Set 4 Tutorial building the machine "Discovery"

Send by email

The best way to learn is to do. Below are the step by step instructions to make a creation with Set4. We have many standardtutorials that can deeply explore mechanical motion & machines. We have found that if students go through the step by step construction process it has a profound effect on creating interest and actions to learn.

 

Step 1- Screw in the Posts.

The post position is identified by column, alphabetically from left to right. The student finds the column and then counts down the required number of holes to identify the correct post hole. The correct "Unit" length post ( 1U, 2U, 3U, 4U, 5U or 6U) is then inserted. "Discovery" required 11 posts in total. Post positions and unit length are given below.

A8-2U, C13-3U, D5-3U, F8-1U, G3-3U, K5-1U, K10-5U, N4-4U, O12-3U, Q5-4U and Q9-4U.

After completion the board should look like the picture.

Note: Posts should be tightened in place by the cogworks  wrench.

 

   

Step 2- First Layer of Pulleys & Gears

Install the Qty 3 6cm pulleys, Qty3 12cm-24 tooth gears, Qty 2 6cm-12 tooth gears. Install brass "1U" spacers on any post without a gear or pulley. Inserts brass close coupled drive pins on the gears and pulleys as shown. Attach Belt17 ( "17" is length in cm), coded green. Install stainless steel shaft collar on any fully populated post.

 

 

 

 

Step 3- Second Layer of Pulleys & Gears

Install the gears, pulleys and spacers as shown. Attach Belt14 ( "14" is length in cm), coded red. Install stainless steel shaft collar on any fully populated post.

 

 

 

 

 

Step 4- Third Layer of Pulleys & Gears

Install the gears, pulleys and spacers as shown. Attach additional Belt14 coded red and Belt17 coded green. Install stainless steel shaft collar on any fully populated post.

 

 

 

 

Step 5- Fourth Layer of Pulleys & Gears

Install the gears, pulleys and spacers as shown. Attach Belt16 color coded orange. Install stainless steel shaft collar on any fully populated post.

 

 

 

 

Step 6- Add the crank !!

 

 

 

 

 Step 7

Add reference markers via brass knurled screws, crank and study the motion !! Watch it in motion.
