We will review our mechanism prototypes, discuss next steps, problems, materials, tools, and design. Also, we will explore more amazing mechanical assemblies.
Review of our Mechanism Prototypes
What do we have so far? Where do we want to be in a week? What is holding us up? Do we have questions on materials? Are there tools or techniques that can get us further along?
Simple Mechanisms can get complicated fast when putting them together.
Crank and pulleys and belt
Simple Mechanisms can get complicated fast.
Another reminder of potentially helpful hardware.
Idler Shaft are great for securing pulleys, bearings, wheels, and individual cams.
Tight Tolerance Shoulder Screw are great for securing pulleys, bushings, bearings, and individual cams.
Prime-Line Products D 1503 Steel Ball Bearing Sliding Door Roller, 1-1/2-Inch, 2-Pack and 1-1/2 Inch Steel Rollers can be used with o-rings, belts, and rubber bands. The 1/4″ bore can be used with all of the 1/4″ hardware you have been provided.
Loctite Red 271. If it needs to stay put, a little Loctite will probably help.
Standoffs, using standoffs makes breadboarding mechanisms easier.
Spacers, are a great way to get elements into proper position.
Your two week Building a mechanism project will be due. You will complete a robust, functioning mechanism
