hold the object as securely, so check the
cones frequently to make sure they are
tight against the object while balancing.
BALANCING SUGGESTIONS: To
balance a spinner, balance the backplate
first. Mark the light side (up), then
remove material from the heavy side by
drilling several shallow holes in the
backplate. Don’t drill through the
backplate and don’t drill where it will
weaken the structure. Repeat by trial
and error, until the backplate balances
perfectly. If the spinner cone has a front
hole, you can now join the backplate and
the cone on the balancer, to determine
the balance of the cone. To balance the
cone, carefully remove material from the
inside of the cone with a piece of
medium-grit sandpaper, being careful
not to remove so much material in one
place that it would weaken the cone.
NOTE: Spinners that do not have a hole
in the front of the cone do not lend
themselves to balancing, so in this case
just balance the backplate.
How to balance CAR WHEELS: Most
car wheels can be balanced with this
balancer using the method described
above and doing so will make a big
difference in the smoothness and
handling of your car. Certain car wheels
which have large diameter holes (such
as 1/10 scale on-road rear wheels) will
also require the use of an inexpensive
adapter, such as the DuraTrax
®
#DTXC9581 BBS Wheel Adapter
(available from your hobby dealer),
which reduces the center hole to a size
that this balancer can accommodate.
Another way to balance rear on-road
wheels is to mount them to an extra
left
diff side from your model.
When balancing car wheels,
safety is of utmost importance.
Do not attempt to balance car
wheels by sticking pins into the
rubber, as these can come loose.
Also, a spinning wheel with any
protruding metal can be very
hazardous to a person holding the
car. Self-adhesive lead tape works
great for balancing wheels. Check
with your hobby dealer or a golf
supply store for this type of tape.
Consult with your local hobby dealer
and track owner for methods that
are acceptable in your area.
TIPS FOR ULTRA-PRECISION
BALANCING:
If you need to balance small objects
with high precision, such as boat
propellers, you can follow this
procedure to increase the precision of
your balancer:
1. Examine the balancer shaft ends
with a magnifying glass. The shaft ends
should be concentric with the shaft
centerline and should not be blunt or
scratched. If a careful inspection of the
shaft ends reveals any imperfections,
you may carefully true up the points
