25. Remote turntable mechanism - PoC

Oooh, I love me a mech.

 

Here's a quick-n-dirty Proof-of-Concept construction showing my initial ideas to drive remotely the turntable (WiP from a few days ago). That in itself is easy enough, but I figured there might be 'emergency' conditions when one would prefer to spin the turntable by hand quickly, in which case the worm drive would prevent that. So the other part of this mech disconnects the worm drive enmeshment with the 40T cog.

 

Operation:

• In Position A, the black handle at the back turns the worm gear and thus the 40T cog turns (upon which would be mounted the turntable).

• In Position B, the red-handled shaft is pulled out thus pulling the blue beam, rotating the grey crank and pulling on the lime-green bush. This will pull the worm gear off the 40T cog (possible on account of the uni joint), enabling the turntable to be spun round relatively quickly using 'The Hand of God' (cue trumpets and angelic choir music).

 

The two uni joints further north enable the axle drive to come up a plate's thickness, since otherwise the worm gear would rub on the studs.
