Technic 1977

[Takeshi Takahashi]

I feel like these last two would be "simple" enough to try out LDCad's new interactive animation feature—for those clever enough to do so. 

(By the way, why does the first crank machine have a transparent 1x2 brick? Is that in the file itself, or just the preview image?)

Yes, it's very nice to be animated!!

Thanks for pointing out the wrong colour.
The purpose was to adjust the angle of the rack and I've forgotten to set it back again.
