So I saw a video on youtube and thought oh I could do that. Stone bead try 1 and 3. 2 did not survive. by Stone Turner, on Flickr well turns out Not so much. while I did make two beads (did not bother to polish) and a third that broke in half. My technique needs improvement. I want a round bead these are not even close. Whats produced in the video looks rounder and is alot harder material than what I used. Part of that is my tools. The first part was not much trouble. Some breakout on the back side due to carelessness then I broke the bit i was using to drill hole. The cheap diamond hole saws I got from china are still doing awesome thou. The big problem I was having was in holding the beads. I can not tell if the beads are spinning in the video when they are shaping it but after my attempts I would say they are. Tried shaping one stationary with a dremel and it was not effective. Using a bamboo skewer and drill press with some sand paper worked much better. Anyways does anyone have any ideas for holding the bead from the hole? I thought of a pin vise but that doesnt work like I thought it did. The Lopacki bead making tutorial comes to mind but he uses a pin vise, I am thinking of something that will tighten from inside the hole to hold on to the bead. also his doesnt seem suited to a round bead. They make it look very easy but obviously practice makes perfect or in this case round beads. I have alternative ideas I will try based around doing it this way.

You could try some soft dop wax. Are you aware that the bead is being rotated (at 6:15 in the video) at the same time as the angle grinder is being applied. Am I even correct? However, the bead appears to be fastened to a motor at this point. I'm pleased to see dry working without respirators ... RTFM

Any craft with a worthwhile ending tends to be perfected and that means the development of skills is usually required and that is oft achieved through practice... I wonder if your self observed no-so-round beads are not a result of having such a soft medium to work with. I know that getting a round top to turquoise cabochons can be very difficult as each pass over my flat lap tends to impart a locally flat trace.

Yes I was believing the bead spins while the angle grinder is being applied. I have a spare motor from a tumbler to achieve this but mounting the bead is a problem. It looks like they are just friction fitting the bead to the motor and applying the angle grinder. I need to find a better mount than bamboo skewers I didnt think that because i started with the softer stuff i might be taking more off leading to un round beads but it makes sense.
