Hand-Cranked wood model of man cranking a Model T

I decided to modify the man cranking a Model T whirligig, and make it a hand-cranked model as well.

2004 Death of Anders S. Lunde

The original design of this whirligig came from a book written by Anders S. Lunde.  I checked the Internet, and he died back in 2004. I admire his artistic ability to come up with the many different whirligig designs that he did.

Speed Ratio

Since the 3:1 speed reduction ratio for the gearing on the Woman is Boss hand-cranked model worked ok, I decided to stay with it on this model. I did scale the whirligig model down to 3/4 size, just to reduce the over-all size of the model.


I usually do a dry fit, and make sure everything functions ok, before doing final assembly.

In this case, I found some burrs on the wheel spokes I had to file off.....

I had do some trial & error getting the gear to man linkage right.  I measured and the total vertical stroke was 5/8", which meant a stroke of only 5/16".  I ended up moving the brass screw in the big gear from 5/16" to about 3/8".  I also had to lengthen the 2 arm pieces slightly to get it working right.

All brass rods were 1/8" diameter from McMaster-Carr in Chicago. I made thin brass washers, and soldered them to the rods at final assembly. The paint colors were water based Anita's paint bottles from Hobby Lobby.

I put my model design into the Sketchup warehouse. You can download it here.

Closing Thoughts on This Project

I scaled the whirligig portion of this design down to 3/4" scale.  This made a couple of things fragile, which are shown on the illustration above.  I like the 3/4" scale part because it saves storage space.

This was another fun project, and hopefully the kids will have fun with it!
