Nij,

no problems by that - I buy another 1290 - I can afford that./smile/
Cpmpared to my "Hassle-Blades" Minolta Multi pro etc etc it's a minor 
cost. 
It's expensive and it's fun - LET's have fun! 

I bought the tubes from MIS - they are cheap as other real stuff 
costs - I have also learnt that every system like this are using this 
tubeset - none of them have the more expensive ones.

For the wentholes - I have a simple but irriytating solution I have 
made plastic cones (Not Cones plastic /smile/) that I place in this 
holes when not in use - but they are not "automatic" - I can forget 
them.
Erlier I used a plastic bag with a damp piece of cloth to get 100% 
rel humidity taped it - and it works as well but look rediculous when 
custumers came for looking at my gear....aren't we some sort of 
crazy...but we photographers are as well some sort of "artists" ... 
and dont like that - ahhh plastic bags.hmm....

Have just made an investigation by friends (hospital engineer and 
designer for apperatures, also been at 
http://nalgenelab.nalgenunc.com/products/catalog/category.asp?
catId=173

The Nalgene place to have a look - it look promising.

Words to use here : The common tubes are permeable letting fluid out 
and avaporate AND absorbtic letting air in (It's a two way 
interference here) (I don't know air may corrogate some chemicals and 
gibving them other colors, changing the chemical formulas etc etc.


What I need now for RR (Rolls Roys) is what I have learnt are tubes 
made of "Tetrafluoroethelene" that is both absorbtion and 
permationrestistent. I now Nalgen have them - but are expensive - but 
I dont care!
However, are they elastic enought to give it an easy go or do I have 
to heat them to have the right bend and mobility?

They also do have selflocking connections - that could make it easy to
maintenace the tubes now and then!

It is to remember that the tubes has a far greater relative area to 
the air than the bottles - so for me it's obvious (also by my 
incedent) that this is of great importance to evaluate the systems.
Ok this was the first indikation with MIS "double black" that has a 
lot of carbonparticles in it - however in the long term every tube is 
affected and build up - to stiff grease like things - that can't be 
good at all. Investigated the other tubes as well - and they also 
have grease - but not that much! 

So when printing - are You happy wityh the blacks - if not I know 
where it's hidden./call me and I'll tell You - smile/

Du Pont have alo such tubes - but not on the web! And I'm certain 
that industri fellows can help me to further deliverants!   

I don't care if the tubes are single - it's easy to connect them with
some sort of silicone every 5 cm or so or why not tape them with 
different colors - making it look like cobras /smile/ - have a 
suggestion for that one?

The hunt goes on!

Help appreciated! For sure!


Thanks Ninj!
