Dieseld - Thank you for the advice. The Breville has the option of dialing in the grind by adjusting the burrs internally - in addition to the external dial. I haven't had to do that since I am only grinding for pour over and french press coffee at this point.Quote:

The gasket on my old Solar-Sturgis vacuum pot has given up the ghost, Now to figure out how to make one, anybody have any tips.

If he hasn't yet, contact Geezer - a master at repair and rejuvenation of all things not easily found.
Done similar. Get some artist clay. Olive oil, NO petrochemical!!Quote:

Above all no hydrocarbons around RTV. Not even for going off.
MikeB52 has hands on experience since I have. Have fun!
Thank you Geezer, That vacuum pot is functioning again thanks to your advice. I repaired the old seal with a bit of sisal twine and some rtv, not the classiest repair but fully functional thanks.
Some day in the future I will cast a whole new seal, but for not it is working and I am happy.
Hi friends....I just happened upon this thread and I am very happy to say I will be reading this at night before going to sleep instead of reading a book....I am a coffee lover and I really enjoy all your different opinions....this is my little espresso type coffee maker that I use for a quick zap pick me up...I use Melita espresso beans , grind them and pop them in this mini marvel.....thought I’d share ....Kathy.https://youtu.be/c_-3mdZuu2k
""I stopped to think..what about a thin coat of RTV around the inside wall of the seal doughnut???Quote:

That is basically what I did, I built the ribs back up with rtv soaked sisal/jute then over coated with a thin layer. It is working well so far.Quote:

Grant wired his Dogé Conico to a timer control box set to yield about 19 grams — just press the green for go button!

Progressive preinfusion indicator button atop right extends outward as brewing preinfusion begins, peaking at around 1” out and equal to full line pressure at the grouphead (so, “mildly” from 0 atm to say 3.0 atm in ~ 10-12s).
Lowering the notched drive handle about halfway down, then moving the whole handle laterally leftward, places its notch over the a hook for preinfusion. Or, you simply hold the handle halfway down if you like.
Extending the handle fully downward, the commercial-duty rotary pump (housed in his basement thanks to one serious OEM extension kit he bought; mine was under sink) kicks on to bring group pressure immediately to 9.0 atm (typical, not gospel) until brewing cycle has completed. Lever can be locked under the preinfusion hook or held until barista finishes pulling the shot.
The levering mechanism Kees engineered is phenomenally brilliant using 2 plunger-actuated switches (all steel w/ steel contact wheels, no plastique, no sirree!) for the brewing features. Will need to take an interior right-side shot someday to show that engineering off.

Bloody hell. That's some machine and setup!
