This is an awesome tool for frustrated artists.  Currently using it to rough out bowls from green Basswood.  Putting the disk on is annoying.  It's two big washers and a loop of chain so it keeps falling apart.  If you are using a variety of grinder tools just buy a second $25 grinder and leave it on.  It is a chainsaw tool so a disaster waiting to happen.  Wear protective gear and keep in mind the location of your important parts.  I believe there is a double chain version which I'll purchase next.  Nice complement to a chainsaw for artistry.  Not sure if 'grinder art' qualifies as 'chainsaw art.'
