Not yet … bit swamped with work, so it’ll have to wait until next weekend.
That would be great.
I will try to post some screen shots of the 3D Leslie RS5 & S5 that I drew using your Information
RS5 & S5 series horns in 3D drawings for 1/87th scale for 3D printing.
The manifold is a bit thick but is necessary for casting properly.

Sweet! Are you going to do any with reversed bells like are found on some railroads?
Yes we will be making several different variations of these as needed for our Locomotive projects and the more popular versions that modelers will want.
These are modular so once I’ve drawn all the individual components I just assemble them in the computer in what ever configuration is needed. The manifold is one piece, each of the bells are separate parts as are the diaphragms. Then I just pick and choose the parts I want to use and tell the computer where to put them and in what direction. The printer then prints the assembly as shown. Keep in mind also that this item is only 7mm across and 3mm high. the longest bell is only 5.9mm long. If you would like a printed scale version of your horns let me know and I will be happy to make one for you gratis.
Very neat, although I’m surprised you can get so much fine detail on the power chambers yet have to keep the manifold so fat.
There are several factors used in deciding what parts to keep scale and which to fudge when working with such small dimensions in brass. One has to do with how the cavity fills. I need a center volume with capacity to flow enough to the outer details that won’t impede flow before the metal begins to cool. I also need enough material for a foundation strong enough to support all the pieces hanging from it. once this is printed in scale I will post another picture of the 3D printed master. The over size nature of that manifold will seem to have diminished at that point. Some of those fine details may not survive the printing and casting process either but I am going to try to keep them if the molding process will hold them. Such is the process of model railroading in 1/87 HO scale.
The end result appears very cose to Solidworks. Nicely done!
We use Autodesk Inventor 3D which is very similar to the solids works which have used in the past. This has a bit more freedom of design and is much more user friendly for the novice user. I have not been to any schooling to use this type of programming so what I do in the drawing is self taught. In the old days we would make each part by hand and fabricate each master pattern by hand. Now I can just draw it once, print and have master in just an hour versus days of filing and fitting. Plus once the main components are drawn assembling and or rearranging them for different configurations take just minutes versus making an additional pattern from scratch for each version. Technology is awesome!
OK… here you go for the RS3. The RS3L has 25, 31, 44 number bells, which were included in the previous RS5 dimension package.
Very simple manifold other than that, so I hope these dimensions are enough but let me know if you need anything else.
That’s Awesome! Thanks very much. I will post pictures of the the 3D version once I have them done
