Jases Battlestar Galactica

[JAWS]

have some time to myself & the choirs are done. Thought I would get these Saturn V parts cut to size for the top & bottom engine decks. Gotta say that it wasn't fun. I tried 2 methods. First with ruler blue tacked to inside of rocket for stabillity whilst cutting a run line. That actually worked the best for me. The second was with the Dremel & a cutting tool. It worked pretty good also but I felt I had mor control with the knife so the knife it is. Ive taken a good even section off each side. About 10mm to start & the rest I'll bring in with the sand paper. I then went about cutting the dome in half for the rear sections. I used some electrical tape lined up through the centre & an exacto blade to run a score line. i then went over again & again & again until it started to seperate. I did have 1 small slip but recovered quickly & wont be seen.
QUESTION: Do the dome pieces have to be flush with the rocket houseing? A couple of pictures I saw a gap? Was it just the angle?
