Rock's - The Bull Wheel

The Bull Wheel is a time tested grinding machine that gets the job done fast. It can do in minutes what it takes hours for other machines to do. Ideal for slabs, nub ends, chunks, book ends, nodules halves, geode halves, shelf specimens, etc...   A Note about this machine and our lapidary shop - This is the machine we use to polish geodes, petrified wood specimens, and other flat cut rock specimens off of our saws.  We use a vibrating lap to remove the saw marks from the saw.  Then all we have to do  is a quick dry sand step on the bull wheel to bring up a nice smooth sanded gloss.  We then polish them on carpet on our vibrating lap.  A quick process that works great for us with a minimal amount of hand work.
