Therefore, we have adapted a new method: we have found the answer in \u201cvectors.\u201dWhen the force FN(newton) is given vertically against a curved surface, it branches off into f1, f2, and f3.The force f1 and f2 run along straight forward, while f3 runs through the curved surface, thereby causing a crack. (See fig. 1) However, our original global shaped drum shell will disperse the given vertical force along the global surface. (See fig. 2) Hence, we have achieved the desired outcome: a hollowed one-piece drum that is much stronger and more durable than the existing cylindrical surface of the present one-piece drums available.We allow the wood to season naturally for 3years and then treat the shell in a specially designed wood drier to reduce the moisture content down to 9 percent. This drying procedure contributes to minimize the shrinkage and cracking of the drum shell.<\/p>\n<h2>A new revolving height adjustable tubular lug<\/h2>\n<p>The Zelkova drum features a hollowed one piece shell made from a stump of precious 200 years old Zelkova wood. The wood is seasoned for three years and moisture content is regulated down to 9 percent in a specially designed wood drier . However, this shell may still be affected by outside humidity, and may display a degree of contraction and expansion. The diameter of the shell increases when the humidity is high, and decreases when humidity is low.Since commonly used lugs have a  swivel feature to accomodate the tension bolts, it wouldn\u2019t matter if the drum shell expands or contracts. However, the Canopus tube lug has no swivel feature &#8211; it is a solid structure in order to enhance vibration cycle efficiency. Sometimes, when expansion and contraction occurs on the shell, perfect alignment of the tension bolts and lugs may prove difficult  A new revolving height adjustable tubular lug has been designed in order to solve this problem. It has a mechanism which enables the user to adjust at the height of the lug by plus or minus 2mm by simply turning the center pole.<\/p>\n<\/div>\n","protected":false},"excerpt":{"rendered":"","protected":false},"featured_media":14552,"template":"","meta":{"_acf_changed":false,"om_disable_all_campaigns":false,"_exactmetrics_skip_tracking":false,"_exactmetrics_sitenote_active":false,"_exactmetrics_sitenote_note":"","_exactmetrics_sitenote_category":0,"_monsterinsights_skip_tracking":false,"_monsterinsights_sitenote_active":false,"_monsterinsights_sitenote_note":"","_monsterinsights_sitenote_category":0,"_uf_show_specific_survey":0,"_uf_disable_surveys":false},"product_cat":[49],"product_tag":[1414],"class_list":["post-14551","product","type-product","status-publish","has-post-thumbnail","hentry","product_cat-drum-kit","product_tag-zelkova","product-tag-zelkova-drum-set","product_stock-zelkova-drum-set"],"acf":[],"aioseo_notices":[],"_links":{"self":[{"href":"https:\/\/canopusdrums.com\/en\/wp-json\/wp\/v2\/product\/14551","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/canopusdrums.com\/en\/wp-json\/wp\/v2\/product"}],"about":[{"href":"https:\/\/canopusdrums.com\/en\/wp-json\/wp\/v2\/types\/product"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/canopusdrums.com\/en\/wp-json\/wp\/v2\/media\/14552"}],"wp:attachment":[{"href":"https:\/\/canopusdrums.com\/en\/wp-json\/wp\/v2\/media?parent=14551"}],"wp:term":[{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/canopusdrums.com\/en\/wp-json\/wp\/v2\/product_cat?post=14551"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/canopusdrums.com\/en\/wp-json\/wp\/v2\/product_tag?post=14551"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
