Linkage Design

Catherine Marshall was a suffragist. The suffragists believed in campaigning for women’s votes through peaceful, polite means. By contrast the suffragettes believed in deeds not words. In this model Catherine and a suffragette stand on either side of a donkey trying to get its attention with a carrot and a stick respectively.

The women’s hands are moved via a cam and cam follower which in turn drives a linkage. I’ve used a heavy gauge wire to make the link. This part is made from a single wire bent into position over a template then fixed into position with a fine brass wire and some epoxy resin.link-01

A small screw fixed to a block on the box top provides a pivot point for the linkage.link-02

Then under the box the linkage is connected to a cam follower. All that remains is to see which is more persuasive; carrot or stick?link-03
