Yesterday I finally had time to try and finish this up . The 2nd part of Step #16 is attaching the bottom of the Shuttle to the External Tank then attaching the Shuttle itself . Had lots of problems with that last part , the upper and lower wings just didn't want to go together . I did pre-fit them before I started but when the time came it just didn't help , maybe I missed something somewhere . Ignore the right side of this photo , I know I'm holding the wings the wrong way .
The first part was easy taking only a few minutes but the rest took nearly an hour of fiddling with them .
That was it for yesterday so today I continued Steps #17 and #18 , these are what's called the "Tail Service Masts" . They were easy and only took a half hour to complete .
Step #19 is assembling the Mobile Launch Platform .
This was a fairly simple assembly and was finished in another hour .
The final step is attaching the Shuttle Launch Vehicle to the platform , this was made more difficult since the booster nozzles go down into those recesses in the platform . There's no way to see the tabs or the slots they go into so again it was a lot of fiddling around before they went together . At least another half hour spent but it's finally finished !
The Shuttle looks so good that it's a little disappointing they didn't spend more time on the platform , it looks kind of plain to me . Start to finish the assembly time was approximately 14 hours spread over 10 days . I'm going to take some more photos and post them later ,Thanks for following along !
