Made from tape dispenser centers and styrene, plus Plano parts - not from a box!  |

Made from tape dispenser centers and styrene, plus Plano parts - not from a box! That's an awesome idea. If you want to do another one, my kids will happily dispense all the tape from the rolls! How'd you figure out those were the right diameter? |

Calipers and a Walther LPG car helped, the non concentric reduction was actually the worst part, I have another body almost done - too many projects!

I often work in the shadows of those iconic grain elevators in north Fort Worth, where a steady parade of semi trucks pulling grain hoppers file through the head house. For anyone who wants to model these trailers the Lonestar model is outstanding. I must have a dozen of those kits. But the prototypes aren't always that exact model of trailer, so I've done a few kitbashes of that kit. My latest effort involved removing the twin hoppers and replacing them with a single "super hopper" designed to reuse the kit's detail parts.   Here it is compared to the original kit as-built:  |

Fr8kar, what do you use for software to design your 3D models?

Decided to start on this stack of proto hopper kits:  I’m almost finished with one, but waiting on an order of Kadees before I finish them. I have to paint the inside of the yellow cars because they were molded on yellow. I’m not certain if the lessors would still look like that in the 78-82 range. The RI car will likely become a CNW patch-out, gonna have to research what numbers I could make it. |

Fr8kar, what do you use for software to design your 3D models? AutoCAD 2000. I have to run it on WinXP mode on a Windows 7 machine it's so old. I probably need to upgrade to something better, but this software was paid for long ago. |

Really nice trailers, fr8kar. I've looked at those trailer kits and wondered if they're in any way usable for 1975? The Lonestar models website says they're a 1990 prototype, though the design was already in use a few years earlier. Or were farmers and haulers still basically only using trucks without trailers in 1975? |

It’s free and looks like good design software, but I’m not sure how useful it would be for model train work. Thanks, Mark |

It can give direct commands for CAM / machining operations, a well as 3D printers. You can get a copy for free as a hobbyist. |

I use Fusion360 for all of my 3d work, it has a super save as a 3d file function built right in.
There are many YouTube videos on using it, a fellow named Lars Christiansen is just one of many that have excellent videos.

The Lonestar models website says they're a 1990 prototype, though the design was already in use a few years earlier. Or were farmers and haulers still basically only using trucks without trailers in 1975? As far as 1975 is concerned, I really don't know, Colin. I got started building my own cardstock models of trailers like these in the late 80s, so they were certainly around then. There is some info on Wilson's history here, though not many relevant photos for 1975: www.wilsontrailer.com/aboutTimpte makes similar trailers to the Wilson Pacesetter and Commander. Their history page has a few more photos including a couple from the early 70s. One is a flatbed and the other has the super hopper like I modeled: www.timpte.com/history.htmlAnother really great resource is trailer auction websites. I'm a big fan of purplewave.com. They typically have numerous high resolution photos, so as long as you have some basic dimensions to work with you can get pretty close making drawings from photos (who's going to rivet count your model of a 1978 Doonan trailer anyway?). There are a few matches for your era in these search results: www.purplewave.com/search/grain%20hopper |

You're welcome, Colin. That's where I found all the photos I needed to draw up the 32' Fruehauf aluminum dump trailer I did a few months ago. One broadside view and one end view was all it took to dial all the other dimensions in. If 3D printing trailers wasn't so darn expensive I'd do a lot more of them. It's much more economical to do a conversion part like the super hopper.

TONS of how to's and whatnot on there for Fusion 360. |
