rbrown7713 Posted May 5, 2015 Author Share Posted May 5, 2015 I am installing flush windows in the MTH passenger cars. They look more scale because the windows in the cars are almost flush to the outside. I am cutting them on a CNC mill and they fit well without glue. I am experimenting right now, but here are some pics. I might have to paint around the windows, black, to make them stand out more. I might not have them close enough to the outside, still trying the fit. Bob. Quote Link to comment Share on other sites More sharing options...
SteamPower4ever Posted May 5, 2015 Share Posted May 5, 2015 Very nice. That was one of my objections to the models. You know, Bob, you could be making up the recipe for an irresistible bash Jens Quote Link to comment Share on other sites More sharing options...
rbrown7713 Posted May 6, 2015 Author Share Posted May 6, 2015 Thank you. I just tried painting around the glass black and because of refraction, it makes the glass look thinner and more realistic. I am now experimenting with shades. Bob. Quote Link to comment Share on other sites More sharing options...

rbrown7713 Posted May 6, 2015 Author Share Posted May 6, 2015 What happens sometimes, is that I have to wait till next payday to buy supplies, so I will work on something else to keep the momentum going. I receive urethane and stuff today, so I will continue on the viaducts and the passenger car. I am cutting out flush windows for the car today, I think they will add a little to the looks. Bob.

Jerry B44 Posted May 6, 2015 Share Posted May 6, 2015 I understand the payday. Got my 63 Galaxie back from the body shop, so now broke till my VA check comes at the end of the month. Quote Link to comment Share on other sites More sharing options...
rbrown7713 Posted May 8, 2015 Author Share Posted May 8, 2015 OK, here is the final mold for the stretch section. All I have to do is wax and apply mold release and pour the epoxy. Next, will be the part. Bob. Here are some pics. Quote Link to comment Share on other sites More sharing options...
rbrown7713 Posted May 9, 2015 Author Share Posted May 9, 2015 Here is the stretched section. It came out well, even after my epoxy started to jel. It is usable. Bob Next, I will pour a fluted section. Quote Link to comment Share on other sites More sharing options...
rbrown7713 Posted May 9, 2015 Author Share Posted May 9, 2015 OK, it's together, so now some paint and fill in part of the skirt and mold the roof, so not quite done yet, but close, the hard part is done. Any ideas about matching the paint? If not I will paint the whole thing. Bob. Here are some pics. Quote Link to comment Share on other sites More sharing options...
Jerry B44 Posted May 9, 2015 Share Posted May 9, 2015 Looks good. Ingenious mold to cast a hollow piece like that. I found Tru Color paints matched the MTH color for UP yellow real well, might get some and see how it matches those colors. Where did you get the diaphrams? Look pretty good.

rbrown7713 Posted May 9, 2015 Author Share Posted May 9, 2015 Thanks, Jerry and Jens. If I can, I want to stay with the B&O colors, if not, well something else, but thanks for the hint. The diaphrams are the stock MTH. They are nice, but they don't move, but I will fix that. Bob. Quote Link to comment Share on other sites More sharing options...
rbrown7713 Posted May 10, 2015 Author Share Posted May 10, 2015 Well, here is my answer to the diaphragm problem. Rather than going to all of the trouble of constructing the fabric diaphragms that are on the right, I will use the stock ones and make them rotate. I am figuring out the springs now, haven't yet, but here are some pics, I think this will work. Bob. Quote Link to comment Share on other sites More sharing options...
Jerry B44 Posted May 10, 2015 Share Posted May 10, 2015 Bob, i'm sure Tru Color has B&O colors, might test it out. I think my curves are too small to do that thing with the bellows. I have a bunch of cut out foam pieces that must have been with Great Trains. Might rubber cement one on each car and see how that works out, they are gray.

rbrown7713 Posted May 10, 2015 Author Share Posted May 10, 2015 Thanks for the heads up on B&O colors. I will be operating with 10 ft. radius, but after I get into it a little further, I will let you know how tight of a turn they will negotiate. I think pretty tight, because when they turn tightly, I think they will actually move away from the other diaphragm. I don't know yet, but I will see. Bob.

rbrown7713 Posted May 12, 2015 Author Share Posted May 12, 2015 Thanks again Jerry, yes and I did it with a router, no mill. Here are some pics. of the diaphragm, it works. Mounted two springs behind the door. I will be able to close the gap to the cars and it will look more realistic. Also, the first half of the roof mold. Bob. Also, I found the Tru-Colors for the B&O and ordered the paint. Thanks for the suggestion. Quote Link to comment Share on other sites More sharing options...
rbrown7713 Posted May 14, 2015 Author Share Posted May 14, 2015 Hello everyone. I put a short video on YouTube showing the movement of the MTH diaphragms.

rbrown7713 Posted May 19, 2015 Author Share Posted May 19, 2015 Here is a tool to remove the ridges on the roof of the MTH passenger car. I made it from a reducer, copper, and cut it as shown. I attached it to a Dremel and it is designed to cut without gouging. The prongs are the same width as the cutter, so it will only cut when the tool is a 90 degrees. There are some areas that the tool will not fit, so those areas will have to be done by hand without the aid of the tool. I redesigned the movable diaphragms and am making molds for them. Here are some pics. and an example what the roof should look like. The Pullman standard roofs are welded seams and are flush. Just trying to make them look more scale. Bob.
