rbrown7713 Posted January 26, 2018 Author Share Posted January 26, 2018 Here is the first side ready for the second part of the mold. Received my urethane and will be pouring the rest of the molds. I am broke for this month, as I have spent over 1,000.00 for urethane this month, and shouldn't need any more for now. Just looked at the mold and forgot the bridge spars, so not ready. Bob.

rbrown7713 Posted January 27, 2018 Author Share Posted January 27, 2018 Well, it was bound to happen. I have been batting a 1000 for along time, but my average has come to an end. I was making an effort to pour two parts to the mold, so that I wouldn't have to pour the walls down a very narrow channel and in doing so, I overlooked the fact that the opening to the center of the end was was not filled, so, yes I made a mistake, but not all is lost, in fact this might turn out better than my mistake. Now, I will have a three part mold and make it even easier to get the part out of the mold. What I will do is pour through the door, making the third part of the mold and filling the void and then after that, pour, part two.. Sometimes making a mistake is good. Bob.

rbrown7713 Posted January 28, 2018 Author Share Posted January 28, 2018 OK, after correcting my mistake, I am ready to pour the final part of the mold, and worked out better than my original plan. Bob. Quote Link to comment Share on other sites More sharing options...
rbrown7713 Posted January 29, 2018 Author Share Posted January 29, 2018 The pieces for the mold for the Amfleet ends came out great, so my mistake was very helpful, Bob. Quote Link to comment Share on other sites More sharing options...
rbrown7713 Posted January 30, 2018 Author Share Posted January 30, 2018 I am making an effort to make some grills for the Superliners and here is what I came up with, a little jig to hold the vanes. Bob. Quote Link to comment Share on other sites More sharing options...
rbrown7713 Posted January 30, 2018 Author Share Posted January 30, 2018 This is what it looks like. Bob. Quote Link to comment Share on other sites More sharing options...
enginear joe Posted January 31, 2018 Share Posted January 31, 2018 For me, the hardest part of scratch building is getting the small details right. I like how you handled this. I should know to build a jig to take the error out of handling these small vanes. Quote Link to comment Share on other sites More sharing options...
rbrown7713 Posted January 31, 2018 Author Share Posted January 31, 2018 I am interesed to see how everyone else builds these vents, please share them, as we will all learn something. I was going to build these, two per car, but I am lazy, so I am attempting to turn this one into a pattern and then, of course, make a mold. It takes too long for me to assemble these one by one.

enginear joe Posted January 31, 2018 Share Posted January 31, 2018 The vents I model on modern diesels, are folded screens mainly. They act as air intakes or vents in real life. There are (something like) the vents you're modeling here on the rear sides of the SD70ACE engine I built. Much less parts involved. Mine are slightly skewed if you stare at them straight on. I have never attempting making the window shades on the insides of my passenger cars. I think that alone would make me go crazy! Quote Link to comment Share on other sites More sharing options...
rbrown7713 Posted January 31, 2018 Author Share Posted January 31, 2018 I realized that after making the shades for the one stretched MTH smooth car, I should have used even thinner plastic, so if I ever make them again, I will use thinner plastic for the shades. I made the mold for the Superliner vent, so I will see how it came out tomorrow. Bob. Quote Link to comment Share on other sites More sharing options...
Jerry B44 Posted February 1, 2018 Share Posted February 1, 2018 Could you run thin metal through a crimper tool? On the blinds I had success using tape that has the strings in it and taping on the inside of the window. Couple of thin strips served as the one part of the 'blinds'.

rbrown7713 Posted February 1, 2018 Author Share Posted February 1, 2018 I made a mold for the vent, so that should do. That is a good idea Jerry, those blinds look fantastic, show us more, maybe a closeup of the the tape and where you get it, Bob. Quote Link to comment Share on other sites More sharing options...
Jerry B44 Posted February 2, 2018 Share Posted February 2, 2018 Bob, that is just regular packing tape you can get anywhere. The silver part is thin striping tape you put on first. Then put the tape over that and trim the sliver some if you need to. Table top is a photo I reduced from a picture I took of our UP stuff we have collected. Glasses are plastic tubing. Figures are those cheap ones you get on ebay. Repainted some of them, especially the hair, ALL the figures have black hair! Quote Link to comment Share on other sites More sharing options...
rbrown7713 Posted February 2, 2018 Author Share Posted February 2, 2018 That's amazing, fooled me. I will try some of your genius, thanks Jerry, looks fantastic. Bob. Quote Link to comment Share on other sites More sharing options...

rbrown7713 Posted February 3, 2018 Author Share Posted February 3, 2018 Need help with how to apply the thin welding cement to weld styrene. Some say that they use acetone, is that true?, and if not what is the best to use, trying to get away from glue buildup. Bob. Quote Link to comment Share on other sites More sharing options...
enginear joe Posted February 4, 2018 Share Posted February 4, 2018 I tried several things and they all failed. Take some small scraps and try Gorilla Super glue on them. Let them dry for 24 hours and then try to rip them apart. I won't use anything else anymore. Just not on windows. Quote Link to comment Share on other sites More sharing options...
rbrown7713 Posted February 4, 2018 Author Share Posted February 4, 2018 OK, I will try that. Bob. Quote Link to comment Share on other sites More sharing options...
enginear joe Posted February 4, 2018 Share Posted February 4, 2018 Like all these chemicals, have a fan blow the fumes away if you glue a big surface or you'll feel it. Quote Link to comment Share on other sites More sharing options...

rbrown7713 Posted February 5, 2018 Author Share Posted February 5, 2018 Anyone have better drawings than I have? My drawings came from the 1982 Model Train magazine, but doesn't give the lower sheet metal angle of the side, as it angles in at the bottom. I tried to get the angle from the drawing with a protractor and came up with 7 degrees. Anyone have a better number? I would appreciate it. It seems that all of the measurements were on the drawing except that angle. Bob. Quote Link to comment Share on other sites More sharing options...
enginear joe Posted February 5, 2018 Share Posted February 5, 2018 No better answer from me. It almost seems like they change with the type or when they were made? Hard to tell unless you pick the exact prototype of each car. I think some models are overdone on the end curves. More slope on the long center bottom panels but still not much. look how curved this model ends are Quote Link to comment Share on other sites More sharing options...
rbrown7713 Posted February 5, 2018 Author Share Posted February 5, 2018 It looks like another trip to Sanford for measurements. I don't think that model is correct with the curved lower section. I like the sign on the end of the car "Do not hump", while I really like building these cars, I can't see any situation that would cause me to do that. Bob.

rbrown7713 Posted February 5, 2018 Author Share Posted February 5, 2018 I just got back from Sanford to make the measurement of the fairing and the drawing is correct, 7 degrees. So, that is what I will go with, Bob. Quote Link to comment Share on other sites More sharing options...
rbrown7713 Posted February 7, 2018 Author Share Posted February 7, 2018 Almost ready to glue the sides. I am using two pieces of .040 sheets on each side. Bob. Quote Link to comment Share on other sites More sharing options...
