Subject: Custom made steam wand?
 

Ever since i got my 1997 cimbali junior I've been having trouble with getting consistent microfoam. I only steam very small amounts of milk at a time and I think part of the problem is that the steam wand doesn't leave much room to position the pitcher when the wand is nearly upright. I think if it was out from the machine a couple more inches id have much more room to put the pitcher and wand exactly where i wanted.

Im wandering if i could make my own custom wand out of brass tubing? I currently use a marzocco steam wand that has the top ball joint soldered on so i thought i could take that off and put it on to a new custom bent brass tube and just tap the end with the thread needed for the marzocco tip?

Would there be any issues using brass instead of stainless steel? I presume i would need to use a silver solder to reattach the top ball joint, even tho its not under pressure constantly? Finally, does anyone know what thread marzocco uses for their steam tips? If its some rare thread type then that could be my plan finished before I even start.

Thanks!

Iirc, some brass alloys have lead...so you need to make sure yours doesn't before you fashion it for your machine.

Copper should be OK though and you should be able to find it very easily, combine that with lead free solder for plumbing and just about any form should be possible.

The original steam wand was actually chrome plated copper. The poor machine had a very hard life being abused in a cafe before i bought it so most of the chrome was missing. Given what i found in the bottom of the portafilter, a bit of chrome wasn't the worst thing their customers were consuming with their drinks!

I had sort of glossed over copper for some reason but your right that it would be much easier. I did find a local tube bending company that does "food grade" stainless steel but it would be good to be able to play with the shape myself first before going down that route.

Thanks for the suggestion.
