4. A Step-by-Step Guide to Tangent Handrailing
Tangent handrailing involves a series of precise steps, from drafting the initial plan to shaping and molding the final handrail. CONDUCT.EDU.VN provides a detailed, step-by-step guide to help you navigate this intricate process.
4.1. Drafting the Plan
The first step in tangent handrailing is creating a detailed plan of the handrail fitting. This involves drawing the handrail in plan view, elevation view, and oblique plane.
Step 1: Draw two intersecting lines that are perpendicular to one another. Label their intersection point A.
Step 2: Create a square box to represent the plan view of the handrail by drawing lines parallel to both the horizontal and vertical lines. The distance of the offset is the centerline radius of the handrail turn in plan, 5 inches in this example. Note that the parallel vertical line should also project above the horizontal line.
Step 3: Use a compass to draw the centerline of the handrail’s curve in plan. Point C in the drawing (below) is the center of the arc, and the compass is spread to the predetermined radius distance of 5 inches. With the arc drawn, the tangent and spring lines can be identified.
Step 4: Measure out along the horizontal line from point V (the vertex), using the same radius distance used previously (5 inches) to locate point B1. From this point, use a protractor to draw a pitch line at the angle of the stair pitch, 35 degrees in this example. This creates an elevation view of the three dimensional box being drawn.
Step 5: Use a square to draw a line perpendicular to the pitch line that intersects point V.
Step 6: Locate point Bo by swinging an arc from point Vo, with the compass spread to the distance between Vo and B1.
Step 7: Draw a line originating at point Vo that passes through point Bo to define the inclined tangents.
Step 8: Create the parallelogram that makes up the oblique plane (the lid of the box) by drawing lines from points Ao and Bo that are parallel to the inclined tangents.
Step 9: The next step is to determine the bevel angle for the handrail. This is the angle where the handrail’s profile is ‘twisted’ at each end in order to match the profile of the straight raking rails. Using point V as a center, spread the compass until it touches the intersection of the pitch line and the perpendicular line drawn in step 5, and then swing an arc to the base line.
Step 10: Draw the bevel line by connecting the arc intersection on the base line to point B. This line represents the centerline of the handrail profile.
Step 11: Begin creating a box that will encompass the handrail profile by drawing lines parallel to the bevel line. Since the handrail width in this example is 2 1/2 in., the offset is 1 1/4 in. on each side of the bevel line.
Step 12: Finish the box that surrounds the handrail profile by drawing two lines perpendicular to the bevel line to define the height of the profile. In this example, the handrail profile is 1 3/4 in. tall.
Step 13: To determine the minimum required stock size for the wreath block, enclose the squared profile box with a box that is square to the level base line.
Step 14: With the squared handrail profile determined, it’s time to move back to the oblique plane and the creation of the face mold. The inclined tangent lines that extend outside points Bo and Ao represent the centerline of the ‘shanks,’ or straight sections, on either side of the curved portion of the fitting. The widths of the shanks on the face mold are determined by the squared handrail profile and the bevel angle. Use the distance measured along the base line, from the bevel line intersection to the handrail width line intersection, to offset each side of the shank center line. Finish by squaring off the shanks with a perpendicular line; the shank length is arbitrary.
Step 15: Draw ordinate lines for the plan view and oblique plane by drawing lines connecting points C and V, and points Co and Vo.
Step 16: Draw the inner and outer edges of the handrail in plan by drawing arcs centered on point C, offset from the plan centerline by 1/2 of the handrail’s width on each side. The distance is 1 1/4 in. in this example for the 2 1/2 in. wide handrail.
Step 17: Draw a line parallel to the ordinate line in plan. The distance is arbitrary; it will be used as a benchmark for projecting measurements to the oblique plane.
Step 18: Draw a line from the intersection of the previously drawn parallel ordinate line and the tangent line, parallel to the height line, until it intersects the inclined tangent line above.
Step 19: Transfer the intersection point on the inclined tangent line to the opposite inclined tangent line by using a compass to swing an arc centered on point Vo.
Step 20: Draw lines from both points on the inclined tangent lines that are parallel to the ordinate line of the oblique plane.
Step 21: Begin transferring measurements from plan to the oblique plane. Use the distance along the ordinate line in plan from point V to the handrail’s inner edge (Red) to mark point 1 along the oblique ordinate line from point Vo. Use the distance along the parallel benchmark ordinate line in plan, measured from the tangent line to the handrail’s inner edge (Blue) to mark points 2 and 3 up from the inclined tangents, along the lines drawn parallel to the oblique ordinate.
Step 22: Transfer the handrail widths from plan to the oblique plane. Mark point 4 along the oblique ordinate line measuring down from point 1, which is the handrail width along the ordinate line in plan (Red). Mark points 5 and 6 by using the distance measured from the inner to outer handrail edges along the benchmark ordinate line in plan (Blue).
Step 23: Complete the face mold by using a flexible curve to connect points 1, 2, and 3 to the inner edges of the shanks, and points 4, 5, and 6 to the outer edges of the shanks.
4.2. Creating the Face Mold
Once the drawing is complete, you can create the face mold. This template will guide you in shaping the handrail from the wood blank.
4.3. Shaping the Wreath
Using the face mold as a guide, carefully cut and shape the wreath from the wood blank. This involves removing excess material with a bandsaw, refining the curves with a spokeshave, and smoothing the surface with a rasp.
4.4. Molding the Wreath
The final step is molding the handrail profile. This can be done using a variety of tools, including hand-held routers, grinders, or traditional carving tools.
