somebody should show this to Alan Adler, because with this addition he could legitimately claim the AeroPress is an espresso machine, as he has always insited on labeling it.

Woah, I didn't notice that this thread got revived! I thought it was dead on the 30th.

This is awesome. :) Your video looks professionally produced and sounds like it too. Manual lever machines pretty much work on the same principal.
Do you plan on getting your machine remade into metal?
A few things which will help you...
I noticed you had a scale in the video.. if it measures down to 0.1 gram resolution, run with that. If not, you may want to consider a scale which has that resolution.
Measure your input dose. What are you aiming for now? I have no idea what an Aeropress needs, but start out with 16 grams. That's a typical double shot. Measure your extraction time. Aim for approximately 25 seconds, plus/minus 5 seconds. Measure your output. You appear to be aiming for a cup full. See if you can aim for roughly 32 grams. Plus/Minus 4 grams.
Tare the scale first on your dose and tare the cup second.
That may help you make your drinks a bit more consistent. Compare those results to your espresso machine using parameters as close as possible. (I noticed you had one in your video.)
Thanks for the input! We've been dosing at about 18 grams for a 30 gram yield, with pull times generally between 20 and 30 seconds. Consistency is difficult, to say the least! We cut out a lot of ugly measuring and stuff from the video, as we figured no one really wanted to see that. No plans to get it remade at the moment, but we're considering creating and releasing schematics for the public.

One major fault is that you loose the temp in the water way too quickly, the Areopress was never built to be a manual espresso machine, the plastic body, I would think, will not take that kind of abuse for long.
I guess if you were dying for shots, it is better than nothing but you have an espresso machine anyway so what really was the point?
Simply because we can! The stress on the plastic body certainly was a fear at first, but after a few pulls, we found that excess pressure was vented through the screw-on plastic cap, rather than through the sides of the aeropress. It's rarely used, as it's practicality is near zero. Additionally, some sink shots out of this thing are arguably not "better than nothing"! :)

Great ingenuity. Where there is a will there is a way. Maybe your friend can make a ceramic cloth slipover cylinder (to retain heat) to slip over the aeropress body after tamping the grounds. After that he can pour in the water and press.

He posts here sometimes, doesn't he? He'd probably shy away from this baby, seeing as there's no way the aeropress was designed with this sort of abuse in mind.
