Hello
One thing that I have is tenacity. I find it very hard to give up on something, especially when that thing is a challenge. Sometimes it works against me so much that I end up getting very frustrated with it and I will admit, loosing my temper.
My poor Peckett has been a victim of this, some of you know that the chassis has been rebuilt as a result of it bouncing off a door after a flight across my living room. Fortunately the chassis was salvageable afterwards and was rebuilt to working order. I use the word working order lightly as me being me I wasn't happy with the way it was working, some might be happy with the results but not me. The rear wheels were not concentric and the result was the engine had a slight wobble to it when it traveled along the track. This meant that I have now spent a full weekend on the chassis to try and correct it, the end result is what you see below...
I have found that the problem lies with the 3D printed wheels. I dont know though, if its a result of the printing or the way I am assembling them but right now I have managed to get 2 wheels out of 6 I am happy with. As you can see from the photo there are a few which just did not survive the numerous assemblies and disassemblies which happened over the weekend but I am now looking to get some more wheels printed to try and get 4 that I am happy with.
This does raise a few questions though...
1. Is the fault with the way I am assembling them? If so then how can I change or things to solve that problem or tweak the design to aid assembly.
2. Are the wheel rims workable with the printed rims?
3. Is 3D printing in FUD upto the quality to print the wheel centers yet?
4. Would it be better to print the wheels without a central hole and add one after fitting the rims?
I do know though that it is possible to produce a working wheel using 3D printed centers, though its just not as reliable as I would have liked though right now. Having to scrap 4 to get 2 good wheels to me isnt really good enough. One thing for sure though is I am not giving up on this little engine but until I get some more FUD wheels from Shapeways through the post, its going to one side, something I would not normally do...
