I have built the Momus CNC machine and my router died and needs to be replaced. I have been thinking of getting another bosh colt but I have also been looking at the 1.5kv spindle that is available online. I will provide a link. I have a few concerns about the spindle. Will it fit(colt is about 75mm and the spindle is 80mm)? Can the machine carry it(I cand find and spec on the weight of the spindle)? Is there any improvement over the $100 router to justify the extra cost? Is 1.5kv overkill(colt has 1Hp and the spindle has 2HP)? Any insight that can be provided would be a great help. Thanks in advance.
