Whiteboard Clamps
I figured a whiteboard would be useful for crude drawings, dimensions and noting hand wheel readings. As a bonus, the whiteboard I picked up is magnetic, so I can post printed AutoCad drawings as well. The aluminum posts on my workbench have T slots, so it is easy to attach things to them. I made some simple clamps and T nuts out of aluminum bar stock. After turning the major diameter, I used the mill to drill the holes, shape the T nuts and cut the slot for the whiteboard.
