The Dremel is not accurate enough for a CNC machine where you want to know what your fit will be by numbers. But a Dremel that runs out a few thousandths is not a problem if you just take your time and use the right size stylus every time. By right size I do not mean one you calculated to do the job but one you test right then for precise fit. Just cut the pocket close then clean up the edge of the pocket and change decrease the size of the stylus a few thousandths at a time until the fit is right. As far as power goes I don't cut full depth in one pass and it has plenty of power. Oh how CNC has spoiled us. If it keeps on people will be using CNC turret lathes to do all rings and joint work. Will anyone still know how to use a dial caliper before it is over???? I have had cuemakers tell me they can't read a dial caliper, they must have digital.
Don't think I am kidding as some very good machinists have told me that they can't find any real machinists to work for them any more as everyone just learns to program and load CNC machines. Many can't cut threads or other simple machinist tasks. I know you can so don't take anything personal, but most of us knew how to build cues without so much automation at one time.
