Whirigig Wars 2018 Birds

Whirligig of two gulls whose wings operate out of phase with one another. Parts are designed in CorelDraw and laser cut from 1/8" Baltic Birch plywood. Power is transmitted through reduction gears (increasing the torque and reducing the speed) via brass shafting rotating in brass liner bushings.

Thank you! Was just trying to figure out how to fly multiple birds at once!
My parts will be hand drawn and cut tho... No lazers here

[@ToddAndrewCole]

I admire your excellent craftmanship! Your stand is quite unique! I appreciate all your explanations. Thank you! My only criticism is that the birds should have been parrots. (just kidding)

Nice work. How did you determine the balance needed for the cranks?

[@paulwoodrich6381]

The throw of the crank determines the (wing) movement. The easiest way is to put all the hardware (washers, nut, threaded rod, and push rods) on the journal - then balance that against a weight in opposition. In this case a jacketed bullet from a 44 (a 38 wasn't enough).

Have you tried putting g a counterweight for running one gull?
Would that help?

[@paulwoodrich6381]

Yes, good point, it was easier to add a second gull in opposition (already had all the parts).
