Bird Box. Crank and Bellows.

You can follow progress of the Bird Box project on the website.
In part two I’m driving the bellows from a crank handle via a bell crank linkage. I’ve used three layer bellows rather than the single layer from the previous model, this allows the bellows to open up further.
I think it makes a really interesting stand alone project. If you agree and you would like to see it as a download on the website, let me know in the blog comments.
My next stage will be to connect the pipes tuning to the crank so that the pitch changes as the handle is turned.
