Chinese 1.5kw Spindle

[WB-1]

Hi guys, just received my spindle the other day and noticed there was know way of earthing the spindle with only a three pin connector.

Just wondering what others have done to earth their spindles. Hate to think what would happen if a lost a phase to the spindle frame.

I managed to find a four pin connector which was identical to the three pin and have changed them over. I was going to solder my earth to stainless steel frame but stainless steel doesn't solder so good. Might end up drilling a hole through the side and nut and bolting it.
