I suppose I'll have to see the pics to visualize it.  My aroma comes in on thursday and I'll probably order the steam wand friday. I think once I start the process it will make sense.  Im interested to see what became of Steve's.

Posted March 16, 2010 link

Hi, I'm still here, it's good to have another mind working on this.

I'm still trying to decide what I want to do.  To visualize what Dave & MaryAnn are saying about cutting the side of the machine, look at the pictures I posted earlier of the two wands side-by-side.  The bottom of the Saeco case is marked and you can see how much shorted the Silvia wand is then the Saeco.  It's shorter than the Saeco case.  But if you cut an opening in the side of the case, it can protrude out of that opening.  This would and does work fine, use the Saeco nut with a couple o-rings like they said.  My problem is that I really don't want to cut a hole in the side of the case.  So in the meantime I'm thinking.  Perhaps cutting the two and brazing them together, Saeco at the top and Silvia brazed to the bottom.  But I understand that the heat of brazing can cause stainless to loose it's corrosion resistance.  I don't want the wand to rust on the inside.

I've also thought about mechanically joining them with a threaded SS coupler.  Cut and thread the two halves and screw them together using the coupler.  Maybe far fetched?  I'll keep you posted.

I've got an idea. Perhaps one of these could work:

La Pavoni Steam Wand Extension

This would effectively lengthen the first part of the wand before the bend, and then you could use the stock opening and not cut a hole in the side of the machine.

From what I gather, the standard steam wand thread size is 3/8" BSP (British Standard Pipe thread, not sure if it's parallel or tapered though). You might be able to use a 3/8" coupler and then a 3/8" nipple to lower the connection as well, although that option may take the connection TOO low.

I've got a Saeco Aroma too, perhaps one day I'll try this. PID is the next mod though...

This is what my idea is: cut the Silvia and Aroma steam wands to the needed lengths, thread the ends and join them with a stainless steel coupler as pictured.  They're made of food grade stainless and are in US 1/4" x 28 fine thread.  They are also available in a smooth style rather than the "nut" configuration.

I'm planning to perform this mod as well. Thanks to all who contributed to this thread for the helpful measurements, pictures, and info. I had a few comments on proposed methods:

An extension would be ideal, but it seems that there is too little room between the top of the wand and side of the boiler (less than 1/4") for such a connection.

Refer to knuf's image on the bottom of page 1 to view the proximity of the lip of the boiler to the steam wand pipe.

The only way an extension might work is if it were 1 inch or less in length (even then the hex screw top of the steam wand might cause fitting issues).

Cutting and threading the two pipes, Steve's idea, seems to be the best proposed so far. I have a few questions about this idea...

Any particular reason you opted for the standard Silvia wand as opposed to the V3 one? How would you thread the ends of the piping? Where did you find the pictured couplers?

Thanks again

Actually, if I were to do it again today, I might try V3!!  I think it is a great looking wand!  I wonder if part of the reasoning is that it may be yet untested and is it also much more expensive?  I think I got my V1 used for about 15 dollars.  

Maybe this vid will shed light on whether it is a viable option, which I imagine it is:
Click Here (www.youtube.com)

Also, I wanted to comment that one of the benefits of the Silvia wand being shorter and coming out of the side of the machine is that it gives more clearance for steaming.  I wonder though, have you figured a way to keep it articulating when it comes out the bottom of the machine?  That would be pretty neat, especially with a V3.  

OT slightly, but is the V3 just a cool touch or is it actually a commercially sized wand?

Hey Mummas, etc...

I did the V3 mod you linked to on my Silvia, but it requires replacing the entire steam valve, wand, knob, etc...  The V3 wand is definitely NOT cool touch (ouch), just looks more commercial stylie and for whatever reason pumps out better steam than the original.  I don't think the wand itself would fit your machines as it's a much thicker tube with a completely different (articulating vs just rotating) mounting interface.

Edit: I had not seen carabelli's post when I wrote the following. Consider the next paragraph "additional comments"

I think [Carabelli's correct] that the articulating wand requires a certain mechanism only available in the steam valve body of the Rancilio Silvia V3-- otherwise why wouldn't they install the pipe only? Since the valve body in the aroma is different from that of the silvia (the boiler pipe is on the side of the Aroma's valve; it's on the back of the Silvia's), some sort of plumping would be necessary to make the install. And at nearly $70 (jlhufford) for the assembly "kit" a V3 wand simply makes such a mod too pricey (for a student like me).

To go back to Steve's idea, and refer to my earlier question, it seems that a threading tap and properly sized die could be used to thread the ends of both the Silvia and Aroma's steam pipes. This would probably require filling the pipe opening with something to keep it from narrowing while carving the threads. This video demonstrates the use of a threading die (around the 40 sec mark): http://www.youtube.com/watch?v=x-Q34j0NceE . One might be able to find such a tools (and a die small enough; i'm unsure of sizing) somewhere on this page: click here (Page 2 has smaller dies and a die handle that might work).

Saeco Aroma & Silvia Steam Wand - Idea #1
Cut the wands to the desired lengths.  Braze/weld the two wands together as shown.  Brazing or welding stainless is done regularly but needs to be done by an expert welder

Saeco Aroma & Silvia Steam Wand - Idea #2
Cut the wands to the desired lengths.  Thread both cut ends with a 1/4 x 28 threading die, external threads.  Join the two ends with a 1/4 x 28 internally threaded food grade stainless steel coupler.
