frame tube. Then came the RCS (Reaction Control System) nozzles. I carved them out of balsa wood and made a mold so I could reproduce four of them out of plastic. The other exterior details were made out of basswood. These items were painted and then glued to the SM skin. The white lines are simply white label stock cut to size. The result can be seen in Figure 16. I've had a lot of complements on the details of my Saturn V, but if you think it out, these things can be done without too much work and you'll be very happy with the results. There are always alterna- tive ways of doing things. Just think it through. Now for the really fun part: the Command Module. The real CM is covered during launch with the Boost Protective Cover. 14 MAY/JUNE 2017 SPORT ROCKETRY Figure 12. The upper section of the model (the Saturn V's SIV-B stage) was also constructed using layered cardstock tubes and internal foam board support bulkheads, then detailed with Plastruct. Figure 11. Fin and fairing detail. The basswood fins were fiberglassed. Stringers on the fairings were made from Plastruct square sticks. the Saturn V fin/fairings are unique and John Pursley has detailed drawings that made all the difference to my construction project. Many thanks to John Pursley for his invaluable help with the fairings. You can see photos of the actual Saturn V fairing details on John's site at http://www.accur8.com/S-IC_Fairing.html. Then I fiberglassed the outside surfaces of the fins. The next step was to add the stringers. Again I went to Plastruct 1/8" plastic square sticks and glued them on one at a time. As you can tell by now, I wanted a lot of detail on my bird. After all, the Saturn V deserves it. The upper sections of the Saturn V also have foam board bulk- heads to give extra strength. The transition sections have Plastruct plastic sticks for the stingers glued on individually. It took time and patience, but was well worth the effect and look. See Figures 12, 13, and 14. The skin of the SM (Service Module) is a silver card stock that I ac- quired from the paper company. After looking closely at photos of the Apollo CSM, I recreated the colors, lines, and other markings of the service module in my graphics program (see Figure 15) and printed the image directly onto the silver card stock with a color laser printer. I glued the printed silver cardstock skin to the outside of the SM air- Figure 13. Detailing on the upper shroud (which houses the Lunar Module on the real Saturn V).
