Felt like it was time to make my first addition to this community. It is a self-supporting woodworking square that utilizes a push-tab to assist you to draw straight lines. Woodworkers know that it is a pain to both draw a straight line and move your square at the same time. This expanding and retracting tab will help to solve this. PS. I have no idea what this Boost thing is all about so please don't do it. I am not sharing to get free stuff. I legit just want to share with the community.
