Honzík trains Blog Archive T 466.2 "Puss' N scale - building drive
On the modeling market is to get a quality etching diesel locomotive 742, formerly T466.2, which became known as the Cat. As with all models in N scale (unfortunately not on this scale) is a fundamental problem hanging in the balance in the construction of model drive, respectively. the whole travel. In this case, I did not want to invent a completely hanging in the balance new ride. A friend advised me that could possibly put to use travel of American machine into SW-8, esp. Because the spacing of axles and chassis are the same. And so it happened. 1)
The aforementioned model locomotives SW-8 Although made in China, which is seen, for example. Slightly šmajdajících wheels, but the engine is on the contrary very good, 5-pole. It also transfers are well chosen for a slow ride. Using these components can be manufactured quite easily travel to the etching model locomotive T466.2. I believe that it can handle even moderately experienced modeler. You only need to accurately measure and work with maximum precision. In the following lines I mention not accurate guidance on the status of model locomotives, but only a description of how I made travel alone. Maybe it will help someone to build your own model. I note that I will not describe the construction of etching. I refer to the manufacturer's assembly instructions ... (but it is very brief and without sufficient experience in dealing with etchings body can build locomotives be inexperienced modelers problems - ed. Red. JH). However, I point to some of the adjustments that I had to do was to assemble the locomotive body with that of a locomotive traveling SW-eighth Everything is for illustrative documented in photographs.
As the motherboard I used commonly available cuprextit (tl. 1.6 mm) used for the production hanging in the balance of printed circuit boards. hanging in the balance I recommend cuprextit plated copper layer on both sides - for strength - but it is also possible to use commercially available single-sided cuprextit. In this case, the copper layer at the bottom. First, hanging in the balance measure the frame etching and these rates Plot outline on the board cuprextit. After two long sides of the measured size is reduced by about 1 mm, because there extends from the bottom hanging in the balance of the frame rail. Also shorten the length for installation couplers and stairs (Fig. 1-2).
On the bottom side, cut exactly in half the copper layer over the entire hanging in the balance length for example. Razor saw, which create two symmetrical halves isolated travel for the distribution and collection of the current (seen in Fig. 3).
On the top side of the outlines of the center mark and on the pitch rozměříme chassis. I recommend spacing of 1 mm smaller so that the chassis curves hanging in the balance from getting trapped in the stairs! And precisely drilled holes we perfect chassis to chassis in openings slightly rotated, but without clearance. hanging in the balance The longitudinal axis of the plate, hanging in the balance in each hole, are 2 times propilovány notches about 2 x 1 mm for inserting hanging in the balance the chassis and its rotation into the correct position (Fig. 4). Against the chassis falling on it two locking lugs. The chassis is in the original frame established in the metal riser 2.5 mm thick. Since cuprextit plate is 1.6 mm thick, it must be in its original size (2.5 mm) to add material. I solved it so I'm at the bottom of the frame on both sides of the openings naletoval tapes brass sheet strength hanging in the balance 0,5 mm, which I dopiloval the hole. This chassis has enough clearance to move and in addition there is also enough space for movement of current collectors. From the upper side panels hanging in the balance are soldered- hanging in the balance tape only 0.3 mm thick sheet. Place the sheet but you can stick (from both sides) strips of plastic suitable strength. As mentioned above, the tape must be at bonding (brazing) to intervene hanging in the balance into the hole where exactly zapilují hanging in the balance with the edge of the hole. After insertion of the chassis should be clearance for its movement to a height of about 0.1 mm to 0.2 mm. This is so that when the screw lifting frame got out of engagement with the gear.
In the next phase of construction drive is needed to pursue the perfect hanging in the balance storage hanging in the balance engine. It is necessary to demarcate the exact position for placing the motor in the base plate, cut a hole slightly smaller, and this gradually dopilovávat so that the engine went natlačit into the hole so. Tight (Fig. 4 and 5).
Motor must abut exactly, but with little play in snails gears. It is best to wrap around the screw piece enamelled wire with a diameter of 0.3 mm, which after fitting hanging in the balance the motor unwinds again - it will remain correct. The engine is still - except the exact fit - retained (on the side of the collector with the carbons) copper wire with 0.5 mm stitch namotaným as the carbon hanging in the balance holder, which is on the underside hanging in the balance of the plate soldered to one half of the circuit. From the upper bracket carbon wire is pulled through the bottom of the pack boards propilovaným notch (or hole) and soldered on the other half of the plate. On the other side of the motor is supported by bearings in place of Pliska or plastic with vypilovaným bend, to shift into engagement gear (Fig. 5). (Note .: author describes the arrangements for analog operation of locomotives in the case of digitization will be mainly fixing and connecting the motor to the other decoder - note. JH) from the original frame to take off their American locomotives current collector sheets pomo
