Knex Clock

Brilliant design for the hand. Over comes the lack of correct gearing.

Sizing

The whole thing will be 7' tall.

I'm not sure I want to use corner connectors - I don't think I have enough. Instead, alternate yellows with corner bracing to hold the shape.

Hands

Rather than gears, we'll use rods for transmission. The minute hand will have essentially 2 teeth (two rods at 180°). That goes to a 3:1 reduction, which goes to an 8:1 reduction; for a total of 24. The 3:1 will be a little janky, but feasible.

Winding and Weights

I'd like to do all this with Knex chains rather than string - more authentic; but I'm afraid of how much friction that incurs.

For string, I think I'll use the mason line I have. Fishing line would hold it's shape, causing weird fluctuations in power.

The weights will drop down the center, I need to add a guide track.

Pendulum

As tall as the clock. The pendulum will actually rock in a cradle rather than spinning on a rod - lower friction.
