An Introduction to Mechanisms

Learn It

The initial build for this project won't take long.
You're going to build the basic frame of your mechanisms project, before designing the cams.

Build It Part 1

Collect the pieces you will need.

First you'll need the base and the two corner supports.

Apply some PVA glue to the finger-joints of the supports.

Then insert them into the base.

Now take the side struts and apply a little more glue to the finger-joints and along the edges.

Fix them using the corner supports, so that they are perpendicular to the base.

Next you'll need the follower guides.

Apply glue to the finger joints, and insert them between the verticle struts.

And that's the first part of the build completed.

Take a picture of your completed frame and upload it to www.bournetolearn.com.

Build It Part 2

Collect the pieces you will need.

First you'll need the pulley crank handle part - with the hole in it.

Use the countersink tool to countersink the hole and then place the machine screw through it and tighten the nut on the opposite side using the spanner.

Next collect the following 2 parts and place them together as seen below.

Now use some PVA glue and glue the one end.

Now slide the other pulley side (no hole) over the cam shaft.

Next slide the pulley into place and put PVA glue on the flat surface.

Next, place the hexagonal part in place and then glue the flat surface.

Finally, place the first pulley handle in place and slide them to the end.

Now tape these parts to the side of your frame, Do not push it through the frame, as this will glue it in place.
