Exactly, I'd like a base for Ithaka-GGTS like the one for Thilemahos-Esterigon.
Fact is, I don't know how the hybrid base for Tilemahos-Esterigon is made... are there any pictures?
But I imagine it's made in just 1 piece plus the AD ring, Right?
The part I'm thinking for Ithaka-GGTS must be in 2 pieces plus the AD ring, as it has female threads on bottom (to fit the male on the sleeve ext.) so the AD ring is "prisoner" between the 2 pieces...
So, we actually need only 1 new piece: the standard GG Ithaka base is OK for the second.
Recapping, the new piece could be something like the upper part of Ithaka 510 base, maybe with the new AD ring for JGG (or maybe with the classic threaded ring?), but with a different bottom side: in place of the 510 connector, the female threads to fit the sleeve ext.
Mmmm. I realize I'm speaking about a compact version of GGTS Connector-CT...
But I'd say this way we can make the GGTS 12-13 mm. shorter. (Good for VIR
)
