<strong>Step 14:</strong> Select the Top Plane in the Design Tree and start a new sketch by going to the Sketch tab and clicking Sketch. It also helps to be "Normal To" your sketching plane; you can find that icon by clicking on the Top Plane in the Design Tree. On the Sketch tab, click the drop-down arrow next to the rectangle and choose Center Rectangle. Draw a rectangle centered on the origin by clicking on the origin and dragging. Check the "For Construction" box in the left column before clicking the green checkmark. Use the Smart Dimension tool to make the rectangle a square with sides at 10/16 inch.

<strong>Step 21:</strong> Begin a brand new SolidWorks part for the fipple block (meaning don't build this part in the same screen that you built the train whistle body). Ensure your units in the bottom right corner are IPS. Begin a sketch in the Top Plane and draw a circle that is centered on the origin. Use the Smart Dimension tool to set the circle's diameter to 1/2 inch.

<strong>Step 22:</strong> Draw a construction line from the top-most point of the circle through the origin. Use the Smart Dimension tool to set the length of this line to 3/8 inch (0.375 inch). Remember this dimension (3/8 inch) when you are creating a flat spot on the wooden dowel that will become your fipple block. You can measure this with calipers.

<strong>Step 23:</strong> Use the drop-down menu for a line and select a midpoint line. Draw a midpoint line starting from the bottom point of the construction line horizontally to the edge of the circle. It should span across the circle as shown in the screenshot below.

<strong>Step 27:</strong> Begin a brand new SolidWorks part for the mouthpiece. Ensure your units in the bottom right corner are IPS.

<strong>Step 28:</strong> Draw a circle centered on the origin with a diameter of 1 3/8 inches (1.375 inches). Use the Smart Dimension tool to set the diameter. Remember this diameter because this will be the size of the Forstner bit that we use to cut part-way through the mouthpiece.

<strong>Step 30:</strong> Go to the Features tab and click on Extrude Boss/Base. SolidWorks will need help determining which contours you would like to be extruded. Select the two outer enclosed areas, but do not select the area inside of the 1/2-inch circle. When you are finished, click the green checkmark.

<strong>Step 31:</strong> For this next step to work, you must go to the design tree, drop down the arrow next to the Boss-Extrude (created in the previous step), click on the Sketch icon, and click on the eyeball icon to show the sketch. With the sketch visible, select the larger circle and click on Extruded Cut. You may need to change the direction of extruded cut by clicking the Reverse Direction icon in the left column. Set the depth to 3/8 inch (0.375 inch). Click the green checkmark when you are finished. We've managed to do a neat trick here that creates two separate and unique features from a single sketch. The second screenshot below shows the results of the extruded cut as viewed from underneath. Yay! You've completed part 3 of 3. Save your work.

===Assembly===

===Assembly===

This is one of the things that SolidWorks is really good at... assemblies.

<strong>Step 32:</strong> It's time to assemble the three parts we have built into the finished product. SolidWorks assemblies are one of the greatest advantages of this CAD software because they allow the user to see how everything fits together and detect errors before starting the building process. For this, we will open a new SolidWorks window and select Assembly. SolidWorks will ask you to import a part into the assembly; find the file containing your train whistle body, click open, and place it in the drawing space. On the Assembly tab, click on Insert Components to add more parts to the assembly. Import the mouthpiece and four fipple blocks (just do it four times). Place them all in the drawing space.

 

<strong>Step 33:</strong> On the Assembly tab, you'll see the Mate function. We are going to use this a lot to tell SolidWorks which points/lines/surfaces will be coincident/parallel/perpendicular to each other. There are many ways to do this. Basically, click Mate, click on two things that you want to relate to each other, modify the relationship with the Standard Mates section in the left column, and click the green checkmark when you are happy. Rinse and repeat. The next three screenshots show this progression. Remember that you can use the Display Style icon to see a wireframe version of the full assembly to ensure all mates and dimensions align. This is also a good time to go to the Evaluate tab and click on the Measure tool. You can record any final measurements that you need before the sawdust starts flying. If everything looks good, you're ready to start building. <!--The next section of this TV shows the building process. -->

 

 

 

 

 

 

 

 

 

 

<strong>Step 41:</strong> Cut a 1.5x1.5x0.75 inch block for the mouthpiece. Use a 1 3/8 Forstner bit and a 1/2 drill bit for the holes in the mouthpiece.
