c urved point rai l w i t h the N M R A gauge. Bend the rail again until this dimension i s perfect. Then solder t h e curved point rail to the floating ties. For my manual method of turnout con trol, bend the throw-mechan i s m rod over and solder it to the f irst floating tie. Other methods of control w i l l need other attach ment procedures. Photo 37 shows the mech anism from the underside of the turnout. The rubber band provi des the p o s i t i ve l o c k ! Since the frog i s not insulated, track power is supplied via a microswitch thrown by the turnout mechanism (see Photo 38). The frog feeder wire attaches to the "pole" of the microswitch and the p l u s and m i n u s track power attach to the appropriate two "throws" of the microswitch. Finish the turnout by painting the pc board ties with an appropriate color. I like to use a 50-50 mixture of Floquil Engine B lack and Rust. Weather these ties and other wooden ties to disg u i se the d i fferent tie materia l s . Apply ballast around t h e turnout, keeping the grains off the tie tops. Apply some plastic compatible oil around all the floating ties, the pivot point and the turnout mechanism. Then glue the ballast in place using the traditional "bonded b a l l ast" technique often used b y most model rai l roaders . Another p i nch o f powered graphite will help loosen any sticky points after the ballast glue has dried. Finally, clean off the rai I tops to remove the weather ing patina and any stray paint with a rail bur nishing block and you're done. With a l l the component rail s in p l ace (Photo 39), the fi n ished handlaid turnout l OOKS b eau t ifu l . B y fol lo w i n g t e m p l a t e s , using p c board ties and checking with gauges, the turnout operates as wel l as it looks, too. HandJaying tu rn o u t s in code 40 r a i l for N scale can be fun and rewarding.
