A DIY mouse button, or key, for a 3 button wheelie mouse. This video is for observing the cork post, or riser. A visual review is made of the contact cement as seen near, and beneath, the aluminum ring pull, on the top of the cork post, or riser and integrated cork bridge. The contact cement is also used to seal surface areas of the cork, such as the opposite side of the cork bridge that retains the aluminum ring pull.
