Measuring Camber Angle

Following on from a previous post
( about the benefits of a small Camber Angle i decided i would measure the camber angle on my MGB.
I cut a length of wood to just fit inside the wheel rim. Using a level a measured the gap on the top edge of the rim when the level was centred.
Using a bit of geometry (or a phone app) you can work out the angle. In my case it was about 1.4deg.
This is about right for a lowered RB suspension.
