PLEASE READ INSTRUCTIONS THOROUGHLY BEFORE COMMENCING ASSEMBLY
CONSTRUCTION
ASSEMBLY
It is important to ensure that all parts are clean, free of "flash" (excess metal on castings) and fit properly. The "flash
line" is easily removed from most areas by scraping gently with a sharp hobby knife - a round blade is more effective
than a straight pointed type. Pull the blade along the "flash line" - several light strokes are better than a single one. Some
areas are better cleaned up with 6" jewellers' files. Take care not to flatten round parts by filing too heavily. All locating
holes for detail fittings should be pre-drilled to the size specified in the instructions. Sometimes it is necessary to clean
out these holes with a "rat tail" file; take care not to snap off the tip of the file. Gently wash the castings in warm soapy
water to remove mould release residue.
Etched brass items are best removed from the fret by placing the fret on a scrap piece of timber (e.g. Pyneboard) and
cutting the tabs with a large Stanley knife - cut the tab at the point furthest away from the part, then trim the tab off close
to the part with a small pair of quality side cutters. Hold small etched parts with a pair of flat nosed (not serrated jaws)
pliers while cleaning up with jewellers "files. Be careful not to distort the etchings; they are difficult to straighten if bent
or twisted. Drill all required holes before assembly, noting the sizes shown on the drawing, because some holes will be
difficult to drill after parts are assembled.
As with all classes of NSWGR locomotives, individual D57s varied in minor details from time to time in their life.
Unfortunately the Data Sheet's plan of the D57 is currently out of print, however good photos and a side elevation plan
are contained in Ken Groves' excellent book "The Big Engines". Alex Grunbach's book "Compendium of Steam" in
particular contains a very good section on the D57, complete with photos showing identification of parts.
Modellers are advised to check photographs of the particular locomotive they have chosen to model, also keeping in
mind the era they are modelling.
These kits are designed to give many years of operating pleasure. A little extra time taken during construction will
ensure that your kit will do this. It cannot be emphasised too strongly that the basis of a smoothly operating model is
care when constructing the chassis and valve gear, i.e. you must double check every step. Check that the axles turn
freely in their bearings, check again with the side rods on, then again with the connecting rods on, etc, etc.
Assembly methods
The two main construction methods are:
(a) Low melt solder - Low melt solder is an excellent medium for use with white metal kits. It is quick and easy
providing a stronger joint than can be achieved with glue. It has the added advantage of easily repairing minor casting
flaws, and because of the relatively low temperature, many parts can be held in the fingers while soldering. Brass to
white metal joints can also be made by "tinning" the brass first with normal solder. Low melt soldering requires the
correct type of soldering iron (e.g. Dick Smith T2200). These irons have temperature control, as low melt solder
requires temperature between 70 degrees and 200 degrees Centigrade. You should use special low melting point solder,
such as that available from AR Kits.
