Notification of method change: Caterpillar casting production
The tank manufacturer decided to manufacture and install the caterpillar of the 2023 1/5 scale Black Panther tank (project name: ic2504) by casting method. The optimal method is to increase production efficiency and reduce the number of iterations.
The shape of the track is somewhat different from the actual one, but it is strong and has increased assembly efficiency.
The production is outsourced processing, and the outsourced production has been requested today.

Young

This episode was continued in the last episode with bogie wheel work.
The thickness of the bogie wheel of the 2023 K2 Black Panther (ic2504) is 1 mm thicker than that of 2022, and the shaft cover also runs with the bogie wheel.

Ep07-1 : Making a Drive Wheel
From mid-April, K2's work speed seems to be accelerating.
This is because another project is currently underway first and it needs to be finished.
Today's episode
The material required for drive wheel fabrication is mod steel. Prepare two seamless pipes for laser cutting and drive wheel shafts.
The drive shaft is a hexagonal round bar. The inside of the drive wheel and the hexagonal round bar must be connected very precisely. Therefore, the work is carried out by checking the coupler elaborately.
Check the clearance of the hexagonal round bar and coupler.
Finely dig out the inner diameter of the pipe to which the coupler outer diameter is to be seated with a shelf machine.
After machining cylindrical pipes dug to fit the coupler diameter at the depth of the design
The cylindrical pipe inlet outer diameter is also machined to fit the inner diameter of the sprocket wheel
A disk for fixing the sprocket is installed in the pipe opposite to the coupler insertion part
Cylindrical pipe with both ends machined so that both disk and coupler can be inserted
Tap the sprocket connection plate
The disk also works as a tap
Sprocket connection disks also tap
Tap operation is limited to all drive wheel components without omission
Thread work is done on all drive wheel components without omission
The couplers connected to the hexagonal round bar are welded in three pairs.
Coupler welded with grooves in a straight line
The coupler is welded thickly
Align the coupler and cylinder vertically with each other for welding
Tap Prevents thermal deformation by inserting a piece of hexagonal round bar into the coupler before welding the coupler and the cylinderand align with a small cylindrical pipe
Prevents thermal deformation by inserting a piece of hexagonal ring rod into the coupler before welding the coupler and cylinder
Tig weld the coupling between the coupler and the seal leader
Again, use a small thread reader to heat-deform and hold the deflection
Welded with care for thermal deformation
It's a 360 degree welding
Carefully weld the coupler and cylinder firmly.
Later, the drive shaft to which the hexagonal round bar is coupled is joined in the above shape
will detail the drive wheel operation.
Next time, continuously

Young

Ep07-2 : Making a Drive Wheel
Following the last time, I will introduce the process of making the drive wheels.
The drive wheels are made of steel and will be polished toothed edges smoothly before installing the track.
Starting next week, the production process will be accelerated.
Regards.
Young
Once the cylindrical structure has been completed, welding will begin to secure the sawtooth gear wheels.
Fix with a temporary fixing wrench bolt.
Complex structures overlap. First, temporarily adjust the guide plate and seal reader insert plate.
Insert the above assembly into the cylinder.
Fine-tune the plane so that it is perpendicular to the cylinder.
Check Status
Welding preparation
Conduct fixed point welding
Remove the guide plate. Wrench bolts did not fall out due to thermal deformation when welding was performed without removal, as in the case of 2022 model
This place will be fixed with a hexagonal bolt later
It's a stressed area, so thorough welding is required
Finished welding fixed parts on top and bottom of cylinder
Welding of the outer fixing plate on the other side of the cylinder
Made in a lifelike shape for structural strength and three-dimensional effect of scale
Assemble the top and bottom sawtooth plates and shape them
Position the sawtooth with the 3D sculpture made in episode 1
Position the sawtooth with the 3D sculpture made in episode 1
Temporary fixation with point welds
Modify Location
full-scale welding
final inspection

Re-decomposing and waiting

Hmm...
If you compare the two drive sprockets, you'll notice the teeth on the model protruding WAY past the Links of the Tracks which I think might pose an issue for either the Track rolling on or off the Sprockets.
On a somewhat related note... Are they reusing parts of the Leopard 2 Family? That inner Hub of the Drive Sprocket looks kinda familiar 🤔🤨

Most Western-made tanks weigh over 60 TON and produce tracks using the German Leopard's trackmaking technology.
In the 1970s, when the U.S. developed a MBT in collaboration with Germany, it conceived a track called the T-158.
The tracks of recent NATO standard Western armoured equipment are similar.
Armoured tracks in Korea will be replaced with rubber tracks in the future.
South Korea has decided to independently localize its rubber orbit under the auspices of the Institute of Defense Development, as it has now used products made by Canada's Soucy Defense for its Redback infantry armoured vehicles.
Please refer to the link below for Korea's track production.
https://www.lstrackshoe.co.kr:8003/products/
In this model fabrication, the track will be somewhat simplified, considering the convenience and durability of fabrication rather than scale precision. (See previous news)

Young

The sample of the casting track by outsourcing arrived the other day.
The connection is more natural and powerful
Check by hanging it on the sprocket that was made last time
Tightly operated to show less track deviations
The material is bolt steel
It's harder than normal casting
Its surface is grayed out by working with Sendblaster
Make holes and tap screws manually.

It's a 2022 k2 and it's a miniature version of the real track.
Looking at the case where the smaller-scale leopard tank has one hinge point, the wave shape appears
As a result of reviewing the driving behavior with a 3D printer sample, the shape of the waves was severe, so the casting method was changed

Episode 08: Start building the body building
In this episode, body building begins. The body material is steel, and this work focuses on durability rather than detail, so it may have a slightly different shape from the actual vehicle.

Sink all holes without omission
Sink operation followed by a sanding operation on the surface
K2 Black Panther is different from left to right, so it makes a clear distinction
Move to workbench to verify configuration
Bolted the bottom of the body to reinforce the stress on the hole
A bolt is first welded by temporary welding
Bolt reinforcement is a work for durability rather than detail, which is different from real vehicles
Use a welding rod to weld reinforcement
Install the side of the vehicle separately
Construct geometry temporarily using a right angle magnet retainer
Construct geometry temporarily using a right angle magnet retainer
