This class will teach the\u00a0 basics of anticlastic raising, construction of a spiculum and how to bend it, the concept of trading one curve for another, how to hammer in a twist, and a graphic demonstration of how and where the metal is stretched, and many other concepts.\u00a0 Jerry was selected as one of 12 new designers of the year in 1993 and sells his anticlastic jewelry through galleries and shows nationwide. His work has been featured regularly in many national magazines. Students should have a basic knowledge of metalworking techniques. Vises, some hammers, and sinusoidal stakes will be supplied. If you have favorites including sinusoidal stakes either in steel or plastic of your own, please feel free to bring them. Please bring Hand tools (pliers, files, and any other personal favorites) Each student will take home a finished pair of sterling earrings.<\/h3>\n<h4>Instructor Jerry Scavezze<\/h4>\n<h4>Class is 3 days and the fee is $400.00<br \/>\nMaterials fee will apply.<\/h4>\n<div id=\"attachment_78\" class=\"wp-caption alignright\" style=\"width: 300px\">\n\t<a href=\"http:\/\/userblogs.ganoksin.com\/coloradometalarts\/files\/2009\/01\/style28-copy.jpg\"><img loading=\"lazy\" class=\"size-medium wp-image-78\" src=\"http:\/\/userblogs.ganoksin.com\/coloradometalarts\/files\/2009\/01\/style28-copy.jpg?w=300\" alt=\"14K Gold Anticlastic Hoops by Jerry Scavezze\" width=\"300\" height=\"259\" \/><\/a>\n\t<p class=\"wp-caption-text\">14K Gold Anticlastic Hoops by Jerry Scavezze<\/p>\n<\/div>\n<h4>Tools will be available for purchase.<\/h4>\n<p><!--more--><\/p>\n<p>\u00a0<br \/>\n\u00a0\u00a0<\/p>\n<h2 style=\"text-align: center\"><strong>A<\/strong><strong>nticlastic<\/strong><span><strong> Raising<\/strong><\/span><\/h2>\n<h3 style=\"text-align: center\">By jerry Scavezze<\/h3>\n<h3 style=\"text-align: center\">copyright 1999<\/h3>\n<p style=\"text-align: left\"><strong><span><br \/>\n<\/span><\/strong><\/p>\n<h2><span>Synclastic<\/span> Form (Bowl Shape)<\/h2>\n<h2><a href=\"http:\/\/userblogs.ganoksin.com\/coloradometalarts\/files\/2009\/02\/synclastbowl1.jpg\"><img loading=\"lazy\" width=\"286\" height=\"64\" class=\"aligncenter size-full wp-image-142\" src=\"http:\/\/userblogs.ganoksin.com\/coloradometalarts\/files\/2009\/02\/synclastbowl1.jpg\" alt=\"\" \/><\/a><\/h2>\n<h2>Synclastic forming<\/h2>\n<h3>A technique used to form sheet metal into vessels, etc. The metal is stretched in the center\u00a0and compressed on the edges.

A plastic mallet and a steel stake is quickest but leaves a lot of planishing to be done and offers less control. A steel hammer and a plastic <span>(delrin)<\/span> stake is generally the preferred method. This combination offers reasonable speed, good control and a fairly well planished final form.<\/h3>\n<h3>One of the most important concepts to remember in <span>anticlastic<\/span> raising is that the generator and axia<span>l<\/span> curve relate to each other directly. <span>I<\/span>f you tighten the generator curve the axial curve will open and conversely, if you tighten the axial curve the generator curve will open.<\/h3>\n<h3>Throw the hammer at the metal. Hold the hammer or mallet very loosely at the point of impact or you will pay for the mistake with your body (elbow and other joint pain). This work can be very hard on your body. Take care of it!
