It’s download day here at Ceramic Arts Daily! Today we are offering a great new e-book packed with techniques and tips designed to help you get the most out of your pottery wheel. And as usual, I am going to give you a little sample of what’s included.
If you’ve ever tried to throw multiple pots of the same size and shape, you know that it’s tough to just eyeball it. Sure, calipers can do the trick, but if you are on such a tight deadline that every second counts, it is nice to not have to stop what you are doing to measure. That’s where a throwing gauge comes in handy. Today, Don Adamatis demonstrates how to construct a simple, easy-to-make throwing gauge. And for more great tidbits, download your free copy of Tips, Techniques and Tools for Getting the Most Out of Your Pottery Wheel: From Centering to Trimming, Tips for the Potter’s Wheel!
For the potter who wants to make their own throwing gauge, it’s easier than you think. This simple tool can be constructed from inexpensive materials and can be used for other purposes besides throwing duplicate forms. I use mine to lay out designs on leather-hard pots for carving and on bisqueware for glaze decoration.
First establish the size (diameter and height) and profile of the form, and determine the amount of clay needed for each piece. Once this is accomplished, throw the first form in the series. While it is still on the wheel, set the gauge tip to mark the diameter and height. Remove the first piece, and center the next ball of clay. Open it, pull the wall and shape the form until the edge of the lip meets the tip of the throwing gauge. Repeat this for each form in the series. If necessary, use a rib to define the profile.

|A T-bevel with a 9-inch adjustable blade (these are readily available at home improvement stores); galvanized T-fitting; epoxy-type glue.|
|Place the adjustable bevel on the galvanized T-fitting so the adjustable extension blade lines parallel up with one side of the T fitting. Glue the base of the bevel to the fitting.|
|The throwing gauge is placed in front of the wheel head (out of the way) and adjusted to the dimensions required. The gauge could be mounted on a brick if more height is needed. Each piece is pulled and shaped to match the tip of the gauge.|
|The gauge can be used in combination with a division chart to mark off equal sections of the pot for decoration.|
