Abstract: A woodworking circle-drawing tool is an apparatus that enables the user to draw precise circles for an axe throwing target. The apparatus includes a support bar, a releasable anchor, a marker holder, a holder clamp, and a small-target stencil. The support bar serves to support the operation of the releasable anchor, the marker holder, and the small-target stencil. The support bar also serves to keep the marker holder at different distances from the releasable anchor to draw the different sized circles. The releasable anchor serves to secure the apparatus to the target board using an appropriate fastener. The holder clamp enables the secure attachment of the marker holder to the support bar. The marker holder enables the attachment of a marker that can be used to draw the target circles using the apparatus. The small-target stencil enables the drawing of smaller circles often found in axe throwing targets.
