Finally I got the Ameritool cabbing machine today, it was released from being hostage at the post office after I paid 80 Euros fees. Couldn't wait to come home from work and start playing with it. I've set it up, took a piece of morrisonite that Amy sent me a while ago in box with other rocks, and started grinding away at it.
First of all, I have to say that working on the machine is extremely relaxing, very quiet actually and really rewarding when you see the piece of rock starting to shape and smoothen up. So now the last doubt about buying the machine is gone as well, as I truly enjoyed polishing up this stone.
The result is not something spectacular, but it's special to me, as it's my first cab :)
