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
1 Drill bits-twist drills used for wood or steel are usually sharpened on a grinding wheel or within a purpose made grinding jig to an angle of 60Â° from vertical (120Â° total) although sharper angles may be used for hard or brittle materials such as glass.ery sharp knives sharpen at about 10 degrees (which implies that the knife's edge is a 20-degree angle). Generally speaking, razors, paring knives, and fillet knives should be the sharpest knives at an angle of 12Â° â 18Â°.
