What specific difference do you see in the foam when you block two of the holes, less frothy top?

Posted January 28, 2013 link

When I froth with all holes open, with wand a little angled, it seems that in keeping the highest of the three holes at what I believe is the right level, the other two are maybe too low and are only heating up the milk. The result is little microfoam before milk is too hot.  When I plug up two of the holes, I'm able to keep the one hole at optimal level, and get great microfoam.  I'm steaming around 5 ounces of 2% milk in a 12 ounce RW pitcher.  Maybe I need to keep the wand more vertical such that all three holes are closer to an optimal level contributing to frothing?

Could be, but if one hole works for you, why mess with it?

Good point. If I could find a good way to semipermanently plug them up, assuming I'm unable to refine my technique with 3 holes. Currently I've just been experimenting using toothpick tips, which is obviously not ideal.

Question for the BDB owners - I see the BDB listed as a 1700 watt machine - and know that Dual Boilers can really push a lot of 15A / 120V circuits out there...

I guess I could use Ohm's Law :-) to figure out amperage draw - but even still, amperage and wattage ratings are typically given as "Peak" numbers and don't depict what the machine will draw in a steady state.

So the question is - how are most folks finding the BDB working with their typical 120V / 15A circuits?  Do they need a dedicated outlet for the BDB?

Sorry if this question is answered somewhere in this 147 page thread, but I guess that's one of the drawbacks of 147 page threads!

A few ideas for you.

For the semi-permanent version with the toothpicks: unscrew the wand tip and insert them from the inside. Backpressure should keep them in place, but like you said - not ideal (from a sanitary perspecitve) but at least you could worry less about one ending up in the milk...

Maybe you could experiment with the final rotated location of the holes. There is a rubber gasket between the tip and the wand so there is some leeway for the end orientation. Bring the wand to your normally desired angle and turn until 2 of the three would be level with the milk surface. You've just doubled your frothing power and reduced the speed of heating since only 1 hole is pointed directly into the milk...

Next it would be up to someone to determine if the diameter and thread pitch were compatible with other steam tips. I imagine they are.


Cheers,

Bryan

I would either find a new one hole replacement or just ditch the tooth picks and go all the way.

From my recollection of the manual (noted revision from the online .pdf) it has a statement about the Austrailian requirements for a 20min duty-cycle for electronics that consume more than 1500 watts. It's not likely that that kind of draw is continuous for more than a couple minutes, max.

I'll bet Richard has a Kill-A-Watt handy. Maybe he could speak to this?

on "other" leading branded expensive italian espresso machines, some folks buy "acorn" nuts from places like grainger and mcmaster carr, and drill their own holes.  acorn nuts (the ones i've seen) are not solid all the way through, so drilling them would not be a hellish process of dulling out sharp bits and lots of slow going and patience.  i do NOT know the thread pitch of the BDB tip but i'll bet my dollar to your dime, it's metric.

an example of an acorn nut:

Thanks for the ideas on the steam wand tip.  Rotating it would probably help, like you said, Bryan.  That JB weld would work. Is that food safe?  An acorn nut seems like a good idea, however I like the smooth contour of the current tip.  I wonder if I could drive in a segment of a sewing/push pin?  It would be nicer if there's a compatible single hole tip that I could try.

I ran my BDB while connected to a Kill a Watt.  The highest reading I saw was around 1520W, and that just briefly (~10 seconds) while drawing a double and steaming simultaneously.  When just making an espresso, it was transcuently a little less than 1000W.  I haven't yet tried multiple shots in sequence.  My BDB hasn't tripped it's 15A circuit yet, but the only other thing on that circuit is a cordless phone which surely doesn't draw much power.
