So in case of any stronger wind the inner 10-15cm is long enough to resonate and touch the outer tube which made the vibration noise. I fixed these ends with pop rivets to prevent the tubes to touch each other again.<\/p>\n","protected":false},"excerpt":{"rendered":"","protected":false},"author":1,"featured_media":0,"comment_status":"closed","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[5],"tags":[],"_links":{"self":[{"href":"https:\/\/ha3ln.hu\/index.php?rest_route=\/wp\/v2\/posts\/1408"}],"collection":[{"href":"https:\/\/ha3ln.hu\/index.php?rest_route=\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/ha3ln.hu\/index.php?rest_route=\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/ha3ln.hu\/index.php?rest_route=\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/ha3ln.hu\/index.php?rest_route=%2Fwp%2Fv2%2Fcomments&post=1408"}],"version-history":[{"count":12,"href":"https:\/\/ha3ln.hu\/index.php?rest_route=\/wp\/v2\/posts\/1408\/revisions"}],"predecessor-version":[{"id":2430,"href":"https:\/\/ha3ln.hu\/index.php?rest_route=\/wp\/v2\/posts\/1408\/revisions\/2430"}],"wp:attachment":[{"href":"https:\/\/ha3ln.hu\/index.php?rest_route=%2Fwp%2Fv2%2Fmedia&parent=1408"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/ha3ln.hu\/index.php?rest_route=%2Fwp%2Fv2%2Fcategories&post=1408"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/ha3ln.hu\/index.php?rest_route=%2Fwp%2Fv2%2Ftags&post=1408"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
