Amazing job on the wheels! They will be unbreakable! Fantastic work.

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.

There is a very well-explained video about K2 Black Panther Tangk.

That is so awesome. Can I have one?

P.E.D. Marine

This is a great build to follow along with! The K2 is probably my favorite modern MBT, I would love to have one in 1/16th.

There's a person who made a limited edition on 1/16 scale in Korea. The price is 1/2 of the 1/5 scale version, so it's very surprising.

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

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

That process is a joy to watch. Thank you for documenting it.

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 🤔🤨

PE YOUNG

Most of the armoured equipment tracks in Korea are produced by LS Industrial Systems, a Korean company.

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

Thank you for your interest.

A few days ago, a sample of a track made by outsourcing arrived and will be inspected

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.

PE YOUNG

The reason why the producer gave up the track he worked on for over a month and created a new type of cast track is shown in the picture below.


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

PE YOUNG

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.

Regards,
Young

Transfer the pre-prepared body material to a temporary pallet for sink work and sanding work.

Every hole has a sink

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

Hold the right angle and position

Check the front and rear body material

The gearbox must be manufactured first before the body can be welded

In this episode, a gear box for driving a sprocket will be manufactured, fixed to the left and right sides of the rear of the vehicle, and the gear for the turret in the middle of the vehicle body will be fixed
