After seeing the fantastic results from Serge Y. Lebel and Sarah Griessenböck I made the plunge and bought the Elegoo Saturn and built a home made curing box. We shall see but I suspect great things from this.

One part is an O scale journal box for the SDL39 project and the other is a signal box cover in S scale. These will be prototypes for the brass castings.

Great looking prints there Dan! I tell ya, I got an FDM printer but I often look at the resin printers and think I ought to upgrade. FDM is just so darn easy and convenient. Turn it on and go. No clean up needed afterwards.

Your links don't work (or didn't work for me).

Am I to understand these will be used as patterns in casting???

And lastly, are you aware of the print repository on the forum?? You can contribute and download files for you own use.

Can anyone else smell this picture? I use a full respirator and can still smell this stuff sometimes.

Yeah Alan, easy to print if you want the basic shape......BUT, if you want all the details i.e. the lettering on the case door,  and all the inyticacies of the H-5 signal, it might not be so darned easy.    If I wanted the basic shape, I could make that out of styrene, I want a detailed version of the real thing in O scale, not a Lionel looking signal.    If BLMA could do the H-2 signal in HO, why can't someone do that in O scale?     This is 2021, not 1950!  We should ask for, and expect more out of model manufacturers.   Sorry to get maybe off topic on Dan's thread.   OIP

Pretty sure you're not getting the lettering on the case door on any scale model. What's that thing, 1 or 2 feet high at the most? That's 1/4 to 1/2 inch high in O scale for the entire case.

As Magic said that was a quick model based on a couple of photos. If you have more detailed dimensions (in decimal not fractions) of the various parts and the lettering, I can do wonders.

Without more detailed information, the best I can do is that model I showed.

I don't know that the model I made's dimensions are correct!

I just Guessed!

I fully get your gist Alan.   From what I gather, using a 3D camera to photograph things, really helps pop the details for this type of work.   Regarding the  fine details.....the BLMA HO scale, H-2 signals actually have the lettering on the signal housing.  Remarkable detail, needing really good magnifiers to see!   B.T.W., I have a H-5 dwarf signal at home, along with a H-2 dwarf.   Neat signals, BUT heavy!

@railroad-guy (Dan) What are you using to make your molds from these prints?  I'm trying to catch up as fast as possible with all this.  FYI: I'm using the Elegoo Mercury Plus wash and cure machine.  Here's what I've been CADing the last couple of days...

CAD-Capture

Glenn, my friend who actually does that part, uses some high end rubber compound, red I believe. Here is DECO end for C&O and some B&O 1937 boxcars. Rich Yoder did a brass car with this end a while ago but it was never done by anyone else. This would fit an InterMountain car and possibly Atlas.

   Alan, yes I do!  I took drafting in HS, lots of fun, I like drafting class.  We had a real oddball of a teacher, (Major Altum) and yes, his first name was Major, who walked around the classroom with a toothpick in his mouth.  If he saw a mistake, he would get your attention with a very loud and annoying, "what's the malfunction".    One day, a classmate brought in toothpicks for everyone.  It took almost the whole hour for the teacher to catch on.    My older sister, used to call him "The great bird of paradise", yes he kind of resembled an egret!!

   When I get the chance, I will take some photos of the H-5 signal.  I have it out in the garage, and need to clean it up, and repaint it.  Been going to do that since spring, but as usual, been busy with other things.   Story of my life, it seems.

RN-  remember those HS drafting courses (I'm old).

What I like is a Front View, Side View(s) and Top View (scaled and dimensioned) along with a 3/4 view  to make an accurate  3D model.

Usually I have a photo and I try to just scale it.



and if there are bottom details then a bottom view too.

A copyright is a unique adaptation of an idea. A good example is a photo of a train signal; that photo is capable of being copyrighted. 

The photo is not the idea itself.  The idea of a train signal is not copyrightable.

So if you make an "exact" 1/4" scale model of an existing train signal, is that copyright-able??. Since the model is not unique being a copy, it is not copyright-able.  The difference between the photo and the model is what else is around the signal in the photo. If the photo is taken at a unique orientation that is not a copy from another photo it is copyrightable.

So could the signal manufacturer claim your 1/4" model infringes? Yes, but only if their signal is unique and has been copyrighted. (Patents are whole different issue.)   Which is why toy train manufacturers that make models of existing engines with unique markings must pay to use those original copyrighted designs on their scale models.

Further, if I take your 1/4" scale signal model and make my own model of your signal model, I have not infringed because you do not have or could ever have a copyright on your scale model of an existing signal. Your signal model is NOT unique.

Not sure I agree, technically if I create a model of a real train signal for modelers and attempt to sell it, the maker of the real thing could go after me (I doubt they would bother, but technically I think they could) for the image of the design,which they own. On the other hand if I made a train signal free lanced, not based on any prototype, no one could sue me on the grounds that it was a train signal, it has to be specific. A photo of a train signal is staged in a certain way it is a copyrighted image; on the other hand if I take a picture of that train signal that looks the same as a picture someone else took, my picture is my own copyrighted image s since I didn't use his. It gets fuzzy if I digitize his picture, use photoshop to have someone climbing the signal put into the picture, that could be considered a violation , because I didn't have the right to use the original image. If I was doing that for the purpose of satire, though, or protest or parody or something, it would be fair use). Edward Hopper's "Night Hawks", a painting of depression era people sitting at a coffee shop late at night, has had many parodies of it done, where for example they have famous people like Bogart and Marilyn Monroe sitting there and they are legal

If someone wrote code that allowed producing an HO signal and I modified it to print out a 1/4" scale model but used their code, it would be a violation of copyright, unless the person who coded it put it in the public domain. Simply modifying the scale would not be considered a new copyrightable work, would still be in violation. On the other hand, if you significantly change the code, to add details,make it represent something else, it may be considered enough of an improvement to be your copyright, but that is kind of gray area.

If you make a unique train signal that is not taken from a actual signal; like one with a triangular face; then yes you would own a copyright in  that unique interpretation of a signal design.

Of course who would want to pay for that!.

Using someone else's software to design a signal does not give the software owner any rights at all to your signal design. That would be like saying that a camera manufacturer owns a copyright in all pictures taken by one of its cameras.

The medium does not control the message... ask FaceBook.

However, to have a copyright the message must be in a medium.
