Make itWe need a separate thread for this stuff.
One thing to add about spindles is... if you use a hardware store style router - dewalt, makita, etc - whatever it says for power on the label is basically a lie. What they will often tell you is the max power draw it can pull before tripping. Usually that's well beyond when your fuse will blow, and could only be sustained for a second or 2 in use.
A "real" spindle gives you the power OUTPUT and is rated for continuous operation for hours on end at that load. They often also give a secondary rating, for intermittent usage. often 25% over the other rating, for 10 or 30 minutes.
So a teknomotor 750w (1hp) spindle will in reality have 2 or even 3 times the real usable power of a "1hp" bosch colt.
So, i guess i should rephrase and say the spindle is rarely the limiting factor, if you know what the spindle's limit actualy is.
