How To: Mass cast complex parts with a parting line

Check out this detailed video that covers how to mass cast an object with no flat sides. This video is only for very experienced mold makers or the particularly ambitious. When mass casting a part without a flat side, you must create a two-part mold. We create a two-part silicone rubber mold with a clean parting line and then cast the part with Repro. This process can be used in automotive, mechanical, fine art and film special effects uses.

How To: Graph a line using points and slope

Given a point through which a line passes and the value of its slope you can graph the line. To do this first plot the given line. Now taking the slope and using the rise over run method plot a second point. Connect these two points and this gives you the graph of the line. Extend this line further on both sides to get the complete line. The point where this line cuts the x-axes is called the x-intercept and the point where this line cuts the y-axes is called the y-intercept. The important po...

How To: Bisect a line segment

In this tutorial, we learn how to bisect a line segment. First, you need to adjust your compass so the distance from the sharp part and the drawing part is the size of the line. Then, put the sharp part on one side and draw your arc with the pencil. Do this on both sides of the line so your image shows two arcs that intersect each other. Since you have these two intersecting lines, you can draw a line between these to show where the middle of the line would be. Use a ruler to draw this straig...

How To: Find the midpoint of a line segment

A good place to start when you want to learn how to find a midpoint of a line is a circle. Take the diameter of a circle, for instance if the coordinates of the starting point are (1,6) and the coordinates for the ending point are (11,6). The midpoint of a line is the exact central point where a line through these two points would meet. Now the value of y is a constant one as the line runs parallel to the x-axis, the value of x changes by 10, the half of which is 5, this is not the midpoint t...

How To: Line a round cake tin

This film from Woman's Weekly shows you how to line a round cake tin. First you take non stick baking parchment.

For the sides, you roll the tin on its edge, allowing some extra for overlap and a little extra height above the tin. Make a fold a couple of centimeters from the top and then make some cuts from ...

How To: Use rise over run to graph a straight line

In this video the tutor shows how to graph a straight line using the rise over run method. The rise over run trick allows you to graph a straight line as long as you have a starting point and a slope value in the form of a fraction. The first step is to graph the starting point. In the second step he states that the numerator of the slope is rise and the denominator of the slope is run. He says that the rise is vertical and the run is horizontal and shows how do rise and run using those value...
