I have four Walthers Mainline/Goldline 16.000 Gal Tankcars These Walthers 16.000 Gallon tankcars have a vary basic brake assembly. Only the brake wheel and cylinders are there. No airlines nor any airhoses. So I try to add them myself. The intention is not to be prototypical but just to make them looking like working. The first attempt looked great, but I forgot to take into account the free space needed for the movement of the trucks. So the second type the airline was layed close to the tank. This was done the same way on the second car.
 Enhancing Walhers tankcars - bottom by G.Damen, on Flickr The B-end has a valve and an air tank. First the mounting holes are created using a hot needle to melt the holes. The lines are then added to look good and the routing is limited bij the fact that the car can't be disassembled without damaging parts. So again it is about the looks and not to be prototypical.  Enhancing Walthers tankcars - B end by G.Damen, on Flickr The first tankcar with the added brake lines. This looks a lot less naked.
 20 - End result first car by G.Damen, on Flickr For the third and fourth car the airline wil be centered and can then be more free standing without fauling the movement of the trucks. |

I'll post this now since I was having printer issues on Sunday... A while back I drew up an early PS sine wave end for Shapeways, always wanted to do this one yet. Maybe it's possible after all to make these Walthers cars look less wawful (I'll see myself out)  |

Sine wave ends you say. Hmmm.... Very nice!

Sine wave ends you say. Hmmm.... Very nice! Yes sir! Early ones where the topmost full corrugation was flattened off about halfway, presumably just to provide a spot for the reporting marks. As used on some '65 SOU and GB&W cars (with roofwalks!) as well as some Seaboard LCs. Speaking of LCs, I'd make a taller version of this flanged bowtie end for Monon LCs if the interest is there. I'd build a couple, but between SOU and SCL cars I'll probably already have more than I can justify! |

The bug eye marker lights are from the Cannon and Co nose kits. I had spares so i used them on the SD50. |

Really nice work this go-round. Thanks for sharing.

Thanks! Unless you've got some old computer equipment lying around, you're not going to like this answer. I use AutoCAD 2000 (a.k.a. R15) to draw the parts first as 2D drawings then I use some basic 3D modeling commands to go from 2D to 3D. The last operating system this software would run on was Windows XP using compatiblity mode. It's not particularly good at 3D modeling, but if the desired result is something I can break down to primitive shapes like spheres, cylinders, prisms, etc. then I can usually get the job done. Complex curved surfaces are rarely possible (think Dreadnaught ends on a boxcar), at least with the skills I have. The models are also "dumb" meaning they can't really be edited like models made using parametric modeling software. But I've owned this license for 20 years and I'm pretty adept with the software at this point. I used to work in civil engineering and land surveying before I left all that for Uncle Warren's Playhouse, so at least I got paid to learn how to use it. I'd like to move on to something more powerful and capable, but life keeps getting in the way. I know what you mean. I used AutoCAD 14 for quite a few years until it was no longer compatible with my computers. I had been using Autodesk Fusion 360 up until it sounded like they were going to charge us a steep monthly fee to keep using it. It now sounds like they have pull back from that threat now. But I would still like to find a good design program that keeps the files on my computer instead of a cloud, and not likely to turn into a subscription service. |

But I would still like to find a good design program that keeps the files on my computer instead of a cloud, and not likely to turn into a subscription service. This is exactly why I haven't jumped in on Fusion360. The support for dwg files was enticing, but the changes they announced gave me pause. Now I'm leaning toward Alibre or Rhino, but I just haven't pulled the trigger. I'd have to stop what I'm doing in AutoCAD to get up to speed. Honestly I spend a lot of time in a CAD environment - basically anytime I'm in the hotel and not sleeping or eating - and I still can't seem to catch up on my projects. I shudder to think how far I'd fall behind if I stopped to learn new software. Eventually there will be a good time to make the change, but it's not right now. If you can get AutoCAD R14 up and running on an old machine, I can give you some tips for working in that environment (commands, variables, workflows, etc.). It's really simple, like building with Legos only easier.  |

If you want an easy transition from AutoCAD I'd recommend Draft Sight. All the keyboard commands you already know from AutoCAD work in Draft Sight. Its actually made by the company that makes Solid Works specifically to take the 2D market from Autodesk. Its free for 30 days and then I believe its $99 bucks after that. I use it fairly often at work to edit files before sending them to our laser. When we stopped using AutoCAD it took me less than a day to get accustomed to Draft Sight.

I’m using FreeCAD for my 3d-modeling. It has its quirks, but it is open source. I’m still working on a RP-E4D slug shell with it. I got a printer on friday and can’t wait to give it a try.

Here's a pic. Actually, I think it is by far to detailed for my simple printer.

Here's a pic. Actually, I think it is by far to detailed for my simple printer. Looks like a good start! Nothing wrong with making it too detailed. Later on as printers get better you can print again at a higher resolution. I'm having to redraw some of the stuff I did in 2015-2017 because I tailored the models for Shapeways. Now that I get can better detail I have to go back and make changes which can be a big job. It's just easier to make it right the first time so that's what I'm doing for the new models. |
