3D Small Engine Carburetor by Axel Keck

This carb was reverse engineered in 2004 as part of the engine project posted below. Good work Axel!

3D Engine Assembly, 2004

For this project, students were each given different parts to reverse engineer. They took precise measurements with micrometers, vernier calipers, thread pitch gages, depth gages, fillet/radius gages, and a variety of other measuring tools, then created 3D models with AutoCAD. It was a complicated and technical challenge, and the kids handled it very well. Many more parts were modeled, including all of the fasteners, but bringing all of them into this file exceeds the limits of our computers.

The reverse engineering of actual parts is a challenging hands-on/minds-on experience and students get a lot of development out of it. Good work CAD class of 2004! Shown below are 3D exploded assembly views.

Belt Tightener by Matt Kertai

This was created for assignment in 2011. Similar to an idler pulley, it's a belt tightener for vintage, flat-belt driven machinery. The first drawing is a 3D assembly model; the second is a 3D exploded assembly. Good work Matt!

Butterfly Valve by Justin Corl

This 3D valve assembly was created for an assignment in 2010. All internal details, even threads, are included. Good work, Justin!

Pillow Block by Chelci Main

Chelci created this pillow block assembly for a class assignment in 2009. It's a 3D model of the object shown in the post above. Good work, Chelci!
