[Noisebridge-discuss] drill press table

[Chris Murphy]

I add that there is a depth gauge on the left side that amateur people keep removing for no good reason. It uses an M6 nut. It needs thread lock and a sign that says Do Not Remove the Depth Gauge! 

The gauge is the threaded vertical rod in the top of this photo.
