Woodworker's Best Friend

When woodworkers are setting up their machines, they are always having to measure height. There are quite a few gizmos out there for doing this, but many are just to complex or bulky to use. This is especially true when the woodworker is faced with adjusting and truing the bed rollers on a thickness planer. This device will make them smile.
It can also be used to set the height of a saw blade or router bit in the router table. If yoy have a woodworker friend, this would be an ideal gift.
