Project Information
I saw a simulation of the Whitworth mechanism on Youtube, and decided I could convert it to a hand-cranked wood model for the kids.
The colored parts are all hard maple, the rest is white oak.
I scroll sawed the 3 gears. I generated the gear design using free program GearDXF.Exe, print it on paper, then white Elmer's glue paper pattern to gear blank, drill the axle hole, scroll saw cut the gear, then wash off excess paper with wet rag.
Grandkids should have fun with this one…........and no batteries are ever required !!
You can see a Youtube video of the model in action using this link.
For details on how I designed and build this model, see my woodworking web site using this link.
