Thanks

So it was 20.3kg for 7.4 bar somewhere at the begining of extraction (0:23 of the video) if I see correctly. And 22.3 kg for 9bar several seconds later. About 40-50% more force for the same pressure than I measured back then. However, I was holding the lever at the very end, maybe that's one of the reasons I measured less force needed, in addition of not having very good scale

Can you make one more video where we can see the angle of the lever and the force at the same time and post just a photo of the diagram at the end?

Holiday first :-).

Today we had another toy to play with :-)

Incidentally had a closer look at my piston. Should I be worried and change?

That is disturbing. Is it caused by the angle of the piston when you crank down on the lever?

Did you use any chemicals on it or boil it before use?

Sheer plus some kind of weakening....

I never use anything else than water, and there's no treason to boil the plastic piston.

I thought the O-Ring should prevent the piston from excessive rub in the cylinder.

Have been brewing ca. 2 coffees per day since beginning of last november.

So at the end, correcting the angle of PF base with a shim as I mentioned wasn't a bad idea ...
Ayway, I suppose this shouldn't affect functionality.

I'm not worried about functionality, more about whether I'll risk scratching the cylinder with this.

I doubt it

I think someone in an early batch of flairs said something wasn't completely round and had to be replaced so the pistons travelled smoothly. Not sure if that applies to you.

I think no danger of scratching the steel. However, loose pieces of plastics could damage the seal, but spare seals are not expensive
