Step 2Assemble the rig
After you have your pieces laser cut, you'll have to assemble the rig.
Be sure that you are assembling on the correct side of the book. As the match rig is going on the outside of the back cover, you'll want to make sure that the tiny hole for the string to go through is on the right side when you are looking at that side. This is the hole that the string will come out of and across the outside of the book (inside of the jacket). The string is what allows the device to spring when the book is opened... more on that later.
First you will want to remove the spring from your clicky pen and bend the top end of it into the hole at the top of the slider with some pliers. bend the other end of the spring into the top hole on the back of the book.
The next thing that you will want to do is push staples through the track and holes and to the other side. Close the springs well, but they shouldn't be tight. The slider must be able to move up and down easily.
I used only 3 staples even though there are holes for 4 because the spring provides some friction against the slider, and if you use 4 staples, the friction can jam it.
At this point you should be able to pull the slider up and it should come back down quickly due to the spring.
next you will want to mount the catch. This is easy enough to do, just put the nut and washer through it and add the bolt to the other side. Again, tighten a little bit, but keep it lose so that it can move easily. This is a good point to test that everything is going ok, by pulling up the slider, rotating the catch so that the short end is blocking the slider. releasing the long end with the whole on it should send the slider careening towards the bottom of the book.
