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
Spade bits are for wood, plywood, and some plastics, and cut quickly with surprising precision. Use them only at high speeds, to prevent the bit from catching in the workpiece and the drill from trying to wrench itself from your grasp. Spade bits are found in the range between quarter inch in diameter to one and a half inches. Brad Point Drills.
