Been getting a lot of personal messages on here about mods on Kitchenaid Espresso machines. So far seems most people aren't reading my replies or aren't marking them read. Decided to make it a bit more public and possibly help more people.

Mods:
Changed shower screen holder from stock aluminum to brass - better thermal mass (massively reduced the temp swing in shots to almost negligible if I let it warm up about 20 minutes or so)
Dripless Commercial OPV - No leaks, adjustable, doesn't wander
IMS Competition Screen - better/more even extraction
IMS Competition Basket - better/more even extraction
Caffewerks Silicone Portafilter Gasket - better gasket/easier to wipe down
Thicker Bottomless Portafilter - Judging shots/possibly better thermal mass
Rancilio Silvia V3 Steam wand - better traditional steaming
Modding the steam wand to burn-less (lined with Teflon tubing)- Got tired of having to scrub down the steam wand if I didn't clean the split second I took the wand out of the milk
Updated thermostat on steam boiler from 145C to 155C - Better pressure and mitigated variation on quality of steam
Replaced stock steamer boiler gaskets to silicone - required with the extra heat/pressure otherwise steamer boiler might leak.
Changed the rubber feet from ¼ inch to 1 inch - Needed the extra height for steaming since the replacement want was longer plus it helps evaporation of any moisture under the machine from refilling the tank etc.


Wand:
The Rancillo V3 required an adapter and a trip to the machine shop to open up the adapter to let the spring and teflon seat for the ball joint move freely. Also I recommend taking it to burnless since you'll be in there. See guide here: DIY Rancilio Silvia V3 wand conversion to "burnless"

OPV setup below: OPV brass adapter pieces were bought from Lowes but required some modification at a local machine shop for proper fitting.


Feet: Feet I got from Amazon, but required washers and other hardware to get the fitting right from the local hardware store.
