I'm going to progress this hobby now and i'm going to have a go at cutting and shaping some of the rocks.

I have a tile saw, which I guess is OK for cutting the rocks, but, and this is the clincher question, is a general purpose bench grinder with course and medium discs suitable?

Such as this one here img.en.china.cn/0/0,0,59,16480,370,370,0d5bc00b.jpg

Most of the lapidary wheels are designed to run at 1725 rpm. Bob

(I have one). You'll need a silicon carbide wheel that's made specifically for lapidary use, they can be purchased for around $25 online.

rocknrob: That was one heck of a windstorm that thankfully missed me. I guess Seatac almost hit 60mph gusts. I bet those were some fun landings Nov 20, 2024 21:55:16 GMT -5
