Hey guys, new guy coming into the pointy end
Just had a question regarding advice on a rebuild. Last year I picked up coffee machine restoration as a side hobby to keep my sanity while grinding through schools monotiny.
Heres where I had questions. I recently picked up a La Cimbali M20 for a cheap price i believe and am doing a full rebuild of it (will post pictures when finished). Started with a complete disassemble and acid dipping (citric of course) and everything is going well. Currently waiting on gaskets and such to come in so i can reassemble. While waiting, I usually crawl along craigslist for good finds and stumbled upon another M20, this time it was a dosatron ;D. Perfect because I figured now I can keep the dosatron and sell the other. However when I picked it up, I saw that this one was in worse condition than the other one. So now, I figure ill take the best of both and build a frankenmonster and then rebuild the other and put back on craigslist for somebody else to enjoy. I was assured both were working perfectly before being pulled and looking at both, theyre built like tanks; theyll work :].
Although I do have a request for advice from more experienced people here. I believe one of them was built before the other since the groupheads are different. One has a direct feed from the supply into the HX, while the other has an additional "cooling" pipe. Knowing the importance of temp. stability of groups, which configuration is better? I have two pictures attached to this to help clarify.
As you can see, the first picture has a pipe going around the solenoid while the other doesnt. Any ideas as to which is better and why?
Thanks for all the help!
