What espresso machine are you currently restoring.

Like many I find the more I work with a particular machine the better I get at learning it's idiosyncrasies. Decided to take on another 3rd gen Faemina Faemina. Found a good technique using steel wool and a soft wire brush drill attachment to be an effective way to clean and polish deep within the group and boiler.
Here are some pictures in progress.
Going to have to get creative in order to replace these brittle screw on end caps. They go on the PF, lever and boiler cap.

Between order and chaos there is espresso.

Machine them out of Delrin (Acetal) and thread a central hole for the stud to screw into.

Good idea, seems like I'll have to find a local machinist who works with Delrin.

Any of the small metal lathes will machine it just fine as it is easy to machine without making stringers.

What wire brush are you using? I was tempted for a brass brush on copper but I'm fearful that might be too aggressive for copper.redbone wrote:Like many I find the more I work with a particular machine the better I get at learning it's idiosyncrasies.

I'm starting to dig into the Cimbali M20 two group I posted about last week. The groups are a disaster, but I find the disassembly work satisfying. So far only one broken bolt and it left 1/2" of protruding stud so I'm confident I can get it out with heat and patience.
The small inner springs are fused into the top of the piston head, and I can't determine if the piston rods are salvageable until I get those out. I'll take the group castings, pistons and piston rods to get media blasted once I finally get it all apart.
Luckily the groups are far and away the worst part. The boiler is stainless and although it has a good amount of scale, it's intact. Electricals are solid. Everything else is pretty routine in terms of a rebuild - needs new gaskets and seals throughout and a thorough cleaning. I want to see what I really have with the groups before I spend a bunch of time cleaning the rest.
