MEASURING YOUR WHEELHEAD

When ordering pottery batts or systems, we always recommend that you measure your own wheelhead yourself. Please don't assume that the manufacturer's information is accurate because sometimes there can be minor variations, and each wheel is different.

Select from the standard sizes given on our website.  If you don't see your size, just choose the closest available option, and then enter your own measurements in the 'Bespoke' design box on the product page.  We will make you something custom fit.

Measuring Wheels WITHOUT batt pins;

Take a look at the video below for guidance on measuring your wheelhead with NO Batt pins.

Our Over-the-Wheel Tile Batt Systems have been created especially for wheels with NO batt pins.  They are specifically designed to be slightly bigger than your wheelhead measurement. This is essential in order for the master batt to go on and off easily. It is quite normal to have a millimetre or so of movement when you put your master batt on the wheel. When the wheel starts spinning, and the wet batt rug is in place, there will be no excess movement. This is part of the unique design. 

Measuring Wheels WITH Batt Pins.

When ordering a batt system for Pottery Wheels WITH batt pins, please provide your measurements A to D as described in the video below.


You will also need to measure the diameter of your batt pin bolts.  (See below for further guidance).  

We recommend that you always use a good quality, metal, measuring tape or ruler such as the one shown below. (Click on the link to view).

Measuring your wheelhead if it has Batt Pin Bolts.

1) Measure from position A to position D using an accurate tape measure / rule.

2)  From the left perimeter of the wheel head (A) to the centre of the first batt pin head (B).

3)  From the centre of the first batt pinhead (B) to the centre of the second batt pinhead (C).

4)  From the centre of the second batt pinhead (C) to the right perimeter of the wheel head (D).

5)  If you add up measurements 1,2,3,& 4 the total number should be the same as your wheel head.

Diameter of Batt Pin Bolts

Measure the diameter of your batt pin bolt heads using an accurate metal measuring tape.  The most common batt pin sizes are 9mm and 10mm.  These are listed in the drop down box options on the product pages.  If you don't see your size there, please just enter it in the 'Bespoke' box and we will create something custom fit. 

If you have imperial bolts (1/4 inch bolts / 6.2mm), or old batt pins which are not the standard metric size, please just let us know by entering your own measurement in the 'Bespoke' box.   ​​​​​​​ We can cut your batt pin holes the same size as your batt pin bolt head plus 0.2mm.

It is important that we get the sizing of your batt pin bolt heads correct, so please ensure that you measure accurately. We recommend the Batt Pin size is measured using a tool such as Vernier Caliper (as shown in the link below).
