Dear Pat and Alessandro,

Thank you so much for your prompt replies.

I aprreciate Pat's work. However, I rather like to keep the 
straight cylinder to 1530 mm and avoid split franges for 
simplicity. With this simplified scheme, all harnesses and 
tapes are ending at Z=765 mm, making easier for other people 
(our children?) to understand.

I like this proposal as another simplification. I propose 
11mm instead of 12mm, leaving 1mm gap so that CoolingEnd is 
to be identified as another object. At the same time I 
extended the CoolingEnd to Z=765mm and also extended the 
Cooling pipes touching to CoolingEnd (otherwise our children 
wonder why they are not touching). 

Based on these proposal, I updated the volume table and 
corresponding drawings (with _v2) in the web page of
  http://atlas.kek.jp/si-soft/geometry.html

Hope these are acceptable to all of you.

best regards,

Taka
