The grain in the nut block is perpendicular to the jaws because the nut block gets tenoned into the base. They are a two piece lamination to get the necessary thickness. Finger jointed I would say because its less fussy to produce with a better glue joint in a production setting than a butt joint, but that's just a theory. I would imaging they had a dedicated shaper set up for finger jointing in the factory, and used the joint on many things, not just the miter jack. They would probably run long blanks (several feet) through the shaper, glue that up, then slice off jaws for miter jacks from that one blank. That would be the way to do it in a factory setting. These things weren't made by hand all that much, since it takes machinery to cut the finger joint, and a particularly heavy machine to do ones of this size.

Even if there is no direction change, why is it systematically in two pieces while the part used as the nut for the screw is in one piece? Are the two pieces of the same wood specie?<br />The two pieces feature is visible in the catalog. There must be a good reason.<br />SylvainAnonymousnoreply@blogger.comtag:blogger.com,1999:blog-2430989134966768004.post-63744745490692677252015-05-25T12:05:18.577-05:002015-05-25T12:05:18.577-05:00More glue surface.

The two pieces chops allow a change in grain direction near the tip and might be done to avoid splitting. Just an hypothesis.<br />SylvainAnonymousnoreply@blogger.com
