Dear all
So to finish off stage 3 I first needed to amend some of the pipe parts from stage 4 to made a LH2 feed on the thrust structure of stage 3. For this I used one long and one short pipe piece and joined them as shown (which gave quite a varied flexible joint).
I then glued the pipe "insitu" trimming the angle to match the inlet of the J-2 engine. Also added a couple of "holding brackets" also from the addition parts for stage 2.
This enabled me to attached the ferrous paper for the LH2 line feed on the body of the rocket
To finish things off I added a bit of pipe for the LOX feed entering the thrust structure
And that is it, stage 3 finished. So I took a few photos!
I feel the end is in sight now
Regards
Kevin
