ay-oul tools arc woodworking's widows a rvd orphans. The work I hey do serins pretty mundane, so we woodworkers tend to focus our attention and ourexpendilureson the fancy stuff. The shift in focus from hand work and hand joinery to woodworking machines played a part in the demotion of layout tools, as a lot of layout is now built into the fences and guides on machines.
Just as no shop docng quality woodworking will ever get completely away from hand work, we are unlikely to ever eliminate the need for layout tools. If you are a woodworker you do need to ownand know how to use layout tools. Fortunately, they are not hard to figure out. Theyarejustabit foreign for some of us.
layout tools usually come into play early in the furniture-making process. Generally, the only work you do before layout is stock preparation. Before anyjoiningor shaping is done, your stock will have to be laid out.

That would be the ideal in woodworking; bui what we can imagine we cannot alwayscreaie. Any line we make has width. Cut slightly to one side of a line in one pltce and to the other side in anot her. and you can be off by the wklthofthat line. This may not seem like a lot. but a shoukler or dovetail with a gap thai wide is pretty obvious.
A pencil draws a line and no matter how sharp the pencil, its line has width. For this reason, woodworkers usually rely on scored. ratherihandrawn.LiyxxH lines. Inwoodwotk-ing. scoringthese lines iscommonly referred
