<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 34:</strong> Cut a 1.5x1.5x9.5 inch square column on the [[Table Saw|table saw]]. You don't have to shorten the workpiece to 9.5 inches just yet, but it will make the work on the wood drill press much easier.

<strong>Step 35:</strong> Cut the four holes using the [[Wood Drill Press|wood drill press]].

<strong>Step 37:</strong> Cut the four triangular pieces using the [[Vertical Wood Bandsaw|wood bandsaw]].

<br>
<strong>Step 38:</strong> Flatten a length of 1/2-inch wooden dowel down to 3/8 inch using the [[Belt/Disc Sander|belt/disc sander]]. Cut the flattened dowel into four pieces a bit longer than you will need for the fipple blocks using the wood bandsaw.

<br>
<strong>Step 39:</strong> Test the fipple blocks before gluing. Take note of the placement of each fipple block that gives the best sound for each hole. You can use a bit of extra wooden dowel to hold them in place.

<strong>Step 40:</strong> Glue the fipple blocks in place and use a bit of extra wooden dowel to hold them in place. Let the glue sit overnight before working on the train whistle body again.

<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.

<br>
<strong>Step 42:</strong> After the glue has dried on the train whistle body, use the wood bandsaw and the belt/disc sander to remove the extra length of the fipple blocks.

<br>
<strong>Step 43:</strong> Glue the mouthpiece on top of the train whistle body and let it sit overnight. Once the glue has dried, your train whistle is ready to make some noise. Feel free to sand the edges down, hand-carve or burn-in a design, stain the wood, apply lacquer/finish, and/or engrave something on it using the [[Laser Cutters|laser cutters]]. Enjoy!
