parts a wheel gauge; wheel blade, fence, stem, thumb screw and measurement markings

Wheel gauge wheel blade

Parts of a wheel gauge; wheel blade. the round blade rolls along the work piece to mark it The wheel gauge has a round wheel blade which is pulled along a workpiece in the same way as a regular cutting gauge. The round wheel blade can roll across the surface making it easier to keep an even line. The blade is also fully visible to the user, unlike with other gauges, this further helps the user remain accurate.

Like the knife of the cutting gauge, blade is bevelled on one side, this side should be facing the fence so it is on the waste side of your workpiece.

Wheel gauge with blade retracted into the fence to protect it when not in use When the gauge is not in use, the fence should be moved to the end of the stem where it covers the blade and protects it.

Wheel gauge fence

Parts of a wheel gauge; fence. fence holds the tools measurement and is weighted to stop it falling off work surfaces The fence of a wheel gauge is also circular, this allows it to move smoothly across the surface.

However, having a smaller fence means there is less surface area pushed up against the workpiece and this can lead to the tool slipping. The fence can move up and down the stem to hold a measurement but does not rotate.

Wheel gauge stem

Parts of wheel gauge; stem, main body of the tool The stem of a wheel gauge is a long cylindrical pole. The larger the gauge, the longer the stem is to allow it to reach greater distances.

Wheel gauge thumb screw

Parts of a wheel gauge; thumb screw, used to tighten the fence and hold it place when it is at the correct measurement. The wheel gauge has a thumb screw on the top of the fence. Once the fence has been moved into the desired position, the screw is turned clockwise to lock the fence in place.

Measurement graduations on a wheel gauge

Parts of a Wheel gauge; measurement markings The wheel gauge has markings along the stem to allow the user to measure out a length without a ruler.
Wheel gauge with metric, imperial and no marking graduations. Used to mark out where the gauge will mark when marking out a work piece The wheel gauge is available with either metric or imperial markings or with both one set on either side. They can also be available with no graduation markings at all, whereby the user simply uses their own judgement or a ruler for the measurement.

Collet and nut on a wheel gauge

Collet and nut of a wheel marking gauge Micro-adjust versions of the wheel gauge, named as such because they allow for tiny adjustment, also have a collet and nut. These sit behind the tools fence. Once the fence has been set the collet can be turned to give extra millimetre adjustment to make sure the mark is most accurate.
Using a wheel marking gauge for precision marking They do this by allowing the blade to be moved once it is already in position on the workpiece. For more information see How to use a Wheel Gauge?
