Dial Indicator warning light
Posted: Wed Dec 06, 2017 4:54 pm
Being too cheap to buy a set of DRO's for my ancient horizontal mill, I use a dial indicator on my z axis. Well I have damaged a couple of them because I apparently can't think, crank and watch at the same time. So after I bought a 2" travel dial indicator it was time to put a warning light on it so it would tell me when I was nearing the end of the stroke.
Here are pics of how it works. Approaching the limit

Powered by one of those $2.75 dog collar flasher units available at your local store. I had to make up the switch body and contacts, but it works very well.
The flasher unit is the flat doodad in the center: an integrated circuit board with 2 alternating flashing LEDs. The whole assembly slides up and down on a mini-track found at your local woodworking shop and is locked in place by clamps.
Another project finished and perhaps a DI off the injured list to boot.
