What better way of applying the scotch yoke could there be than a project featuring Nessie, the Loch Ness Monster!
I do most of my planning in my head. It might look like I'm sitting around drinking coffee and gazing vacantly into the middle distance but actually I'm working hard! Today I've been working out how the mechanism for a Nessie model could work. I've settled on the above which I reckon is do-able. The Scotch Yoke at the centre of the model drives the dark blue slide back and forth. The circular pins on the slide push into the bell cranks moving the head and tail up and down.
A rack and pinion on top of the slide rotates the two wheel pieces back and forth making it look like the body is undulating through the water.
Watcha think?

This looks really cool! I can't wait to see what you do with ole' Nessie!

Hey that is indeed an idea!
Nobody has seen the Loch Ness Monster so Nessie's face is just right.
Two middle pinions can reveal two different colors one after the other under the same outer spot pattern - a secret nobody has discovered it yet.
The challenge would be to decide how big the diameter of the wheel needs to be. Good luck, Rob - this is an excellent idea.

This looks really cool Rob! I hope you get it finished soon as I have a foot in plaster at the moment and am very bored!!!

The combination of three mechanisms in a model is fascinating. That will be no easy task.

this project looks great hope you are able to make everything work together so nessie can come to life
and what a great use for the scotch yoke mechanism then using the monster from scot land itself not sure if you even realized that little word connection =p
