Mark’s Machine has arrived, after a long time of pondering, false starts and trial and error. It is big (they said 33 kg, in fact it was over 60)
For the coffee geeks amongst you:
Futurmat, Ariete model, two group, Solenoid E61 group head (9lb of brass each), 11 Litre boiler.
It is over 10 Amps, which means re-wiring a plug in the kitchen. 2735 Watts. Lots of fun.
