Current Pickup and Spring Generator for Gauge G (IIm) and Gauge 1

thingiverse

Current Pickup and Spring Generator for Model Trains Gauge G (IIm) and Gauge 1. You can use the spring generator for model trains, and it's not just limited to that. It has a lot of potential uses. Version 2 released on February 5, 2018. This version includes enhancements for mounting options. Version 2.1 was released on February 15, 2018. CurrentPickup.scad now has more design options, and StackedBladesSpring.scad has even more mounting options. The size of the spring box is reduced, making it a big advantage. Version 3 was released on March 5, 2018. This version allows for central mounting of the spring, which reduces its size and makes installation easier. See the *.stl files 2 and 3 to get a better understanding. Version 3.1 was released on March 6, 2018. The source code is now decorated with more comments, and there's a minor change in the horizontal wing size of about 1mm. Version 4 was released on March 25, 2018. This version includes several improvements: a) A second central mounting option has been added: the spring can be oriented vertically. See the picture of Current_Pickup_Vertical_Front.stl for a better understanding. This makes it easier to adjust the tension of the spring. b) Until now, the blades were always arranged parallel to each other. Now you can define a spread angle for the blades as well. An example with a 10° spread angle is shown in Spring_Spreaded_V4.stl. c) The StackedBladesSpring_V4.scad file has been decorated with much more comments. Older versions of the *.scad files have been removed, and version 4 covers all of them. Only some variable names were changed. Version 4_1 was released on April 5, 2018. Error correction: SpreadAngle < > 0 handling adjusted for bottom mount horizontal and vertical springs. Version 4_2 was released on April 7, 2018. Error correction for InitialSuspensionHub for vertical springs: Enhanced calculation for strange settings. InitialSuspensionHub_Z set to 1mm instead of 1.5mm, and MetalPlateHeight set to 1. This has several advantages: a) It allows for easier production of self-made plates. b) With a smaller height, the springs can be positioned closer to the axle(s). On July 3, 2018, a platform extender was added: If you want to mount a spring behind the second axle, it may be necessary to add an extender so that the shoes of the pickup won't touch the wheels. Pictures for vertical springs have been added as well.
