  1. I've been using the vector graphics capability in Paint Shop Pro. It's a bit cheaper than Illustrator, but using vector graphics will be a learning curve no matter what software you end up using. But will be worth it when you can resize your decals without loss of detail. Good luck and keep your eye on the prize.
  2. Thanks for all the kind words! I can't wait to get back online in a week or so to view the progress of the other builds. Randy
  3. I've finished my 1/144 Apollo 15 Saturn V model. Here is a photo of her on her stand. She now takes her place in my now complete 1/144 rocket garden of all US manned launchers. Here are a couple of pics. That is 1/144 scale IMR ISS model in the background. Here it is from a different angle. The members of the garden are Apollo 7 Saturn IB, STS-31 Discovery, Apollo 15 Saturn V, Gemini 5 Titian II, Freedom 7 Mercury Redstone, and Friendship 7 Mercury Atlas. Those models were built over the course of about 6 years. It took me a lot longer to build a project when I was working. Now that I'm retired I have a bit more time to build. Now on to the next project.
  4. Well clear coating is done. The stand is complete. The project is done. Here is the final update. I sanded the wooden base block and sprayed it with gray primer. Then after that had cured, I drew three chord lines on it. Then I drew a bisector for each of those chords. Where the bisectors intersect is the center of the circle. You can see that my bisectors were just a bit off, but since I drew three, I could average the difference and come out with a hole that was pretty close to the center. The lines are in pencil so they don't show up well, but you can see the intersecting bisectors. Now I have a center hole to place the rod that will hold the Saturn V in place. I then painted on two coats of flat black paint, then when that had cured I put on a coat of Pledge Clear Floor Finish. Then I put the custom Apollo 15 decal that I had printed on my Alps printer. When the decal had dried I then put on a final coat of Pledge Clear Floor Finish. Here is the base with the rod inserted. Here is a close up of the custom decal I made. The colors look better in person than the picture shows. The blue chevron is actually navy blue even though the picture makes it look black. And here she is, SA-510 Apollo 15, all assembled and on her stand. She's ready to take her place in my 1/144 US Manned Launchers rocket garden. Finally here are a few photos of the details on the finished model. It's been a fun project. Next up is to finish my 1/144 Voskhod, that is about 90% done. After that I think I'll do a 1/144 2001 Discovery or 1/72 Millennium Falcon for a change of pace before I do my next real space subject. I have decided that the next Saturn V I do will have the stages separated and I think it will be displayed horizontally to show all the cool engine details. Thanks for looking, this has been kind of cool to post my progress in this forum for the first time. You guys are the greatest, lots of praise and some helpful hints. I'll be offline for a week or so, since I'm having surgery for a detached retina on Monday. But after that, I'll be back at the bench working on the next project. I'll make a post in the completed build section and show a pic of my rocket garden. Thanks for following along.
  5. Da SWO, We plan on making a video. It will probably be posted on YouTube. I'll be sure to put a link in a post when it goes up. Randy
  6. Pete, The hat shape refers to the cross section view of the stringer. Think of an old style top hat like Lincoln used to wear. Cut it in half and you have the hat shaped cross section that many of the stringers on the real Saturn V had. Making hollow stringers of that type of cross section at 1/48 scale would be crazy, so we used solid strips. In reality the actual Saturn V stringers were hollow. We have a web site (tulsarocketry.org), but we haven't posted the build there. Maybe we should put up a post and point the reader to the build here? Thanks for asking. Randy
  7. In case anyone is interested, here is a list of all the styrene strip that was applied to create this beast. All the stringers were applied to .005 sheet stock and then attached with contact cement. The only exception to that is the S-II/S-IVB interstage. There was no wrap used there. The stringers were applied directly to the rocket. The S-IC aft skirt has 128 3" x 3" hat shaped stringers. These are represented by 4.6" long .060 x .060 strips. The S-IC intertank has 108 corrugations with a trapezoidal cross section. This is represented by .060 x .060 strips 5.125" long. The forward skirt has 216 2" x 2" hat shaped stringers. We modeled those with .040 x .040 strips 2.5" long. The S-II interstage had 216 2" x 2" hat shaped stringers. We again used .040 x .040 strips 1.8" long. The S-II aft skirt has 216 2" x 2" hat shaped stringers. We used .040 x .040 strips this time 1.8" long. The S-II forward skirt has 288 stringers. 144 of them are 1.3" x 1.625" hat shaped stringers. Interspersed with those are 144 1" x 1" I beam shaped stringers. We modeled these stringers with .030 x .040 strips 2.75" long and .020 x .020 strips 1.8" long. The S-IVB interstage had 144 stringers that were 1.2" x 2.162" hat shaped stringers. The closest we could come was to use .030 x .040 strips, each of which was about 5" long. The S-IVB aft skirt has 144 1" x 1.375" hat shaped stringers. We used .020 x .030 strips 1.75" long. Finally, the S-IVB forward skirt has 108 .813" x 1.25" hat shaped stringers. We used .015 x .020 strips 2.5" long to represent those. Note that all the stringers that have a rectangular cross section had to be attached on the narrow side. This was aided by some jigs that Brien 3D printed. They maintained the correct spacing between stringers and greatly sped up the process of making the wraps. He also produced some cutting jigs that helped cut the stringers to a consistent length. If we had not had the jigs and had to apply the stringers the way I had to apply the S-IVB interstage stringers would have put us in jeopardy of not making our deadline. Our local Hobby Town owner helped us considerably with the styrene. We were able to special order the strips and sheets and got them very quickly. He even gave us a discount. He's a great guy. When the rocket gets back from getting it's white paint we will start masking for the detail paint. Then we will apply a set of 1/48 decals from Space Model Systems to make it really look like a Saturn V. Thanks for looking.
  8. Another update. Once the stringers were all in place I then went back and added some umbilical panels to the S-II forward skirt. Here is an overall view of the S-II/S-IVB section complete. Here are a couple of shots of the S-IVB details that got added. They are all 3D printed by club member Brien, except the umbilical connections. I scratch built the umbilical connections as well as the small ribbed strip that runs between the Auxiliary Systems Tunnel and one of the telemetry antennas. Note the LOX Propulsive Vent near the Center on the aft skirt in the photo below. There are a couple of LH2 Propulsive Vents on the forward skirt that have not been applied. We figured that they would not survive a flight, so we are waiting until after the first (maybe only) flight to install them. At this point we are going to assemble all the pieces and get it painted all white by another member. We will then mask and add the black and silver to it. More to come...
  9. Update time. I have finished with my part of the rocket, from the S-II forward skirt to the SM. It took me about three days to finish putting on the stringers for the S-II to S-IVB interstage. There are 144 stringers that need to line up with the larger stringers on the S-II forward skirt and the stringers on the S-IVB aft skirt. First I used a pencil and ruler to mark the transition where each stringer would go. That way I could be sure that everything was lining up correctly and not going askew. There were a couple of fudge spots, but after all the stringers went on it is hard to tell where they are. I also marked where the retro rockets went as well as the personnel access panel. The access panel was scratch built using .010 sheet styrene and some strip stock cut to length and the ends sanded round. I used a combination of Plasti-Zap CA and thin CA to attach the stringers. Each stringer was cut to length one at a time since there were small variations in the positioning of the two skirts. After cutting it to length, I would then place a small line of Plasti-Zap on each end of the guide line, place the strip and make sure it was applied straight. Then wait a few seconds for the Plasti-Zap to set. Then I ran a line of thin CA along the rest of the stringer and carefully made sure the strip was still straight. To keep my sanity I tackled the stringers one quadrant at a time. and placed a 3D printed retro rocket in the center of the quadrant. Each quadrant took about 5 hours to complete, not necessarily continuous. More updates to follow. Thanks for looking.
  10. Pete, thanks. It has been lots of work under the magnifier. Ret, thanks very much. Home stretch time now.
  11. Thanks, Hotdog and crackerjazz. Kind words. The white is Tamiya Pure White in the rattle can. Hopefully I can put this one to bed soon. I'll be delayed a bit while I focus on finishing the details on my part of our club's 1/48 Saturn V. I'll have a post on that in my other thread, 1/48 Saturn V Apollo 11 - Flying model Thanks for looking.
  12. I got the silver painted on the bottom of the S-IC. It turned out pretty well. I've now started applying the decals to the S-IC. Once again, some very tiny detailed decals. Here is a close up of applying one of the forward skirt vent decals over the vent warning decal. You can get a feel for how small some of these decals are here. I'm zoomed in pretty tight, even the toothpick looks rough at this level of zoom. I've completed the S-IC decals. Here is a look at some of the details. An overall view facing POS I. The forward skirt and the LOX tank flag. The umbilical and personnel access door on the intertank. I need more practice scribing. I have a tendency to go too deep. Here is the aft skirt and shows one of the first motion targets on the engine fairings. Here is a view of the aft end looking at POS I. Here are all the sub-assemblies. I'll be putting on a clear coat to protect the decals, then dull coat to take the shine off. Once that is finished I'll attach the F-1's and final assembly will be complete. All that will remain is to put it on the stand I've made. Thanks for looking.
  13. Hotdog, I hadn't heard about that one. I'll let the gang know about it.
  14. Habu, We are planning on a K700. The weight is about 29 pounds. We should get about 2150 ft. Thanks for asking.
  15. Thanks guys. The club is pretty excited about this one. After we fly it on July 20, we plan on taking it to the local Maker's Fair to display. It will have the display aft section on it at that time. Brien Wood is the other club member that has taken on the S-IC and S-II lower sections of stringers. He is also doing the 3D printing of the detail parts. Paul Reed is doing the 3D printing of the F-1 engines, S-IC engine fairings, BPC/LES, and the transitions from the S-II to the S-IVB and from the S-IVB to the SM. Several other members have been doing most of the internal rocket work. The rocket has two sets of altimeters that control the recovery they are on 3D printed sleds by Paul. Hal Ellis has very generously allowed us to use his garage to build and store the rocket as well. By the way, we did do a test flight in December to be sure our calculations were correct and before any details went on. It flew quite well. I'll post the motor and weight details shortly, I don't remember the details just now. Thanks for viewing. More to come...
