Two ways to draw shallow arcs

Creating a regular arc requires tricky calculations or an elaborate .jig, right? Not necessarily. A trio of nails and a strip of wood will do the job. Tack one nail at each endpoint of the arc, and tack the third naii at the apex of the arc, spaced evenly between the endpoints. Cut a thin strip of plywood orhardboard that's at least a Tew inches longer than the length of the arc. Bend the strip between the nails as shown in the above, right photo. Trace along the inside edge of the strip to draw your shallow arc. A variation of this method is simply to insert the wood strip between the jaws of a pipe clamp and tighten the clamp until the strip bows to form an arc of the radius you're seeking (See photo, above left). This method is not as accurate, but it won't leave any nail holes in the workpiece.

Draw perpendicular lines to mark the length and width of the oval. Measuring out from the point of intersection, mark endpomts Tor the length (A, R) and the width (C, D). Set a compass or trammel to draw an arc that's half as long as the length of the oval. With the point of the compass or trammel at one endpoint for the oval width (C or D), scribe hash marks on the length lino (points E, F). Tack nails at points E and F. Tie a string to the nails so the amount of string between the n:iils is the same as the distance from A to F. Pull the string taut with a pencil tip and trace the oval.
