Ndeipi
I attempted this. It took two or three evenings and maybe four charge cycles of the Makita. And it killed like five drill bits. The spindle is now out, as is the NDS cartridge bearing, but most of the BB has stayed put.

DS situation:
I could maybe nibble away at the remains of the NDS cup some more, though I've already troubled the frame's BB shell threads in one small area. It might give me a chance to knock out some more BB parts (hammering from DS side). But without a spindle I would just be drifting that 2mm black surface showing behind the shredded alu teeth.
I'm quite tempted to just dissolve the whole lot out with caustic soda but I would then need to repaint (which is a shame as the paint is quite cool). Does anyone know of a way to protect paintwork in a caustic bath? Like can I coat the whole area in silicone bathroom sealant or maybe heavy grease / vaseline? Peanut butter?
