DIY wheel tracking

Depends how posh you want to be, i allways find a couple of lengths of string, a couple of axle stands and a measuring stick works but it helps if your on a ramp and can turn the wheels or have something for the wheels to turn slightly on.

In some situations i have used two sheets of metal lightly lubed, this acts as a free plate for the wheels to turn on, not the best but works well.

The string trick is very good.
