Railroad crossbuck sign, HO scale model

thingiverse

These are a filing guide and an assembly jig to align parts precisely to create HO scale railroad grade crossing "crossbuck" signs with accuracy. The guide is designed specifically for filing dados into the .080" x .080" sign post made from high-quality styrene stock material. The assembly jig, on the other hand, ensures that the sign blades, also crafted from styrene stock material, are perfectly aligned in the dado cuts on the post. Furthermore, an additional sign indicating multiple railroad tracks can be positioned further down the post at the locator bars. Once assembled, the sign would be painted a brilliant gloss white and decal lettering would be carefully added for a realistic finish. The prototype for this model is based on the Santa Fe Railway system standards for a crossbuck used in California during the 1930s and 1940s, providing an authentic representation of the era. This STL file is optimized to produce high-quality ABS parts. However, it's essential to note that using any other material may result in unsatisfactory outcomes due to differences in shrinkage rates. As a newcomer to creating 3D printed items, this project has been a valuable learning experience. I would like to extend my gratitude to Rob, at umakers.org, for his invaluable assistance in teaching and providing guidance on 3D printing at the makers space in Upland, CA.
