Frequently Asked Questions

My Giffin Grip is off center, what’s wrong? 

  1. Wiggle your pot!  Once all three Sliders or Rods with Hands make contact with your pot, give it a wiggle (and tighten once more).  This helps to create equal pressure on all three sides and places the pot as close to true-center as possible.  *Note: The Giffin Grip is not perfect and there has always been some variation from true-center.  "It's as good as I know how to make it!" -Brian Giffin 

  2. If it is still problematic, check that all three Bottom Brackets on the bottom are set to the same notch.  If they are, and your Giffin Grip still appears off center, you may need replacement Bottom Brackets.  Sometimes one of these brackets gets bent over time and replacing them usually solves the problem.  You can find them on our parts page free of charge for all Giffin Grip owners. 


Will the Giffin Grip fit my wheel?

The Giffin Grip fits most potter’s wheels on the market including: Shimpo, Brent, Speedball, Skutt, and many more. Any potter’s wheel with a removable splash pan, or sufficient side clearance to mount a 16” (42cm) diameter round plate on top can accommodate a Giffin Grip. The Giffin Grip can be adapted to wheelheads from 8.5” to 14” in diameter. After a simple, one-time adjustment, the Giffin Grip quickly snaps on and off your wheel.

 

Does the Giffin Grip come in both clockwise and counter-clockwise versions?

Yes! The Giffin Grip comes in two versions, one for working on Counterclockwise turning wheels (U.S. STANDARD) and one for working on Clockwise turning wheels (primarily used in JAPAN).   


Is there a Giffin Grip Guarantee?

Yes! We stand by our 90 day money-back guarantee and 10 years free replacement on parts that wear out or break in normal studio use.

How are the Basic Sliders different from the Wide Sliders?

Basic Sliders are for the majority of the pots. They can either hold the base of the pot or higher on the pot using our Rods with Hands for taller pieces.

Wide Sliders extend the diameter of reach towards the edge of the wheel in order to accommodate larger plates and bowls. For platters over 14 inches, we offer the Jumbo Platter Extender.  It combines with the Giffin Grip Model 10 to hold larger work.


How does the Jumbo Platter Extender work?

The Jumbo Platter Extender fits on top of Giffin Grip Model 10 (similar to a bat). allows for trimming platters up to 58 centimeters (23 inches) in diameter.  Three brass bat pins drop into the 3 grooves of the Top Plate and specially designed Jumbo Sliders engage with the spirals on the bottom plate.


How do I know this is the Authentic Giffin Grip?

The Authentic Giffin Grip Model 10 is manufactured in the USA.  It will have our logo imprinted on the Bottom Plate and read:

GIFFIN EARTHWORKS INC. - PO Box 4057 -  BOULDER, COLORADO - 80306 USA

The Giffin Grip Mini™ will also show our company name and patent information.
