Make a Tiny Benchtop Grinder
Here’s a neat way to free up your hands when using a rotary tool for sharpening and other delicate jobs. Screw an angle bracket to a board and attach the rotary tool to the bracket with a couple of radiator hose clamps. Don’t tighten them too much or you’ll damage the tool housing. The board lets you clamp the tool either vertically or horizontally.
