After reading the posts in this thread & the "Lever Machine Smackdown" I started trying a few changes. Had a new base to start on this morning after yesterdays 6 pull morning. Settled on a grind level set at ~2 full notches (MazzerMini) finer than for the Elektra Micro Casa a Leva (MCaL). The lighter tamp (~#15) works better on the Ponte Vecchio Lusso (PVL). This may be disturbing to some of you, but I fill the basket by flipping the doser lever while the grinder is running and lightly tap the portafilter on the grinder portafilter holder to "distribute" the coffee & to breakup and chunkers. I also overfill. There is a mini volcano/mtn of coffee. Leveling is done with a chopstick sweeping a level surface. Leveling tamp, then the lighter tamp. ~1/2cm of filter basket above the grind. Following Greg's recommendation I tried and like the shorter preinfusion period (2-4sec) letting the boiler pressure infuse the puck. What has worked for me regarding the quality of the espresso that I prefer from this machine has been to release the lever until ~3/4 way to horizontal, then gently pull the lever back down and release. The shots are short in volume. Including crema ~1.5 cm below the rim of an Illy espresso cup. For people that prefer the clarity of a good MCaL pull this may not be your machine. If a heavier thicker crema is your goal the PVL may be the better choice. MCaL for espresso. PVL for cappuccino, a heavier espresso or when the need arises to pull multiple drinks.
A real factor that needs to be considered is initial cost. If you look at the current prices for the PVL single group vs. the MCaL, the PVL is a bargain. The price difference will allow you to consider the purchase of a real nice grinder if needed. I know to compare the two considering looks & build are unfair. But if you need a lever machine or would like to get into levers and have a budget the PVL should be strongly considered.
I insulated most of the boiler with a double layer of ThermoGuard FR. Pstat, heat element side is bare. There is enough clearance except the bottom of the boiler to double layer. Purchased the material from
http://www.AutoBarn.com ~$16USD + shipping gets you 8 sq ft. The heating element now cycles on ~6 minutes.
