... particular type of switch and crossing angle. It might be possible to print all the timbers complete with chairs regardless of the curvature and glue them to a template. It might even be possible to print a complete "flexible" turnout base with a single web down the middle (although I'm not sure the geometry will hold up properly in that case.) posted: 30 Apr 2020 20:34 from: Rob Manchester Hi Andrew, Hope you are keeping well. Here is the Tillig HO approach to flexible turnout bases. 2001_301532_390000000.jpg I used them many years ago and they assemble well although they were a little fragile. No sure if you could use the wavy web design in a material suited to 3D printing. Rob posted: 30 Apr 2020 21:08 from: Andrew Barrowman Hi Rob, We've managed to avoid the lurgi so far. I'm spending a lot of time in the shed. Thanks for posting that. I think the wavy webs should be possible with 3D printing. I'm using PLA/PHA which is quite tough and flexible. ...
