Hi Roel

Firest of, nice to see that someone tires to build a station!

I did not used PVC sheets. The hobby glass is made of Polystyrol which
is really easy to weld and bend with the hot air gun. I do agree
though that creating the tanks is from the point of view of the
mechanical aspects a more difficult part. I also "wasted" about 3
tanks until I had it going.

Another option might be to glue the tanks instead of welding. There is
a guy from gemany currently building the station and he decided to go
this route. He posted a picture of the tanks in a german web based
electronics forum and since the thread is a) in german and b) not
directly linkeable I put the picture of the forum up to my website so
as you can take a look.

Aparently you solved the problem with the vacum unit you mention.
Interesting, do you have a picture of it?
