 I bought this, for fun and out of curiosity: https://www.crossroast.be/product/ims-big-bang-filter-b702tfh21-5bb/ The Gesha beans that I currently use needed to be ground a LOT finer for this basket than I did fpor the 17g La Marzocco Strada basket (which I filled with 18g). 15g in the Big Bang basket fits well (larger dose tends to bump into the shower screen). 30g out in about 30s, reasonably good flow with some 'islands' of holes staying 'dry' for a couple of seconds even after the rest of the basket has a good flow going on, then all flows well. I did clean the basket in cafiza before using so as to be sure the holes are all open and clean. The special bean, light-medium roast gets a spicy element that it did not have in the Strada basket. Extracted on the LONDINIUM LR24, pre-infusion pressure set to 5.2bar

The Londinium LR24 lever gradually became a little harder to pull, feeling as if the spring was getting stronger (which obviously it didn't).  I pulled out the lever & piston and put it aside for a minute. Next I sprayed the inside of the bore with HG stainless steel cleaner. It created a skin of foam on the bore.  I took a clean micro fiber cloth to firmly wipe all the foam off. Then I took a new micro fiber cloth, made it wet with water and rinsed the bore clean of the HG stuff And repeated with another new microfiber cloth and water. Momentarily switched the machine ON to flush plenty water from the sleeve in case any cleaning agent had made it through the little holes. Rinsed the piston and re-inserted and fastened it and the lever into the group. Result: smooth operation! see also https://londiniumespresso.com/store/accessories?product_id=69 What is the worst part of owning a lever machine?
