MEASURING YOUR WHEELHEAD
When ordering pottery batts or systems, please measure your own wheelhead. Do not use the manufacturer's information because there can be variations, and every wheel is different.
Once you have measured your wheel, please select from the standard sizes given on our website. OR 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.
1) How to measure your wheel if it DOES NOT have batt pin bolts
The video below shows you how to measure a pottery wheelhead that does not have 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.
2) How to measure your wheel is it DOES have batt pin bolts
Some pottery wheels have batt pin bolts in the wheelhead. These are designed so you can secure batts and batt systems onto the bolts on the wheel. They are small bolts that stick out of the wheel (as shown in the image below).
If you are ordering a batt system for a pottery wheel that has batt pin bolts, you will need to measure the diameter and location of your batt pin bolt heads. This is so that we can drill holes into the batt to fit over them.
The video below shows you how to measure a wheel that has batt pin bolts.
When placing your order, please select the size that matches your measurements. If your wheel size is not listed in the drop down box options, please just tell us:
* Your measurements A to D as described in the video, and the diagram below.
AND
* The diameter of your batt pin bolts.
You can write these measurements in the 'Bespoke Design' box, in the comments at the checkout. If you'd like some help Click Here to contact us.
How to measure your wheelhead if it has Batt Pin Bolts
-
Take a look at the diagram below.
-
Measure from position A to position D using an accurate tape measure / ruler.
-
From the left perimeter of the wheel head (A) to the centre of the first batt pin head (B).
-
From the centre of the first batt pinhead (B) to the centre of the second batt pinhead (C).
-
From the centre of the second batt pinhead (C) to the right perimeter of the wheel head (D).
-
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. The image below shows the ruler being taken straight through the centre of the bolt. You can see that this particular bolt is 9.5mm.
If your bolts are not 9mm or 10mm diameter, please just let us know by entering your own measurement in the 'Bespoke' box, or writing it in the comments at the checkout. We will cut precision batt pin holes that are 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. Use a metal ruler as shown in the picture above, or a tool such as Vernier Caliper (Click here to buy).
When measuring your wheelhead always use a good, accurate ruler such as the one shown below. Click here to purchase. Please don't use a 30cm ruler if your wheelhead is bigger - always choose a big enough ruler (otherwise your measurement may be inaccurate).
Please note that if an order is placed with bespoke features / sizes requested it will not be possible to offer any exchange products or refunds unless the items supplied are faulty or do not meet the ordered specification.
