In the meantime, however, let us consider some ways to improve this ubiquitous woodworking task. The uncommon tips in these posts <strong>apply not only to hand sawing<\/strong>,<strong> but also machine sawing<\/strong> without a fence such as might be done with the bandsaw.<\/span><\/p>\n<p align=\"JUSTIFY\"><span style=\"color: #000000;\"><strong>We know the basics:<\/strong> an appropriately designed, good quality saw, straight, properly sharpened and set. The work piece is securely held in an ergonomic position. The sawyer grips the saw properly with good hand-shoulder alignment, and produces even strokes engaging the length of the saw.<\/span><\/p>\n<p align=\"JUSTIFY\"><strong><span style=\"color: #000000;\">Tip #1: Consider the line and what it means.<\/span><\/strong><\/p>\n<p align=\"JUSTIFY\"><span style=\"color: #000000;\">The idea here is to have <strong>mental clarity<\/strong> as to just what the line represents and thus how you will saw in relationship to it. <strong>Mental clarity precedes physical success.<\/strong> <\/span><\/p>\n<p align=\"JUSTIFY\"><strong><span style=\"color: #000000;\">Consider several scenarios.<\/span><\/strong><\/p>\n<p align=\"JUSTIFY\"><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter size-full wp-image-1623\" title=\"IMG_0586_edited-2\" src=\"https:\/\/www.rpwoodwork.com\/blog\/wp-content\/uploads\/2012\/04\/IMG_0586_edited-2.jpg\" alt=\"\" width=\"510\" height=\"339\" \/><\/p>\n<p align=\"JUSTIFY\">If the line is produced by <strong>drawing against a template<\/strong> as in, for example, sawing curved legs from rectangular blanks with the bandsaw, then the entire line is in the waste wood. If you split the line with the saw, there remains a half-line of extra wood to remove saw marks and fair the curve. If you want more margin for clean up, make a chunky line and saw right up to it without touching it. The key is to be clear about <strong>what you are aiming for and why.<\/strong><\/p>\n<p align=\"JUSTIFY\"><span style=\"color: #000000;\">If you use a pencil to<strong> mark out pins from the tails<\/strong> you&#8217;ve sawn, <strong>the line is fully in keeper wood.<\/strong> If you split this line, the pins will surely be too small. If you saw to one side of it, and no more, things should work out fine.<\/span><\/p>\n<p align=\"JUSTIFY\"><span style=\"color: #000000;\"><strong>If a part is marked to length<\/strong> by registering it with the end of another part which is thus used as a template, the line will be fully in waste wood. Splitting it with the saw will make the resulting piece too long, but perhaps this is a desired allowance to allow for shooting it just right. Sawing to <strong>fully remove the line<\/strong> would be an attempt to produce an exact match from the saw. Again, the <strong>intent<\/strong> should be thought out beforehand.<\/span><\/p>\n<p align=\"JUSTIFY\"><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter size-full wp-image-1624\" title=\"IMG_0585_edited-2\" src=\"https:\/\/www.rpwoodwork.com\/blog\/wp-content\/uploads\/2012\/04\/IMG_0585_edited-2.jpg\" alt=\"\" width=\"510\" height=\"367\" \/><\/p>\n<p align=\"JUSTIFY\"><span style=\"color: #000000;\"><strong>As another example,<\/strong> I set my mortise gauge so the two points are at exactly the width of the mortise and mark out the tenon with this setting. I run a pencil line so the point rubs against both sides of the &#8220;valley&#8221; of the scribed line. I then know that if I <strong><em>split<\/em> this line<\/strong> with my saw, the tenon will be just right.<\/span><\/p>\n<p align=\"JUSTIFY\"><span style=\"color: #000000;\"><strong>Visually, I find it easiest to split a line with the saw.<\/strong> The visual cue is that as the cut proceeds I can see half of the line remains next to the kerf, and this remainder looks half as wide (easy to estimate) as the uncut line ahead. When <strong>sawing to one side of a line,<\/strong> it is easy to be too timid and leave extra wood, though if this is not excessive it may work out fine, allowing for a bit of clean up. <strong>Sawing to completely remove a line,<\/strong> but no further, is visually difficult since the result looks the same if you have done it just right or if you have sawn too far into the keeper wood.<\/span><\/p>\n<p align=\"JUSTIFY\"><span style=\"color: #000000;\"><strong>The key is to be clear about the &#8220;context&#8221; of the line and anticipate the next step in construction.<\/strong> In all of these matters, the concept of <a href=\"https:\/\/www.rpwoodwork.com\/blog\/2010\/12\/11\/one-sided-tolerance\/\" target=\"_blank\">one-sided tolerance<\/a> is most helpful.<\/span><\/p>\n","protected":false},"excerpt":{"rendered":"<p>All would be right in the world of woodworking if we could saw perfectly to the line every time.
