Not sure what your thinking of cutting but I doubt you need a 2.5Kw spindle The reason I say this is you wont be able to plunge or travel at a speed that will put the kinds of loads on the spindle that will need that level of power. To put it another way your going to use a spindle that is roughly equivalent to a 5 - 7.5Kw router. Id suggest you start with a 500-800W unit with a 1.5Kw unit Max Im putting together a 1.5Kw unit now but that is because I had one spare. If I was to buy one Id get a 500W unit. Now I have a 3.5Kw unit on my big table (not Maslow) but that is able to load the spindle up with a much higher travel rate and a fixed gantry Take a read of this thread as I post a lot of info on this and the bits needed > [@Best place for Variable frequency Drive Box for spindle](https://forums.maslowcnc.com/t/best-place-for-variable-frequency-drive-box-for-spindle/5263/6): > > Thanks, I come from a manufacturing background mostly in metal and lots of cnc gear Here is a good link that explains the differences well The only other point is cost While a router may seem a lower cost option I dont think it is really Lets say you start with a bosch pof 1200 ae router. I will use Aussie prices here You to spend around $150 for the router and another $100-150 modifying it to use the z axis. So lets say $300 for the router For a spindle you will spend $110 on the spindle… Also from the links it appears you are in OZ, not sure where, Im on the Sunshine Coast --- _[View the full topic](https://forums.maslowcnc.com/t/over-sized-over-engineered-spindle-z-axis/5442)._
