If room could be found for it would this alleviate steaming problems for
single boiler machines?

The problem with this is that most steam toys don't have adjustable
steam valves. some don't even have a power switch independent of the
brew/steam switch. nothing like watching your "cappuccino maker" pee
all over the counter to let you know it's ALMOST ready. i opted for
this:
snipurl.com/cheapdoubleboiler
and it works like a charm. the best kind is the Benjamin & Medwin
(though i think Bellman is exactly the same) brand because it has a
longer steam wand than the one pictured (i bought a B&M stovetop model
for parts and swapped the wand). the boiler on this thing is HUGE and
made of stainless steel (most cheap steam toys have aluminum boilers)
and can steam for ever and ever w/ no noticeable drop in pressure till
you run out of water. it's t-stat driven (w/ indicator light,
dedicated power switch, brew and steam are controlled by independent
adjustible valves, not switches) and has a safety valve on the back
(pretty sure it's not the one-time deal like Bialettis have, though
it's never tripped yet and can be replaced). i think these can be had
for about $75 new, though i'd just check eBay. i'd like to find a way
to pump feed this instead of unscrewing the top to fill (though one
fill-about half full really- can steam cappas galore. despite the
added counter space, beats the crap out of waiting to steam after
pulling shots or vice-versa.

i'm actually working on this right now (creating a new body for the
guts of my PID'd Carezza plus the extra steam boiler-lots of aluminum
drop lying around from my days in the sign biz).

Howdy David!
Having this capability would be an improvement for Gaggia & Rancilio home
machines equipped with solenoid activated 3-way valves. With the 3-way valve
shot after shot can be pulled with occasional pauses for the boiler to catch
up. This *extra boiler* would add concurrent steaming to the capabilities of
these machines. Sounds like simple solutions to vexing problems home
baristas often complain about; only being able to steam small amounts of
milk without having to refill the boiler & bring it back to temp & having to
wait for cooldown after steaming.

The only issues to work out would be finding room for the TB, arranging a
pressurized water source, wiring the TB, routing the tubes. Doesn't seem too
far fetched to me. In fact, I'm going to put this on my list of things to
look into more.

Two things; 1) I'm assuming that these are either on or off with no
thermostat, 2) would a gicleur (?) be necessary?

BTW, if you really want to kludge something useful with this steamer, why
not find a way to connect it to a dot-matrix printer to print latte art on
the coffee? Something like this toast version:

As I see it, to make espresso one requires a machine that will deliver the
proper tempriture water at the proper pressure.

A secondary issue is how to get steam to process the milk.

For home use this seems to be a really simple problem to solve. If you
apply heat to water you are gonna get steam.

Why not just spend $10 at a thrift store on a pressure cooker, add a valve
and a steam wand? After all most homes have a working stove.

Another alternative might be to spend the same $10 at the thrift store on a
steam toy and use that to process the milk. These seem to be rather usless
at making the coffee, but should work just fine for making steam in any
quantity you would need for the milk part of the recipe.

The problem with trying to coax one tank of hot water to use for coffee and
to make steam for milk is alwasy going to give you grief because the
tempriture you need for the steam is greater than the tempriture for the
coffee. you are always going to comprimise with a time factor as you cool
the too hot of water to make the coffee, or to add heat to get up the steam.

Stuffing a different appliance into an existing one is also going to give
you grief to find space and you are likely to find problems with the
transfer of heat from the steam side to the delicate temp control of the
water for the coffee.

About the time I had mastered getting the toothpaste back in the tube, then
they come up with this striped stuff.
