Building a Base Table for Your LayoutA sturdy walk-around base table is the best foundation you can give a model-railroad layout. Model railroaders Dave and Alex Caplan explain the basics.
Materials:
10 pieces 1" x 3" x 8' pine, #2 grade
Three pieces 1" x 2" x 8' pine, #1 grade
Four pieces 1" x 3" x 6' pine, #1 grade
Two pieces 1" x 4" x 10' pine, #1 grade
Two pieces 1" x 4" x 6' pine, #1 grade (for end sides of table)
1/4" x 4' x 8' sheet of plywood
#6-size 1 1/4" Phillips-head screws
Power drill
Power screwdriver or combination drill/screwdriver
Hand saw or power saw
Paint or stain
1.
The outer dimensions of this table will be 8' long by 4' wide. Begin by selecting two 1" by 3" by 8' pieces of #2-grade pine for the 8' outer edges. Next, select four 1" by 3" by 8' pieces of #2-grade pine for outer frame width and inner support pieces. These four 8' lengths should be cut into seven 46 1/2 " pieces -- for the five inner pieces and the two outer (leaving one extra length). Drill holes in the ends of the 8' lengths and attach a 46 1/2" piece to each end, screwing it into place. Working from the outside in, screw a 46 1/2" piece 17" from the end; repeat for other end. Screw another 46 1/2" length into place 17" from the last one, and repeat for other end. Finally, the two center pieces -- which will provide the greatest support -- should be measured and screwed into place at approximately 11 3/8" from the most recently placed two pieces.
Tip: When cutting the inner cross supports, the 17" pieces can range from 17" to 17 1/4". Measure and cut pieces accordingly. A total of six 17" cross supports and three 11 3/8" cross supports are needed. Screw these cross supports in place to support the 46 1/2" lengths (figure A). Countersink screw holes for a smooth, finished look.
2. Cut four pieces of 1" by 3" by 6' #1-grade pine to eight 36" pieces to create the legs. The legs are built by placing two pieces of cut pine perpendicular at the edges (figure B), in an L shape. Secure the boards with wood screws approximately 6" apart. Countersink the screws, and fill with wood putty, then sand the legs to a smooth finish. The legs are now ready to be stained or painted, as you like.
3. Attach the legs inside the corners with five 1 1/4" screws, securing the legs on the 4' and 8' sides. Make sure the tops of the legs are flush with the top edge of the frame so the plywood will lie flat on the frame. Screw each of the four legs to the base table framework at the four corners. Attach cross supports of 1" by 2" by 93" pine from the inside bottom of the 8' frame to the side of the leg approximately 18" above the floor with one 1 1/4" screw on each end. Follow these steps on both sides of the table. Attach cross supports of 1" by 2" by 45" pine from the inside bottom of the 4' frame to the other side of the leg approximately 18" from the floor. This will give the table stability and strength. Measure the exact length of the 8' side of the table, and cut a piece of 1" by 4" by 10' pine to the measurement. Repeat for the 4' side of the table. Finish the table by attaching the cut pieces of 1" by 4" by 10' pine with 1 1/4" screws. If you want a smooth finish for painting or staining, countersink the holes, and fill with wood plugs or wood putty. Paint or stain the outer frame to match the legs.
4. Place a 4' by 8' by 1/4" sheet of plywood on the completed frame. Drill countersunk pilot holes around the outside edge of the plywood, making certain to drill into the frame (figure C). Secure the plywood to the frame with screws at approximately 10" intervals, countersinking the screws to create a smooth surface for the train.
Laying the Groundwork and Making a Track PlanProper preparation of your layout will facilitate smooth operation of the train. Model railroaders Bud German and Kent McBee explain proper preparation techniques.
Materials:
4' x 8' sheet of residential insulation foam board
Low-temperature glue gun and glue sticks
8 1/2" x 11" sheet of notebook paper
Black marker
Pencil
Straightedge or wooden yardstick
Power drill
Tape measure
Piece of switch track
1. Drill a hole large enough for a pencil to pass through 2" from one end of the straightedge or yardstick. Measuring from the inside edge of the hole, use a marker to mark spots at 18", 20" and 22". Drill holes at the marks large enough for the marker tip to pass through. (The measurements represent the most common radiuses used in model railroading. Radius is always measured from the center point of the lines, between the rails.) Set the straightedge or yardstick aside.
2. Place a 4' by 8' piece of StyrofoamB. insulation board on top of the plywood table, but don't secure it to the table. If you make a mistake, you'll be able to replace the inexpensive foam board without replacing the plywood. Draw a large oval on an 8 1/2" by 11" piece of notebook paper. To make the layout look more realistic, draw industrial spurs -- sections of track that extend off the main track to give rail access to industrial plants and loading areas (figure D) -- at each end of the oval. And in case you'd like to add to the layout in future, draw additional spurs at each end of the completed oval (figure E).
3. To transfer the hand-drawn layout to the foam board, you must find the focal point at each end of the table. Measure and mark 24" in from the 4' end of the table. Now measure in 24" from the 8' side of the table, and make a mark to intersect with the first mark. The spot at which the two points intersect is the focal point .
4. Place a pencil through the first hole drilled in the straightedge, and put the pencil on the focal point, holding it securely in place. Place a marker through the drilled hole at the 22" mark (figure F), and, using the straightedge as a compass, draw a half-circle with the marker (figure G). Repeat these steps at the other end of the table.
5. Use the straightedge and marker to connect the half-circles with straight lines to create a large oval on the foam board. The lines don't have to be precise, but the radius of the circle must be consistent so the train will track properly. Use the straightedge to extend the side lines past the edge of the half-circle at each end on opposite sides, as with the hand drawing.
6. Place a piece of switch track at every point where the track splits -- where one line completes the oval and another creates a spur. Use a marker to mark the center line of all pieces of track (figure H).
7. Moving about 9" down the track, toward the center of the straight side lines, use the piece of switch track to mark the site of the industrial spurs. Using the piece of switch track as a guide (figure I), draw the spur lines with a black marker. Precision isn't vital -- just draw the line in a tighter radius into the oval.
8. Use a low-temperature glue gun to apply a generous bead of glue around the outside edge of the table. Press the foam board firmly to the plywood, and give the glue a minute to set up.
Laying the RoadbedLaying a roadbed correctly is vital for the smooth operation of your train. Model railroader Jim Davis explain how.
Materials:
10 pieces 36" HO-scale cork roadbed
Hobby saw
Hobby knife
Low-temperature glue gun and glue sticks
1. Cork roadbed is scored and breaks readily. Bend and split a 36" piece of roadbed in half lengthwise to create two thinner pieces (figure J). The center split will create two opposing beveled edges, which, when turned over, create the elevated edges of a roadbed (figure K). By placing the pieces side by side, with the beveled edges out, you can create the roadbed needed for an HO-scale train and have a perfect center line with which to line up the track.
2. It's important to make the roadbed as flat and smooth as possible. Make sure it doesn't begin or end at a joint -- for example, at the switches or where two tracks come together (figure L). Always stagger the ends of the roadbed halves so the joints don't run across the entire roadbed.
3. To hold the roadbed in place, squeeze a bead of glue from a low-temperature glue gun along the center line drawn on the foam board. Secure half of the roadbed carefully along that line. Continue along the curved lines previously drawn, and glue the roadbed on both sides of the center line until you've completed all the lines.
4. After you've laid the roadbed down the spur and around the curve of the oval, you will have created a gap at the V, or switch location. The space must be filled with roadbed. Begin by placing a piece of roadbed over the gap at the switch (figure M). Make certain to follow the curve. Using a hobby saw, score the roadbed using the straight edge of the spur roadbed as a guide. After beginning the cut, move the roadbed piece to a convenient spot to complete the cut with a hobby knife. The resulting piece will fill the gap perfectly (figure N). Glue the piece in place.
5. Complete the entire oval, the spurs and the sidings, using these techniques ( figure O).
Laying Track
Once you begin laying track, the layout begins to look more like a railroad. Model railroader Jim Davis describes the process.
Materials:
10 pieces 36" HO-scale flex track
Four HO-scale switches
One package rail joiners
Rail nippers
Low-temperature glue gun and glue sticks
Push pins
1. Take a rail joiner from the package (figure P) and break off one section. Insert the rail joiner into the end of the flex track (figure Q). Rail joiners keep the rails in line and carry the electrical current needed to power the engine.
2. If there is not enough exposed rail at the end of the track to insert the rail joiner, take rail nippers and loosen the last tie on the end of the flex track. Using your fingers, carefully remove the loosened tie (figure R) to expose more rail to be connected with a rail joiner. Set aside the removed ties.
3. Insert rail joiners, and join the flex track with the switch track. Place the switch on the roadbed at the previously marked location (figure S), and center the flex track over the roadbed's center line.
4. Using a glue gun, tack the switch at the marked location and glue the flex track in place, making sure to center the track over the center line in the roadbed, paying particular attention to centering the track at the curves. Remember to prepare each length of track by removing the last tie at each end. If you don't have an extra pair of hands to help you hold the track in place while the glue dries, use push pins to secure the track to the roadbed while the glue sets up.
5. As the track begins to curve, one rail extends further than the other because of the curve. Using rail nippers (figure T), even the rails before connecting the next piece of track and gluing it down. Continue until the entire track is laid.
6. As you finish laying the track, you'll see gaps at the ties where you've joined rails (figure U). Take the ties you previously removed from each end of the flex track, and slide them under the rails to complete the line.
