Lovely crosses as always Dan!
ejs: Remember that diamond blades meant for lapidary dont actually "cut", they just grind. And its a good thing too because I touch my blades all the time. I'd have no fingers left if they cut lol. The only time I bled was when I first started cabbing and I was using a flat lap styled cabber. I was just grinding away and all of a sudden there was blood on the lap.

Dan - I've always loved your crosses! These ones are fantastic... ejs - In a vibe, these crosses would have a more defined edge between the sides and the face/back. In a rotary, that edge is much more rounded. Shapes do survive in a rotary, but if you're wanting more detail/sharp edges, then a vibe is the way to go. It's a preference thing. Only Dan would know the breakage rate of the crosses, but I imagine they pretty much all survive.  Colliel82 - someone did just that with their WF. I can't remember who, though! It was quite the professional looking job, too... |

Is there any extra care when doing crosses... like adding more filler so they don't get beat up? I have a rotary, but I don't use it too much. I have so much more experience with the vibe, it's always my first choice in tumblers. |

Thanks for the interest guys... I'll try to answer some of the questions.
They are tumble polished and I do take a little bit pf extra care to cushion the load... just like any other tumble... you'll want to use some baroque stones of various sizes in the load.... I use plastic pellets as well in all stages.
The reason I like to tumble them is because of the rounded edges that a rotary provides.... I find it's easier to wrap them with a rounded edge. The trick I use to make the cross secure in the wrap is dependant upon the edges being slightly rounded.
The crosses normally survive the rotary tumble easily.... If they survive the cutting process than they usually survive the tumbler.... I'd say I have a 98% success rate once they get into the tumbler. In fact I can only think of 2 that didn't make it through....
YorkShire Jack made an "angled shim" wedge for defeating the overcut problem on his saw... the wedge ensures that the stone hits the edge of the blade at a 90 degree angle... I can't remember where that thread is though... maybe Jack will post the link here...
Hope that answers all the questions.... of course there might be better ways to do them but the process I use seems to work for me...
Thanks again all,
Dan
