Newbie Questions Re X2 Mini Mill

[royesses]

I'm using this for spindle speed... No batteries to buy and I can't misplace it.

I'm using the [URL='http://www.machtach.com/']MachTach kit for rpm and surface speed. I love it. [/URL]

The kit is very easy to assemble. You must solder components and wires on the circuit boards. I taught high reliability soldering and board repair at the local vo-tech and for an Aircraft manufacturer repair shop so it may seem simple for me but anyone can learn to solder quickly. I use the optional wall wart to power the tachs.

I used the magnetic pickup option and made a mag ring and housing to mount on the lower spindle bearing cover.

I also added a set of flood lamps and touch switch.



I also have the MachTach on the mini lathe.
