And then I've put on my headset magnifier and have flung myself with desperate courage into the Barber Pole Action again.

Here is the spiral after 10 rings,

after 0 rings,

after 40 rings,

as well as after 50 rings.

And here the goal is reached and I could finally stop.

Here I have threaded the first of the 12 Ice Ramps (R20),

whose position I will mark next and then mask them.

Even though I can see it, I still find it hard to believe that this was possible to achieve. It is fantastic. Well done Manfred, your eyes and hands deserve a treat after all that!

Regards and take care

That is precision work beyond belief.

Thanks Kevin for your nice comment,

sometimes I am amazed at myself ...

but nothing is impossible, if one firmly believes one can do it.

Hello everybody

meanwhile I have decided not to flour the two ET Tanks separately, but to glue them together with the Intertank beforehand, which should make handling easier.

And for the Flour application I have in mind a horizontal mount similar to the Test rotisserie,

for this I'm going to insert the aluminum rod that was already in use through the front Nose Cone opening, which reaches to the Aft Dome. This rod then is clamped in a side holder so that I can turn the tank around its axis during spray gluing and flouring, whereby I will first flour the LH2 Tank, and then the LO2 Tank.

Before gluing of the three ET parts, I had to mark the exact position of the 12 Ice Ramps (R20) on the LO2 Tank in order to be able to cut out and mask their contact sites, taking the exact alignment of the GO2 Press. Line up to the Nose Cone had to pay attention, which was not so easy to do.

Afterwards I've marked the position of the Ice Ramps with the help of the Newware template,

and then were cut them out.

Then I had noticed for a longer time that the Newware Ice Ramps are rectangular (3 mm x 3,7 mm), and not square like the original Ramps.

These have the dimensions 1,5' x 1,5', which corresponds to 3 mm x 3 mm in 1/144 scale, which is why I will adjust the ramps accordingly, what has already happened with the front ramp.

Then I've yet masked the contact areas and the front part of the LO2 PAL Ramp.

Thereby however, I had not considered that the PAL Ramp is right next to the Cable Tray (0,5 mm x 0,75 mm) and therefore has to be a little wider,

which I've corrected after I had put on the channel for better orientation.

That's it again for the moment. Thanks for watching and have a great Sunday.
