Guess we got away from the point
1 - if you want nice shaped rocks out of rough Buy a Rotary
2- If you only want to polish preforms or smooth sea shore stuff stick with your Vibe

learn2turn, I'm a noobie, so only entitled to a qualified opinion, but I'm currently kidding myself that if I start with stones that already have a desirable shape and all I need to do is knock of the edges and polish them up, the vib will do it for me. If you are working with small chunks of jasper that are already shaped by natural erosion or beach stones that are of an attractive shape, you have a chance to make part of the fascination the collection of things you want to enhance rather than going the entire process from fragmented stone to gem. I'm currently working with very erroded pieces of seashells (soft and easy to work), and beach stones (probably jasper or greenstone) that don't have rough edges, and are just in need of burnishing, polishing, and loving approval from admiring kids, friends, and spouses. Good luck and definitely pick something that will enhance time with that young one and get everyone out of doors sometimes. Tom

Hi Tom Yes rotaries realy take all the rough edges off and bring them into shape
If you use the Vibe it will retain the shape and polish
I put in pre cuts and they come out fine
But they are VERY agressive in 220 dont be fooled they would soon turn your shells into mud,
Only problem you could have would be as you say you are working on some very eroded pieces is to wash well a couple of times befor the next stage to make sure no grit gets taken over to cause a problem

Jasper that is very eroded adn well rounded onthe beach may be solid jasper that has beenthere a long time, or more likely altered (oxidized) softer jasper that will not take a polish.
