I’m planning on adding a set of wave on the sides of the the rowing project I’m currently working on.
I have a single drive point at the end of the waves, the slot in the middle allows them to rock up and down. I’ve stacked two layers of waves out of phase with each other, the result is quite pleasing.
The drive pin is in the foreground of the this picture with the alignment pin in the distance.
Check it out in animated action.
