I believe I have gotten all of the parts I need to create this but I do have a couple of clarification questions.
On this item, the magnet they provide looks like it won't work well with my Atlas lathe. Can I just get a small rare earth magnet which I can install behind the gear on the far left of the spindle (bull gear?)? I am assuming it just detects a magnetic field, it really doesn't care what provides it.
Second, I am going to be using a modified PC power supply to power the tach with 10v DC. I would like to run a relay to shut that power supply off when the lathe is not running. I know enough to know generally what I need but I would appreciate a suggestion as to an inexpensive relay for cutting the power when the switch is turned off.
Thanks in advance for any suggestions.
