Turnout machines #1030 (kit), #1040 (assm.), #1006 and #1012 (bulk packs). Assembly and mounting instructions. Check parts list. READ ALL INSTRUCTIONS FIRST. Only silicone sealant, plastic model cement and common tools are required. Mark each circle as you complete each step.
Parts list: Base, Motor, I-Beam, Actuating block, Threaded shaft (cut head from screw), Coupling (Silicone), Switch blocks (2-3 parts for each), 4-Leaves (Phosphor bronze), 2-Diodes, 3-3/4" Wire, Linkage rod.
Ol- Place the base in front of you with the motor saddle to the right rear. O2- Affix motor to base with silicone sealant. Note the two slots are toward the rear. With the motor housing flat on the bottom of the saddle, move the motor to the left as far as it will go. Now move it back toward the right about 1/8" - you will feel the shaft end move down in the saddle slightly. O3- Affix I-beam in base slot with plastic model cement - allow to dry. O4- Thread cut end of threaded shaft half way into coupling, then thread shaft half way into actuating block anc slide this assembly onto I-beam and press coupling over motor shaft until threaded shaft meets the motor shaft. Rotate the coupling with thumb and forefinger to center the two shafts. O5- Remove parts from sprue and assemble switches per Fig. #2. Place leaf in groove and put center block over it noting indexing pins. Align parts and "tack" with one drop of cement on one side. Allow to dry. O6- Apply a liberal amount of cement to groove in base, place other leaf in other groove of switch block and insert this assembly in groove in base. Apply more cement to top of switch parts. Repeat for other switch and when inserting into base move the long leaf to the side to clear the other leaf. View from the side to be certain leaves are parallel with the base. Allow to dry. O7- At a point on the two outer leaves about 1/2" from the exposed ends, use long nose pliers and bend the leaf toward the inner leaf to make positive contact. O7- See Fig. #3. Strip insulation from wire ends and solder one end to the + terminal of the motor and insert the other end through the holes in the switch leaves that touch and solder. O8- Bend remaining leaf ends out away from this last solder point. These become solder points #2 and #3. O9- Solder BAND END of one diode to #3 and the other diode to #2 with the BAND AWAY from the leaf. Twist the two remaining diode ends together. O10- Oil motor.
To effect a "live frog" ability (recommended, part #4080 available separately) assemble per Fig. #4. These leaves remain "open" - not touching.
Mounting: There are many different ways to mount these machines. They may be above or below the layout
Above the layout -direct: Note example #3/Affix a 1/2" length of K & S brass tubing about 1" from, and in lini with, the tie bar. Allow to dry - thoroughly. Drill 1/16" hole near end of tie bar. Insert the linkage rod into the tubing until it touches the tie bar. Using long nose pliers, hold 3/16" from end and bend up, making an "L". Now bend 1/16" of the end of the rod toward the stock rail, forming (like) a "Z". Hold the other end of the rod 1/4" from the tubing and bend up until this end is 1" above the mounting surface. Be certain these three bends are aligned. Bend a 1/8" "U" on this end - 90° from the first three bends. Position the machine (with the actuating block at the center of the threaded shaft) parallel to the tangent rails of the turnout and placed so that you can insert the "U" portion of the rod through the hole in the actuating block. Now close the "U", forming a circle and leaving some slack. Temporarily connect power to the machine per Fig. #3 and actuate the SPDT several times. Bend the two INNER leaves OUT to be certain the actuating block has full travel on the threaded shaft. Note that the tie bar does not move. Viewed from above, start rotating the machine small amounts while actuating it. Note the tie bar start to move. Keep rotating until the point rails contact the stock rails in both positions - you may also need to move the machine closer to or farther from the turnout. When optimum operation is attained, mark the outline of the machine on the mounting surface and remove the electrical connections. Holding the machine in the marked position, insert two #4 wood screws in the mounting holes to within 1/8" of the base. Temporarily hold the base away from the mounting surface about 1/8" and inject "dime size portions of silicone sealant beneath the corners, forming "motor mounts" (for even more quiet operation). Allow to dry overnight and remove the temporary spacers and screws. Drill holes for wiring through the mounting surface and upon final electrical connection, bend brass rod for minor adjustments, if necessary.
Using this method, machines may be mounted as far as 6' away by using brass tubing guides about every six inches and even under other tracks and turnouts. They may be concealed by structures, foliage or scenery.
Belowlayout: Bend rod per template. Drill 1/16" hole 5/16" from center of tie bar through roadbed on the frog side and centered between the rails. Insert 1" length of K&S #125 brass tubing down to flush with top of ties and affix from below. Drill 1/16" hole in center of tie bar. Insert rod from above. Center point rails between stock rails with spacers(round toothpicks). Hold in place with masking tape. With the actuating block centered, determine a convenient place for the machine below the layout 1/2" from the rod and aligned with the actuating block - mark the two mounting holes. Remove the machine and start the holes with #4 wood screws. Now mount the machine with the two screws up to 1/8" from layout. Temporarily use spacers to hold machine parallel with surface and inject "dime" size amounts of silicone sealant beneath each corner. Allow to dry overnight. Remove spacers and screws. Bend rod at 90° toward actuating block per example 1. With long nose pliers, hold rod at a point about 1/4" past the pin and form a "U" around the pin and remove any excess. Remove the tape and spacers from above. Make minor adjustments by bending the brass rod. This linkage method at the turnout may be used to have ONE machine actuate a crossover and even a double crossover.
Power Supply: Note Fig. #3. Use Radio Shack transformer #273-1352 or NT TX121 and resistors #271-132 or NT R10X10 (mount side-by-side, connect in "parallel"). Solder diodes to the SPDT switch and mount in a convenient location. Using 18 AWG wire, connect transformer to diodes on the SPDT, connect the center post of the SPDT to the diodes on the machine, connect remaining motor tab (point #1) to the resistors and the resistors to the remaining transformer lead. Create a "bus" by connecting point #1 to all other motors and another "bus" by connecting a transformer lead to the diodes on all other SPDTs.
Additional notes: To add trackside signals using LED's, connect from #1 to #2 for one direction and #1 to #3 for the other direction. For panel indicators, connect from #4 to #5 for one direction and #4 to #6 for the other.
