What does the silvering help with ?
1 Like
the silvering helps keep in thermal radiation, youll notice on some of them, the bottom vacuum jacket is only silvered, this is to create a delta between the vapor tube and the condensate collector up top. the silver part is always hotter than the unsilvered part.

So this makes for a faster head or?
I just hope it’s not made with mercury or any other heavy metalz like Lanphan did…

Looks nice, too bad the condenser joint is 24/40. That strangles speed plus everyone uses 29/42 joints, pretty much.
@david If you are making these I’d advise you to change that joint to 29/42. If you are able to please dm me so we can discuss things.

@david will custom make it with any joint you want. I had my whole 2l wide bore done with 29/42 joints at no addition costs.
I’ve heard people here going as big as 45/50 on bigger heads.

Hmmmm, i kinda want 34/45 from bf joint to condenser joint, but the joints after that connection would still be 29/42, so that might make that idea useless. Or maybe not. Hmmmm.
How much david, for the 10l?
That’s pretty close to the diameter of a KF-25 fitting so that would be bad ass…when’s kf-40 going to become the standard in vacuum fittings lol
