Walschaerts Valve Gear Demonstrator (WIP)

thingiverse

I AM PLANNING TO RE-DO THIS SOON --UPDATE-- I am working on making a DXF set for this, so that it can be laser cut by people who have one. It will be quicker, more accurate, and easier than trying to 3D print it. A model of Walschaerts Valve Gear, used in steam locomotives. Included are all the base components individually, including the pins to hold it all together. The pins are just placeholders really, I recommend using actual metal pins or adjusting the design slightly so the pins work better. I purposefully left large gaps in between components so that inaccuracy in a 3D Print can be made up for. Better to have parts that fit loose rather than not fit at all. Also included is the base Fusion 360 Model, so you can make adjustments if you wish, or see the process of how it was made. The expansion link is quite roughly done, it's just functional (I hope) and not pretty or precise. I have marked the design a Work in Progress, as I am currently attempting to 3D Print it myself just to see if it actually works, no guarantee that is does currently. Once I see how it all goes I will update the page accordingly. The scale is such that it can be printed on an Ultimaker 2 Extended+, the printer which I use. I recommend using a wooden base plate, with tighter tolerances that what I have used here. Made in Fusion 360. If you want the design modified in any way, let me know and I'll see what I can do.
