Drill press laser guide

This is a drill press laser guide that fits on a 50 year old 3in (actually a column of 2-7/8") American Intl press drill.

I used the tapered laser holders and nuts from https://www.thingiverse.com/thing:3354013 (credits to SBKirby) and made a fully customised support to fit the lasers and power supply on the 3in American Intl press drill. A worm gear clamp is used to hold the laser and power supply bracket against the column.

I used two standard 12mm 650nm 5V 5mw line laser and a 9x14mm SPST switch and a universal AC/DC power module to generate the 5V for the laser, all from AliExpress.

I drilled a small hole into the drill press body to get the 120v power wire out behind the drill power switch up the laser switch. Add a bit of soldering & shrink tubing to complete the magic.

I used a small weight & a white rope in the chuck to perform the vertical alignment of the lasers against the center line so it's always good with the table up or down (tricky part).
