Bealer’s Bellows Hinge Drawings

Today I thought it might be helpful to post my interpretation of a couple of Alex Bealer’s drawings depicting some of the leather hinging.

The most interesting detail, to me, was how a blocking board was used instead of a leather restraint tether to limit the flapper valve opening.

I thought the Iron Angel blog was a good reference explaining bellows operation and how to make a light weight bellows for using in demonstrations.
