What's going on around the piston though?

That looks like a temperature strip, so I'm guessing it's a preheat chamber of some sort for the piston?

So I bent my 2+ year old screen yesterday : (
Still works like a champ : )

OEHandgrinders has replacement screens with the silicon pin and replacement silicon pins. Still haven't managed to bend my original Kickstarter screen pin.

I think most ppl bend their pins on the second stroke to expel any unused water from the chamber...so I've dropped that step. At the end of the shot I unhook the portafilter with chamber still full of unused water and I carefully tip it out in the sink. I figure this cuts down wear on the seal by half as well as reduce the chance for a bent pin.

I always let the arms fall on their own after the shot - I arrest it when the dose hits about 5-8mm below the cut line on a wee Picardy tumbler. My wife always likes to save the aftershot, she often bottles it in a corked San Pellegrino water bottle and drinks it at work : )
PS - she cuts it off before the foam begins

I put the tamper in the arm when I'm done with the shot and let the weight of the tamper pull the arms down while I enjoy the shot.

I clearly have more time on my hands, plus I also use the mitts.
