Testing Pump

With a new fluid-o-tech one w/o bypass - with the flow restricting nozzle (single hole disc) and empty portafilter (two outlets):

approx. 460g/min.
remeasured 3 times, approx. 540 g/min

Remember Double shot = 60ml 20 seconds is too short, 30+ seconds is too long so you really need 180ml/min at pressure.

Grinder Mazzer Luigi MINI TIMER COFFEE GRINDER

Nut that holds burr carrier on is 13mm
Use 3 M4x40 machine screws in the burr carrier holes - finger tight then 1/2 turn each - round robbin to remove lower carrier. Gentle -if stuck get gear puller. One could tapper the end of the screw and grind a smooth and flat end to the screw - touch of grease..
There is a shear-pin that meshes with the bottom burr carrier - so they need to be aligned when re-assembling. A ink mark on the carrier and a second on the top of the shaft can help with alignment.
