When working on furniture I am seldom tempted to scrape softwoods, but it is the best way to go when smoothing the compound curves of the top and graduating its thickness to the tenth of a millimeter. This challenge required upping my scraper sharpening game a bit, so\u00a0 I put on my thinking cap and came up with the solution pictured here, which tells almost the entire story.<\/p>\n<p><a href=\"https:\/\/i0.wp.com\/www.davidfinck.com\/blog\/wp-content\/uploads\/2013\/02\/DSCF4265.jpg\"><img data-recalc-dims=\"1\" decoding=\"async\" loading=\"lazy\" class=\"alignleft size-large wp-image-724\" style=\"border: 2px solid black;\" alt=\"DSCF4265\" src=\"https:\/\/i0.wp.com\/www.davidfinck.com\/blog\/wp-content\/uploads\/2013\/02\/DSCF4265.jpg?resize=640%2C480\" width=\"640\" height=\"480\" srcset=\"https:\/\/i0.wp.com\/www.davidfinck.com\/blog\/wp-content\/uploads\/2013\/02\/DSCF4265.jpg?resize=1024%2C768&amp;ssl=1 1024w, https:\/\/i0.wp.com\/www.davidfinck.com\/blog\/wp-content\/uploads\/2013\/02\/DSCF4265.jpg?resize=300%2C225&amp;ssl=1 300w, https:\/\/i0.wp.com\/www.davidfinck.com\/blog\/wp-content\/uploads\/2013\/02\/DSCF4265.jpg?w=1280&amp;ssl=1 1280w\" sizes=\"auto, (max-width: 640px) 100vw, 640px\" \/><\/a><\/p>\n<p>Nevertheless, I&#8217;ll add a few words to clarify. The small block of 3\/4&#8243;\u00a0 plywood has squared edges. It is captured in my tail-vise along with a fine grit diamond sharpening plate.\u00a0 The wooden block on top of the curved scraper is attached to the scraper with very thin double sticky tape, creating a handle to maneuver the scraper easily. It is now a simple matter to form a nice sharp, square edge on the curved edge of the scraper. I have some ceramic stones that I used next to polish the edge further.\u00a0 I finished off the edge by rubbing some white polishing compound onto a square of MDF, clamping it up like the sharpening stones and buffing the edge of the scraper to a high shine. Before removing the &#8220;handle&#8221; polish the face of the scraper on your finest stones (I use a King 8000 grit water stone). To draw the burr I did most of the work with the burnisher flat on the surface, followed by a very light burnishing on the edge itself to raise a slight burr. This worked very effectively!<\/p>\n<p>By the way, a few weeks ago I was visited by Nancy Malott who came from Kansas to learn plane making.\u00a0 She made a very nice smoother patterned after one of my Dad&#8217;s planes.<a href=\"https:\/\/i0.wp.com\/www.davidfinck.com\/blog\/wp-content\/uploads\/2013\/02\/Nancy-Malott-2.jpg\"><img data-recalc-dims=\"1\" decoding=\"async\" loading=\"lazy\" class=\"alignleft size-full wp-image-726\" style=\"border: 2px solid black;\" alt=\"Nancy Malott 2\" src=\"https:\/\/i0.wp.com\/www.davidfinck.com\/blog\/wp-content\/uploads\/2013\/02\/Nancy-Malott-2.jpg?resize=639%2C887\" width=\"639\" height=\"887\" srcset=\"https:\/\/i0.wp.com\/www.davidfinck.com\/blog\/wp-content\/uploads\/2013\/02\/Nancy-Malott-2.jpg?w=639&amp;ssl=1 639w, https:\/\/i0.wp.com\/www.davidfinck.com\/blog\/wp-content\/uploads\/2013\/02\/Nancy-Malott-2.jpg?resize=216%2C300&amp;ssl=1 216w\" sizes=\"auto, (max-width: 639px) 100vw, 639px\" \/><\/a><\/p>\n<p>In case you are wondering, the tooth brush is used to clear swarf\u00a0 (man, I love that word) from the face of the stone.<\/p>\n<p><em> Until next time!<\/em><br \/>\n<em>df<\/em><\/p>\n","protected":false},"excerpt":{"rendered":"<p>If you follow this blog at all then you know that I recently built a violin.\u00a0 Violin making is a scraper intensive task &#8212; mostly using curved scrapers.\u00a0 The scrapers have to be sharpened quite well to function effectively on &hellip; <a href=\"https:\/\/www.davidfinck.com\/blog\/2013\/02\/27\/sharpening-curved-scrapers\/\">Continue reading <span class=\"meta-nav\">&rarr;<\/span><\/a><\/p>\n","protected":false},"author":3,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"nf_dc_page":"","_jetpack_newsletter_access":"","_jetpack_dont_email_post_to_subs":false,"_jetpack_newsletter_tier_id":0,"_jetpack_memberships_contains_paywalled_content":false,"_jetpack_feature_clip_id":0,"_jetpack_memberships_contains_paid_content":false,"footnotes":"","jetpack_post_was_ever_published":false},"categories":[6],"tags":[],"class_list":["post-722","post","type-post","status-publish","format-standard","hentry","category-miscellany"],"jetpack_featured_media_url":"","jetpack_sharing_enabled":true,"_links":{"self":[{"href":"https:\/\/www.davidfinck.com\/blog\/wp-json\/wp\/v2\/posts\/722","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.davidfinck.com\/blog\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.davidfinck.com\/blog\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.davidfinck.com\/blog\/wp-json\/wp\/v2\/users\/3"}],"replies":[{"embeddable":true,"href":"https:\/\/www.davidfinck.com\/blog\/wp-json\/wp\/v2\/comments?post=722"}],"version-history":[{"count":5,"href":"https:\/\/www.davidfinck.com\/blog\/wp-json\/wp\/v2\/posts\/722\/revisions"}],"predecessor-version":[{"id":733,"href":"https:\/\/www.davidfinck.com\/blog\/wp-json\/wp\/v2\/posts\/722\/revisions\/733"}],"wp:attachment":[{"href":"https:\/\/www.davidfinck.com\/blog\/wp-json\/wp\/v2\/media?parent=722"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.davidfinck.com\/blog\/wp-json\/wp\/v2\/categories?post=722"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.davidfinck.com\/blog\/wp-json\/wp\/v2\/tags?post=722"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
