MAKE OLYMPICS - 2018

 Give life to your designs!

Make Olympics is a competition aimed at improving the manufacturing skills of Students at engineering colleges. Every alternate week, we will be publishing instructions for building a product. You need to build the variants and send us photos & videos. Top entries for each fortnight will win cash prize or intership offers or gift vouchers.

NAUTILUS GEAR

A nautilus gear is an odd shaped non-circular gear that follows a Fibonacci spiral.
 
Nautilus gears only work in pairs where both gears are the same size, this results in a 1:1 gear ratio but the delivery of this ratio is quite unusual. If you rotate the driver gear at a constant speed, the driven gear will rotate at a constantly varying speed.
 
One of the uses of the nautilus gear is on oil and gas pumps where a long throw of the piston needs to be finished with a final high pressure slow purge at the top of the valve.
 
This MII competition, we chanllenge ...
 
 
You can refer this Instructable also, but for this competition, you need to fabricate the parts in a CNC router.
 
Since it is a 2D part, cutting in CNC can be done in few minutes, whereas 3D printers will take hours to print the gear. 
 
All the best.

WHAT IS A RAMP WALK TOY?

Ramp walkers are cool toys that "walk" down ramps or in some case are pulled along a flat table by a weight on a string hanging over the edge of a table. 
They are toys that move down an inclined plane powered by gravity in different shapes and sizes as ducks, rabbits, kangaroos, elephants etc. The physics & maths behind these ramp walker toys are very interesting and explained in the following videos:

RATCHET MECHANISM

Ever wondered : Why doesn't a bicycle move backwards when one pedals back? 
Ratchet mechanism is commonly used in bicycles, tricycles, Engine starters, Socket wrenches etc.
