The knob on my plunge router is small and hard to turn. To make it easier to use, I came up with a simple hand crank. The crank is nothing more than a piece of plywood with a large hole to match the size of the knob, see drawing at right.
I cut a slit in the edge of the plywood crank and then used a screw to pinch the crank around the knob on the router, see detail.
To make a handle for the crank, I drilled a hole lengthwise through a short wood dowel. Finally, a carriage bolt, washer, and jam nut secure the handle to the crank.
With this crank installed on my router, it's now a lot easier to make adjustments to the height of the bit.
Have a nice weekend,
