[BCRR] – 3D-printed journal boxes

Posted by Gerd on Monday, 6 June 2016

Last Tuesday, I designed the final version of the arch bar truck journal boxes and ordered 8 pieces at Shapeways in the afternoon. I got the shipping-note on Thursday in the evening and on Saturday, they arrived at my door. What a fast service!

I’m very happy with the result. They were much smaller and more detailed as any conventional made pieces I made before. They match very well to the 90mm wheels I use. The material, White, Strong & Flexible, is also very strong and it’s nearly impossible to deform them. I press fitted a journal box to the ball bearing on one wheel set and they fit well too. Finally, these journal boxes will become the starting-point of new-age more detailed arch-bar trucks for my 2”-scale railroad. And with new and more detailed trucks, I might go for more detailed rolling stock as well…

But first of all, I’ve to finish the Shay…
