The picture shows the impact of low relative humidity on an instrument that was built for a different climate. The prairie winters here in Winnipeg are extremely dry, and for that reason I do all crucial glueing between 30 and 35 % r.H.. Depending on the local climate, luthiers pick an artificial climate that keeps their instruments safe against drying damage. For example, in Germany those values are between 40 and 50 % r.H.. It is obvious that it could be problematic importing an instrument built under such conditions into our dry prairie climate. The reverse is much less dramatic. A &#8220;dry-built&#8221; instrument may not sound its best if it is moved into a humid environment, but its integrity would not be at risk in most cases.<br \/>\nThe lute top in this picture &#8220;potato-chipped&#8221; 4 mm in the center at 36% r.H.. In order to adapt the new top to the local Winnipeg climate, I will glue the braces for the new top at 35 % r.H. or slightly lower.<\/p>\n"},"caption":{"rendered":"<p>Relative Humidity and Bracing <a href=\"https:\/\/www.vorreiterguitars.com\/?attachment_id=578\">Continue reading <span class=\"meta-nav\">&rarr;<\/span><\/a><\/p>\n"},"alt_text":"","media_type":"image","mime_type":"image\/jpeg","media_details":{"width":2816,"height":1872,"file":"2012\/12\/DSC01048.jpg","sizes":{"thumbnail":{"file":"DSC01048-150x150.jpg","width":150,"height":150,"mime_type":"image\/jpeg","source_url":"https:\/\/www.vorreiterguitars.com\/wp-content\/uploads\/2012\/12\/DSC01048-150x150.jpg"},"medium":{"file":"DSC01048-300x199.jpg","width":300,"height":199,"mime_type":"image\/jpeg","source_url":"https:\/\/www.vorreiterguitars.com\/wp-content\/uploads\/2012\/12\/DSC01048-300x199.jpg"},"large":{"file":"DSC01048-1024x680.jpg","width":1024,"height":680,"mime_type":"image\/jpeg","source_url":"https:\/\/www.vorreiterguitars.com\/wp-content\/uploads\/2012\/12\/DSC01048-1024x680.jpg"},"post-thumbnail":{"file":"DSC01048-960x198.jpg","width":960,"height":198,"mime_type":"image\/jpeg","source_url":"https:\/\/www.vorreiterguitars.com\/wp-content\/uploads\/2012\/12\/DSC01048-960x198.jpg"},"full":{"file":"DSC01048.jpg","width":2816,"height":1872,"mime_type":"image\/jpeg","source_url":"https:\/\/www.vorreiterguitars.com\/wp-content\/uploads\/2012\/12\/DSC01048.jpg"}},"image_meta":{"aperture":2.8,"credit":"","camera":"DSC-S600","caption":"","created_timestamp":1360857913,"copyright":"","focal_length":"5.1","iso":"80","shutter_speed":"0.01","title":""}},"post":404,"source_url":"https:\/\/www.vorreiterguitars.com\/wp-content\/uploads\/2012\/12\/DSC01048.jpg","_links":{"self":[{"href":"https:\/\/www.vorreiterguitars.com\/index.php?rest_route=\/wp\/v2\/media\/578","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.vorreiterguitars.com\/index.php?rest_route=\/wp\/v2\/media"}],"about":[{"href":"https:\/\/www.vorreiterguitars.com\/index.php?rest_route=\/wp\/v2\/types\/attachment"}],"author":[{"embeddable":true,"href":"https:\/\/www.vorreiterguitars.com\/index.php?rest_route=\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/www.vorreiterguitars.com\/index.php?rest_route=%2Fwp%2Fv2%2Fcomments&post=578"}],"wp:attached-to":[{"embeddable":true,"post_type":"page","id":404,"href":"https:\/\/www.vorreiterguitars.com\/index.php?rest_route=\/wp\/v2\/pages\/404"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
