铁路交叉标志，HO比例模型

These are a filing guide and an assembly jig to align parts to make HO scale railroad grade crossing "crossbuck" sig. The guide is for filing dados into the .080" x .080" sign post (styrene stock material). The assembly jig is for aligning the sign blades (styrene stock material) in the dado cuts on the post. An additional sign indicating multiple railroad tracks (styrene stock material) can be located further down the post at the locator ba. After assembly, the sign would be painted gloss white and decal lettering would be added.
The prototype for this model is based on Santa Fe Railway system standards for a crossbuck used in California in the 1930s and 1940s.
This STL file is intended to make ABS parts. Use of any other material may give uatisfactory results if there is a difference in shrinkage.
This is my fit attempt at making a 3D printed item.
Thanks, Rob, at for assistance in teaching/providing 3D printing at the make space in Upland, CA.
