The Tiger Tank is one of the most recognized tanks from WW-II, has lots
of room inside and relatively simple lines ... all good characteristics
for a prototype model.

October, 2001:
Tiger Tank #001 is ready-enough to go into battle for the first
time, with all systems operational, but not completely finalized. Many
of the systems will need additional work over the coming months and years,
but wars are not always fought on engineering schedules.

Despite the large-scale of the models (3 ft hull length), it isn't easy
getting everything to fit into the turret, including a complete paintball
gun, paintball magazine, 3.5oz CO2 tank, elevate gears and motor,
rotate gears and motor, R/C receiver, servos and batteries, as well
as batteries for the rotate and elevate motors.
|
|
|
|
|
Turret rotation is accomplished using a small, one-wheel
locomotive that rides around the flat bottom of an 8 inch diameter
circular bearing. This particular bearing came out of an old jewelry
store display case, but they are readily available from surplus catalogs.

Viewed from another angle, the drive cog from a small geared motor is
seen driving an idler gear, which in turn drives a rubber wheel that
was scavenged from an old printer or copier (Will keeps us supplied with
plenty of take-out parts.) The 6-12 volt geared motors were bought from
a surplus catalog about 10 years ago and laid around the shop waiting
for this nearly perfect application of them. (It's always nice when
junk turns into treasure.)

A homemade elevate mechanism consists of a small geared motor, a drive
gear, a capstan and a length of line connected to the base of the gun.
Gravity lowers the gun and the winch raises it.

Fitting a 40 round, reliable feed magazine into the turret is not a simple
task. Here, a coil made out of 14 gauge PVC coated copper wire (standard
A/C house wire) is used to connect the rigid magazine to the gun,
allowing the gun to be raised and lowered. This approach is not totally
reliable, so additional designs will be pursued.

It always helpful to be able to easily and quickly work on all systems
within the tank, including the critical drive systems. As shown here,
the Tiger was designed to take a look under the hood whenever needed.

Dual heavy-duty speed controls (each 30amps continuous) are used to
control the drive motors. The speed controls are very robust, relatively
inexpensive and can be controlled using a number of different methods,
including analog or digital controls.
