Stuff Michael Meeks is doing

Up earlyish; breakfast, off to NCC. As if my some miracle managed to persuade E. that her Father really was coming back if she was left in the creche, and that she could play happily alone; listened to the next installment of James.
Back for lunch, slugged in the afternoon, while babes watched a movie; then helped H. and N. learn chess piece moves for bishops and rooks (on top of the previously learned knights) while M. built things out of Jenga bricks.
Packed the babes to bed; nearly at the end of Lord of the Rings with Hannah. Back to the reprap; tried to get the (now working) extruder driver to extrude - PLA (it seems) requires rather more force to get it out; played with temperature but, apparently even a (handy) elephant sitting on it is insufficient to extrude it. Hmm, suspicious of the over-long brass barrel before the insulator in this nozzle. Sermon on Daniel from the archives to consider and write notes on.
Couldn't sleep, so spent a while affixing an aluminium mounting for the extruder, so two elephants can be applied without forcing the extruder nozzle itself out; still no joy. Perhaps best to go back to ABS for a bit. Bed late.
