I'll dismantle (and often reassemble ;-)) just about anything. As for motors, I had to strip the punch motor in the PC04 today. I fitted the step-down transformer so I could run said unit, then found the motor was solid. The bearing oil had turned to something rembling tar. I will try to get photos of that uploaded soon. The only motors I am a bit careful with dismantling are permanent magnet DC ones. The field can demagnetise if you don't fit a 'keeper'. But I will do those when I have to. See the photos in my VAX11/730 album on the same site for the insides of the TS05 motor. As for the cabinet fan, the old bearings were rusted solid, but the windings were perfect, and a pair of ball races are a lot cheaper than the entire fan. Strangly said bearings were metric dimensions (which made them easier to get for me). -tony > > Nice photos, indeed. > > paul >
