thingiverse

Current Pickup and Spring Generator for Model Trains Gauge G (IIm) and Gauge 1. Naturally you can use the spring generator not only for model trains... Version 2 released (2018/02/05). Enhancements for mounting options. Version 2.1 released (2018/02/15). In CurrentPickup.scad more design options. In StackedBladesSpring.scad much more mounting options. Most advantage: Size reduction of the spring box. Version 3 released (2018/03/05). Central mounting of the spring possible. Much size reduction. Easier installation. See *.stl files 2 and 3 Version 3.1 released (2018/03/06) Changes: Source code decorated with much more comments. Minor change in horizontal wing size (~ 1mm). Version 4 released (2018/03/25) a) A second central mounting option added: The spring is orientated vertical. See the picture of Current_Pickup_Vertical_Front.stl. This has the advantage of an easier adjustment of the tension of spring. b) Until version 4 the blades were always arranged parallel to each other. Now you can define also a spread angle for the blades. You can see an example for a spread angle of 10° in the Spring_Spreaded_V4.stl. c) Adding much more comments in the StackedBladesSpring_V4.scad file. Older versions of the *.scad file were removed from this thing. Version 4 covers them all. Only the names of some variables were changed. Version 4_1 released (2018/04/05) Error correction: SpreadAngle <> 0 handling adjusted for bottom mount horizontal and vertical springs. Version 4_2 released (2018/04/07) --------------------------------- Error correction for InitialSuspensionHub for vertical springs: Enhanced calculation for strange settings. InitialSuspensionHub_Z set to 1mm instead of 1.5mm MetalPlateHeight set to 1. Advantages: a) Allows an easier production of self made plates. b) With a smaller height the springs can be positioned nearer to the axle(s). 2018/07/03 Platform extender added: If you want to mount a spring behind the second axle, it may be that you need an extender so that the shoes of the pickup will not touch the wheels. Pictures for vertical spring added.
