That is seriously pretty!
Thank you for posting all the images.

Thanks for posting this mesmerizing video. Looks like it was shot in Space; the 'Coffee' equivalent of a Solar Flare or a Coronal Mass Ejection of the Sun.

Now back to Earth...

LS.,
After some time it's good to do a (small) update.
Due to the hydraulics of the Velox (continuous line/brew pressure on the boiler/pistonseals), a notorious familiar problem is rusted springs. So I worked on some small improvements. Firstly, I replaced the standard spring with stainless. Quite a journey to find one, but Brooks espresso machines helped me out. Secondly, I cut a standard W-seal in two, giving me two thin V-seals (thus double top sealing). --> problem solved.

Due to the replacement of the spring and others, my espresso came out awfully sour. I used a SCACE device to monitor the outgoing water temperature, and it was far to low. Therefore I squeezed the water inletvalve (less cold water entering the boiler) and incrementally adjusted the thermostate untill the outgoing water temperature reached the desired temprature (approx 195 F).

Great stuff....

Cheers, TY

Ingenious stuff, Ty!
How did you manage to cut the w-seal in two? (The skills of a surgeon!)

Well done!
How do shots compare now to other vintage levers that you have known and loved?

Cheers,
