Big Wheel Lift #2


The Big Wheel Lift is an interesting automata that people enjoy watching.  This is a Jim’s Gym piece of exercise equipment.  The biped both pedals and pulls levers to power the big wheel.  The big wheel lifts marbles to the top.  The marbles fall out of the big wheel and roll to the bottom of the wheel, passing through three magnetic shock absorbers on their journey.

The Big Wheel Lift is powered by both hand crank and by electric motor.  When under electric power the Big Wheel Lift  will either cycle 12 marbles (and then stop) or will operate continuously.  As I write this (8/22/2019) Big Wheel Lift #1 has cycled 21,000 marbles.

Approximately 25″ wide, 21″ high, and 9″ deep, and weighing about 8-1/2 pounds.

Scissor Lift #2


Scissor Lift #2 is the last ‘hand crank only’ automata that I will build.  This is a Jim’s Gym piece of exercise equipment.  The biped lifts two levers, which in turn feed marbles through a mechanism which lifts them one at a time to the top.  From the top gravity pulls the marbles back down to the bottom.

This machine is operated by hand crank…is very smooth…a pleasure to operate.  

Approximately 25″ wide X 18″ high X 9″ deep.  Weighs about 8 pounds.

How to Purchase:

Generally speaking I do not keep automata in stock…rather I build on a commission basis.

Purchase:  If you wish to purchase an automata that is in stock:

  • The selling price does NOT include packaging and shipping.
  • James Coffee Studios accepts major credit cards.
  • Local pickup would be wonderful.  Perhaps I could deliver.
  • Contact me via either phone or email,

Commission: If you wish to commission me to create an automata for you:

  • I describe the process on the Commission page.
  • You should allow 3 months for the completion of the automata from the date of signing the Letter of Intent.
  • Contact me via either phone or email.

Warranty:  This is a complicated subject.  My thoughts;

  • These automata are little machines that have gone through rigorous testing.
  • These automata are fragile works of art.
  • At this time I offer no warranty.
    • I would like to offer a lifetime warranty…but that is not reasonable.
    • I would like to offer a one year warranty.  If the automata is located close by and if it can be brought to my studio I would do what I could to effect repair. 
      • If the problem appeared to be a design flaw I most likely would not charge for my time.  If the problem was caused by abuse or by commercial use I would charge for my time.  I charge my shop time at $25.00 hour.
    • Shipping can be a problem.  These automata can be fragile and must be carefully packed for shipment.  This is not a trivial process.
  • At this time I do not offer a warranty….however in any situation and regardless of the time that has flowed, I would do my best to help the owner obtain effective repair.

So, bottom line I offer no warranty but I would do all I reasonably could to help the owner obtain effective repair.  It will be interesting to see where I stand in five years (2024) on this important issue.
