You want to know all about photo encaustic. You love photography and want to put more of yourself into your work. You want to have fun exploring your images while being more hands-on. I love that too. That is what drew me to photo encaustic. That and the way the light pulls me into the image.
I would like to know why 118 degrees made the standard tip angle for a drill bit.Or for that matter, 135 degrees? 1. Is there anything called standard tip angle? 2. What factors determine the choice of the tip angle? P.S: I posted the same question in Aerospace forum : http://www.eng-tips.com/viewthread.cfm?qid=347077
RE: Why standard tip angle is 118 degrees? Since drill point angle may vary, do not dimension the angle, but dimension the depth of the full diamater of the hole. The only time you need to worry (and pull your hair out) is if you have a limited space and do not want the drill tip to penetrate the bottom surface.
