I'm a bit of an ignoramus when it comes to spindles, so be patient with my questions.
My inference from various posts is that a 3HP spindle is at least half again as powerful as the PC7518 router and that it will do a better job of maintaining power at varying speeds. So, if the PC7518 is doing the job for me and seldom bogging down, a 3HP spindle as opposed to something more powerful would probably take care of most needs?
And, further to that, if you were pushing that spindle or something even beefier through heavy cuts, do you have an increased possibility of missing steps or over working your steppers (I have a PRT4896)?
OK, so I if I had a bare 3HP spindle in my hand, and I only have 220 single phase available, I would need a high frequency inverter to run it? And if I wanted variable speed, I would want a variable speed high frequency inverter? Or are they all variable speed? Would I need any other parts to complete the process?
I'm moderately skilled at wiring, would I need to or be smart to hire an electrician to wire up all the parts?
Any other considerations, thoughts on educating a novice as to the process of converting to a spindle?
Suggestions as to what it might cost for the parts over and above the bare spindle? Sources for new/used/reconditioned inverters?
Thanks in advance for your input!
