Multiple Cam Progress

Sun, 27 Oct 2013

Three cams and three followers mounted into a box and looking, I think you'll agree, ready for business! 


It works nicely, but for certain shapes of cam the main push-rod bumps into the cam itself. 


Here's the original cam follower design, there is very little room for movement with wider cam profiles.


By modifying the design so that the follower is offset one way and the push-rod the other the cam follower has a much greater range of movement.


The business end of the push-rods.

Next step, a suitable way of joining these ends to vertical push-rod and thence to a character.
