2 2013 TECHNICL DRFTING PROJECT Te following is excerpted from te Contest Descriptions on te SkillsUS website: Tis contest evaluates contestant's preparation for employment and recognizes outstanding students for excellence and professionalism in te field of tecnical drafting. Te contest will focus on te solution of industry-developed problems by applying appropriate tecnical drafting skills and tools including computer-aided drafting (CD). Te project tis year is a attle Top toy sown on tis page. Te Top Housing is sown clear yellow to provide an internal view. Te mecanism is an extremely effective metod for applying spin to a top. Wen two or more tops (it is sold wit tree tops) bump into eac oter wile spinning tey separate very quickly wit sometimes unpredictable results. Te Top ssembly is attaced to te Trigger and ten turned wic builds potential energy in te Trigger Spring via a ratcet connection. Wen te Trigger is depressed, te Top is ejected wic releases te stored spring energy. Project prepared by: Patrick McCuistion Oio University

3 TTLE TOPS Te first tree drawings in tis package sow te parts of te Top. Te remaining parts are sown after te Top ssembly page. Te instructions are to draw te following: 3D geometry for all te parts, fully dimensioned detail drawings of te parts listed in te parts lists except te screw and springs, te TOP assembly drawing including item balloons and parts lists and FINL assembly drawing including item balloons and parts lists. Te detail and assembly drawings must be on proper drawing formats and include completed title blocks. Except for te Screws and Springs, all te parts are injected using ig impact polystyrene.
