For those who like numbers and find scales a help in chasing good espresso.
I find scales are a great help in dialling in my grinder and playing with extraction but I was sick of trying to dry them off after the relief valve flooded everything at the end of a shot. I then learnt about a nifty gadget that allows you to sit the scales BELOW the tray and supports the cup/s ABOVE the tray. But as it was more than a hundred dollars I thought I would see what I could do myself. Photos are of a prototype but if I am lazy it might last some time before I go for an improved Mk II.
All works extremely well. Only change might be to make the cup platform a bit deeper as the cups only just reach the PF outlets. You also have to be sure nothing is fouling during a shot so as to not interfere with the measurement.
