A friend and I created a contraption to use an aeropress as a true espresso machine: 9 bars pressure, a puck, and a metal filter. Check it out! I'll answer any questions that anyone has. As far as I know, this hasn't been done before.

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.)
Good luck! Let us know if that helps.

That's awesome! After watching the video, I was thinking, "Man, those shots must be black and white back to back," but then I read the rest, and obviously that's the case. Still an awesome contraption. Probably the most inexpensive espresso machine to date.

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?

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.
