Make your own keyboard with integrated trackball mouse

Step 3: Create JB Weld tools & mix JB Weld

I didn't want to try to find something to stir up and apply the JB Weld, so I cut up the box that the mouse came in and made some stirring utensils. They work really well! I recommend making a couple of them, in case one loses its structural integrity during the process.

Once your tools are finished, use the plastic mouse shell that came in the packaging as a good place to put your JB Weld / epoxy, and mix up a small batch!
