I think this will be a loooong time project, but like to share the entire proccess. Always admired these locos, and in Argentina we had some GE 756, similar to the ones in WP&Y but a little bigger, because they were meter gauge. Anyway, I wanted to model a couple in 0n3, first one from here and then, a couple of WP&Y. I started searching for pics and a friend of mine sent me a couple of drawings. So, I put them in cad and started to design the parts for laser cut. I used styrene in two different thickness, 0.5mm and 1mm. The real challenge will be the trucks, no commercial parts for 0n3. So, jumped to CAD again and drew the parts. I´m working right now in a test model for see if the parts fits OK, and with this test, I did many changes to the original drawing and added more parts and details. Would be nice if I can power the roof fan, should be easy to do. Well, that´s all for now, here are some pics of the test model. Enjoy them!! Showed here is with an H0 model I weathered for a friend, in the back is my 0n3 model.   Here is the laser cut side truck, it has about 20 parts each.  Now, I hope to finish this project , because I have many unfinished, still need some commercial parts. |

Lucas, that's simply remarkable. I'd heard, though, that laser cutting won't work with styrene, because it will melt. I guess not, huh? But I'm simply in awe. |

Thanks John!! It doesn´t melt if you work with thinner layers, for example, the main part of the truck was done in 3 layers of 0.5mm styrene, I tested in 1mm but melts and loose some details. |

By the way, do you or anyone else have photos of the Argentine shovel-noses? I took some photos of the WP&Y units when I was there in 1981, which I'll be happy to share, especially if someone will post on the Argentine ones. |

hey Lucas that is looking great. Your right on the styrene thin will cut but thick melts. I'm play wit some now to see if I can get some setting that will work. rich |

This is going to be VERY interesting. Lucas- that sideframe for the truck is really something! If I were doing it I would have done it in brass--would have taken 10 times longer--and not looked as good. With your craftsmanship, combined with the laser-----WOW! Keep going!! Herb  |

Lucas: It looks beautiful!!! (It even made me feel a bit nostalgic) Did the parts come out so sharp or did you sand the edges? My experience at laser cutting 1mm thick styrene gave prety deformed edges even if it was black styrene which is said to give the less problems. The deforming was noticed more at the backside but at the front the engraved lines became a lot wither than when cutting MDF or wood. Daniel |

Just for fun, here's a shot of a truck sideframe on WP&Y 90: My understanding is that GE cut the components for trucks like this out of steel plate with a cutting torch, so you don't actually see rounded edges. |

Just found your posting from last year. I have been working on building a set of GE Shovelnose units in On3 as well. Would you be willing to share your CAD files? -Eric Portland, OR. USA |
