Did you assemble the motor with charged neo?? Or did you charge the motor after assembly? Or did you use aluminum bottom adn top plates?

My guess is he did that charged.. Just from the N on the magnet.. Looks like they pulled a fiberglass cone too. I hope the bolts holding the motor together are aluminum and not steel.

bolts will be fine being stainless. if they were alum bolts they wouldnt hold squat. that cone heavy?
who ever machined that motor needs help. it's called a finish pass .010-.015 at high spindle speed(part that diameter,500-550rms) and low feed rate. then put some scotchbrite to it...

actually your speeds and feeds need to match up if you have too fast of a spindle speed and low feed rate you burn up your tooling, if it be a endmill or carbide insert. and yeah it does look a little rough. but overall very cool idea. i've been considering building some for fun if work ever slows down enough to free up the cnc mill.
p.s. pimpin i know you have had alot of exp with the pbx xtrm subs i have one with a chrome basket that a friend fried the coil on. know if i can recone it or where i could get parts for it? i've never done a recone but i want some exp and figured i could try it on that one !

conner in ur finish pass you want a high spindle speed and slow feed rate it will leave you with a nice finish and you wont burn up the insert taking off .015. you have to use the right insert for the material. that is all based of the degree of the tip of the insert. i do this 40hrs a week...
the problem with the pbx xtreams is the gap is realllly tight. what you have to to is pop the top plate throw it in a lathe and use a boring bar and take .050 out.
to pop the top plate. pour laqure in the 6 screw holes let sit, do this a couple times over a 3-4hr time frame. then get long 6mm bolts and keep tighting evenly and the top plate will come unglued. when putting back together make some shims for the new gap. put the bolts all the way threw the top plate 2" bolts work best. mix up some 1hr setting epoxy. drop the shims in and lower the bold evenly.
be VERY CAREFUL messing with a charged motor esp of that size you could break a finger or smash one really bad...

well u know if you feed the flux capacitor and drive upwards of 88mph that you can travel through time.
