Magnetized mill spindle generating static electricity??

For anyone looking for this information in the future, here's what I did to fix this issue. I used a standard benchtop plate demagnetizer on the spindle, I took the keys out and drug it across the spindle nose 3 or 4 times, this completely removed any magnetism in the spindle. This did not remove the static charge issue and I still had the static discharge spark between the spindle shaft and basically every other part of the machine that made contact with it. To fix this I put a temporary brush setup on the spindle at the top where there was room, I will be getting a brush kit from Helwig carbon, I spoke with them and they have a brush kit that will do what we need and they state a 10 year life span. Hopefully this helps someone in the future that may see some of these issues.
