If you know how to make a homemade wedging table with canvas and plaster surfaces or you can buy one, you'll save time and effort in your pottery.
Wedging Board or Table - A sturdy table for preparing clay for pottery making.
Usually includes a built in clay cutting wire, a canvas surface for wedging clay, and a plaster surface for drying and reconstituting used clay.
A good table should be very sturdy. You're going to be leaning and pounding on it, and you don't want it wobbling or sagging.
It should also have adjustable legs, or at the very least be customized to your height.
It should be low enough that you can lean downward on the wedging surface, using your body weight rather than your muscles to work the clay.
Above is a photo of a Debcor Wedging Board.
This board can be purchased with or without the stand. The stand has adjustable legs.
If making your own homemade table, use a hardwood to build a box.
You can mix your own plaster and pour it into the box for one side.
Then wrap canvas around the other half of the table surface and tack or staple it to the underside to secure it.
You can even purchase a cutting wire frame to hold the wire tight.
