I too, am just looking at replacing the spindle on an old Step 4 router. Looked at the BPP 0.8 watercooled 1.5kw VFD. Since I am replacing a little Proxon router spindle, I have no idea of the additional requirements to drive this new spindle. I am not electrically very competant?? If anyone would be kind enough to explain the implementation of the water cooled system, I would be most grateful.
I have been running with my Kress spindle, but that is a bit too heavy and some mild flexation is evident (not unsurprisingly) if I overdo the load.
Once again I would be grateful for any assistance.
