indispensable piece of equipment when building your own chassis from
brass sheet and tubing is a chassis jig. Chris Briggs is offering the
following jig at a very reasonable price...
The Jig was designed by Dave England and is based on the old (hard to
find) Russkit Adjust-O-Jig. The Jig will be selling for 49.95.. The jig
wheels will be 3/4" for the front at $5.00 a set, and 13/16 for the
rear, also at $5.00 a set. The jig Is fully adjustable from 1" to a full
5 3/4" and is designed to take either 1/8 or 3/32 axles. For using the
3/32 axles you will need to sleeve them with some 3/32 ID brass tubing..
To get the most out of the chassis jig I use a "jig plate" to give
yourself a nice flat surface to lay the chassis parts on, and the jig
plate also sets the ground clearance for the chassis. The one you see here is
make of 1/16" thick aluminum. For my 1/32 scale cars I have the plate
cut to fit between the axle holder uprights, and it is 2 1/2" wide at
the widest point. The slot you see in the rear is for clearance of the
spur gear needed with anglewinder and sidewinder chassis set ups. The jig
plate is not for sale. That is something that you will have to make up
For you new builders here are some tips for using the jig. To set your
motor bracket and keep it in place you will need some brass tubing.
What I do is put the motor bracket with
oilite (bushings) in the jig and
slid it to one side and then measure the gap between the outside oilite
and the side of the axle holder. Then divide that in half and them make
up some spacer like you see in the above picture..
The spacers will keep you motor
bracket centered while you work on the chassis.
The jig wheels are also made of aluminum and are used in place of your
regular tires and wheels to keep them from melting them during construction
Remember patience is key when piecing items together. Take your
time lay everything out on a desk or even a ergonomic desk so you can stand an
work. This will help you keep track of all your parts so you won't lose them
while diligently working.
