Drawing a Curve with a Spline

D

RAWING A CURVE WITHa thin wooden spline is an awkward task
for one person to do.You really need one pair of hands to hold
the spline steady and another pair to draw the curve. Here’s how to
draw a curve without having to search for a helper.
Rip a^3 ⁄ 32 -in.-thick spline from^3 ⁄ 4 -in., knot-free stock, about 6 in.
longer than the curve you want to draw. Mark the centerline on the
spline. Make two stop blocks out of scrap stock. Mark the two end
points and the middle apex point of the desired curve on the work-
piece, and attach the two stop blocks at the end points with hot-melt
glue. With one hand, place the spline against the two blocks, and push
it up, aligning the center mark with the apex mark on the workpiece.
Draw the curve with the other hand.
