I resurrected the old Pen Wizard,I have predudice in its frailty.The tramil or main support is awkward and not stiff and firmly held. I fitted a dust removing schute and a dedicated small vacuum. Using a Dremel with the holding mechanism is sus. I bought top quality drills all carbide from Europe.Locked the mandrel holder in position with locking plier. My own Pen faceting designed unit I have put aside ,hard to find quality end mills for wood.,controlling the three used axis is like a gymn workout and definitely not for the faint hearted. Just a phase balance and walking ulcered feet have been depressing,grabbed that black dog by the throat and shook it about (on the mend).Another beaut Peter. What mods did you have to make?
