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
â¢ Elements of Drill Points â¢ Lip Relief Angle â Varies with the diameter of the drill and hardness of the material â On larger diameters and drills for harder materials, lip relief is decreased to as low as 8Â° â Drills for soft materials and small diameters have high relief angles up to 24Â° â Lip relief angles are measured across the margin
