I wonder what pressure we will see on our pulls with this apparatus in place. I will bet some of us are pulling at 20 bars and others at 6.
Maybe this machine should do a tour, to get a larger sampling of lever practises. Or as a training tool. However I am excited to get my brass beauty back to Montreal for a while, Of course only after all our Alchemist has exhausted all testing and has had a thoroughly good time with it.
Now we have to invent a sieve for measuring the varying degrees of grind.
Brew pressure varies, but it would take Schwarzenegerrian strength to reach 20 bars on a ~50mm piston with a lever of typical length and the typical distance between pins. I suspect the o-rings would pop well before that point.
