This is a precision jig that requires care and attention to get the best from it.
•
Do Not Over Tighten Screws
•
Do Not Use Hammers or metallic objects to move stiff parts
•
Keep Lightly Lubricated
See below for Details.
Unpacking and Assembly
The Box should Contain:-
1. The Master Chassis Jig
2. 1 x 3mm Allen Key.
3. 1 x 2.5mm Allen Key.
4. 3 or 5 Rolling Road Assemblies (Depending on Model)
5. 1 length of each Black & Red Wire to connect to Power Supply.
6. 1 Black Crocodile Clip
7. 3 or 5 Red Crocodile Clips (Depending on Model)
(Item 4 to 7 would be omitted if you requested no rolling roads)
To assemble the connecting wires, remove the rubber boots from the crocodile clips, solder a
short length of the relevant colour of wire through the hole provided and replace the rubber boot.
Starting to Use the Master Chassis
Before use every time coat the 3/5 mock axles and slide rods with either a thin coat of light oil (3
in 1 or similar) or Vaseline. This will prevent any solder used in the assembly of your locomotive
chassis sticking to the jig and stop any flux from attacking the precision steel rods. As the mock
axles and slide rods are made of ground steel, it is also a good idea to repeat when finished to
prevent rust from forming due to either flux or damp. These rods and holes are very precise and
sometimes may be a little tight, rubbing with 600 wet & dry is acceptable to make them slide in a
little easier, but an accurate fit is important.
Locomotive Chassis Construction
There are 3 main factors that must be correct for a chassis to work.
•
Wheel and coupling rod centres must be exactly the same
•
Axles parallel in the vertical plane
•
Axles parallel in the horizontal plane

- Page 2 • It is very difficult to change any of these after construction, but it is also difficult to change the centres of the holes in the coupling rods. You can make the holes bigger but this introduces slop into the system. Slide the Mock Axles into the support blocks with the spigot outermost so that they protrude by the spigot only and lightly clamp using the Hex Allen key in the screws on the top.
- Page 3 We also run regular workshops on Chassis Construction, if you feel as if you need personal tuition in using The Master Chassis or Chassis Construction. Check our website for regular Railway Modelling Workshops with ‘Famous Names’. In the past these have been very sociable events, with good food and company.
