, city council person who has access to an overhead projector. Do your image final scale on something stiff and durable.
Transfer image to stone. Get after it.
A good source for stones, grinding discs, cutting blades, etc, all for 5/8--11 small grinders is
www.granitecitytools.com Prices are great and they're nice people.
Let's say you have a three inch thick piece of stone. For the sake of argument let's say you drill two three sixteenths holes through the stone. You now have a method to index your drawing on both sides. A twenty dollar cutting blade on your angle grinder will allow you to cut in a half inch following your pattern on both sides. If your stone is sound you can now carefully hammer and chisel out your silhouette.
A sixty grit stone, about ten dollars, will finish out the chisel and cut marks muy bueno. Or if you want a really trick look keep the chisel marks and also chisel out your cut marks. Make it look like you not only knew what you were doing but you did it the hard way.
Heck I'm having fun just thinking about it. /forums/images/graemlins/smirk.gif
