TJ R1 /
The [ Truck
Jig ] is a tool designed to hold the Central Valley freight car truck bolster.
This allows you to drill out the boss to the needed diameter.
I suggest using a “Pin Vise” and drill them by hand so you do not destroy the truck.
Most freight
cars have 1/8th inch bolster king-pins and need a 0.1285” bore (#30
drill bit) in the trucks.
Mantua
freight cars with a metal under-frame have 9/64th king-pins and
require 0.147” boss (#26 drill bit) in the trucks.
The Jig was originally conceived to hold Central Valley trucks, but it fits most (2 axle) freight car trucks, although some have to be upside-down.
Kadee trucks will not fit this tool. The [ TJ V2 ] will fit Kadee trucks.
The center
void extends all the way through the jig.
The mounting holes will accommodate a #6 screw to attach the truck jig to a piece of wood or bench top.
The two freight cars are Mantua cars with a metal chassis (9/64th king pin) and Accurail trucks installed
