2 May 2019: The Pedal Pedestal
Big Wheel Lift #1


This past week has been interesting.  I’ve completed the On-Off switch assembly.  This micro switch based assembly is linked to a trip lever on the Big Wheel.  The Big Wheel Lift is turned off after one revolution of the Big Wheel (12 marbles).

And I’ve got the Pedal Pedestal almost completed…should be done tomorrow.  The frame is 1/16″ Baltic Birch plywood.  The sprocket is 1/8″ Baltic Birch, handcrafted and run-in in the test stand.

This morning at 0800 I went online and ordered some drive belt poly tubing from McMaster.  I had the tubing in-hand at 1500.  Can’t beat that service.  I love dealing with McMaster.

The Big Wheel Lift #1 Project Sheet is here.

I’ve done nothing more with A Sunday Drive…but it’s still cooking in my mind and in front of me on the bench.

Regarding motors in my automata:  I’ve just come to the realization of why power cords with the “bricks” at the plug end are powering everything.  I realize now that I should be putting 12 volt motors into my automata, and then powering the automata with the correct power cord…120 volt or 240 volt.  I’ll not change the motor on Big Wheel Lift #1 (it’s 120 vac and will stay in this country).  Future automata will all be equipped with 12 volt motors.  I cannot believe it took me this many years to understand this little piece of international commerce.

The Pedal Pedestal is nearing completion
