Pot Bottom Grinder Pads for Pottery Wheel, Production Grinder

Pot Bottom Grinder Disks for Pottery Wheel
This method uses 12 inch diameter silicon carbide grinding discs with a peel-off adhesive backing.  You affix this disc to any 12 inch bat which is then attached to the wheel head.  Grinding is done at the fastest wheel head speed.  The 50 grit takes off material fastest (including small glaze drips) while the 80 grit gives the smoothest finish.  It's alright to use water on the grinding surface.

Advantages
Grinds smooth the surface that actually touches the table.
Low initial cost - you already have the machine (your wheel).
Grinds bottoms flat so the piece won't rock.
Disadvantages
Higher cost per belt/disc and lower production rates. Example, 10 seconds per mug bottom.

High Production Grinding Kit

This method uses a 3 inch wide silicon carbide grinding belt. These belts are slid over a special rubber-backed grinder. The grinder is mounted on the arbor shaft which is installed on the shaft of a 1/3 hp. motor complete with cord and switch.

Advantages 

Lower cost per belt/disc and high production rate.  Example, 2 seconds per mug bottom.
Because of the flexibility of the belt and rubber backing, this system grinds the entire bottom of the piece-smooth as silk.
Also grinds off glaze drippings and jagged edges
You can grind into the foot of the pot.

Grinder, arbor shaft and motor
