1/5 scale K2 black panther tank
#51
Thread Starter
The characteristic of the sprocket gear produced in the last episode is that it can prevent precession with three bearing supports.
Therefore, I expect the tank to operate very smoothly even if the body weight increases. The reason why spline and spring were applied to use the manual neutral gear applied in the last episode is that the hydraulic pump is driven using engine power, the hydraulic motor is applied using fluid flow by the pump, and the tank is moved.
Therefore, if the tank needs to be moved, it must be started, but the manual neutral device allows the tank to be moved without starting.

Episode 10 : Vehicle welding, various parts welding, and manual clutch disciple
Today, I will introduce the video first and explain each work process next time.
Regards,
Young
Following the last time, the rear gearbox connection is the standard for the vehicle body process.
Set the angle of the connection and tap the connection
Unlike previous versions, most structural parts installed are made of steel
Install a wire tray and a hole for the headlights on the front of the tank.
This is the detail of the tray above
Weld the body. It's easy to weld because it's steel, but there's a disadvantage that the structure becomes heavy
Perform partial primary welding.
The camera for filming the video was on top of the welding machine, so it was shaking continuously due to vibration.
This is the rear of the tank where the first welding has been completed.
Inside the connection, waterproof silicone work will be done later.
This part will be welded later.
It shows various supports attached around the turret ring. It's different from the previous version.
It's the front of the body
Bottom of the front of the vehicle
In the case of the vehicle body, welding from the inside may cause contraction, so all welding is done outside
The k2 Black Panther tank is not symmetrical, so there are many differences in detail
The body has been turned over for lower welds.
Fill in the fixing spot welds thoroughly
It's welded to the whole thing
It's welded to the entire lower part of the entire lower body
Welded the rear towing part
Welded the front towing part
The body was hoisted by welded towing parts and ropes
The body has been moved to the workstation.
The finish weld is carried out.

This has been a very good thread and I've really enjoyed following along, but I can't help wondering, why did you pick such an oddball scale as 1/5? There's virtually nothing else available in this scale, no accessories, no figures, etc, Etc. Had you gone with 1/6th you would have a vast amount of accessories to choose from, everything from figures to weapons to little 1/6 scale wine bottles. I suppose you could just use the 1/6 scale accessories anyway, but to me that has never quite looked right. Not as bad as the guys who use 1/6 figures in a 1/4 scale tank, but it's still noticeable to my eye. So why 1/5?

Not as bad as the guys who use 1/6 figures in a 1/4 scale tank, but it's still noticeable to my eye. So why 1/5?
First of all, the conclusion is that economic feasibility is the most important point in model production.
I personally have armortek 1/6 scale chieftain and kingtiger.
That's why I know the benefits of a 1/6 scale with a 12-inch action figure.
There are many differences in price between model parts and industrial parts.
For example, a 1/6 scale four-cycle gasoline engine costs at least 900 usd, while an industrial four-cycle engine applied on a 1/5 scale costs around 200 usd.
This is because inexpensive industrial products can be easily applied when choosing 1/5 scale such as iron plates or bearings, which are the basis of materials. And in order to make it by hand, a slightly larger size is advantageous for making it.
However, if it was on a 1/4 scale, it was selected on a 1/5 scale because there was an inconvenience in moving.
I have both a 1/6 scale F16 and a 1/5 scale F16 from Skymester jets.
So I bought a 1/5 scale figure from a British manufacturer.
It's not like there's no 1/5 scale military action figure at all.
In addition, this tank is not manufactured in bulk or made in batch to produce a certain quantity like Armortek.
It is only a work that is made by hand for a certain period of time, so all the items and necessary accessories are produced by hand.
Nevertheless, it's cheaper than a 1/6 scale tank.
It's not enough, but I'm sure you'll understand since I answered.

Young

In the previous version, this part utilized a 3d printer output, but this time it's made of steel.
The front cover is manufactured separately and installed after cleaning the surface
Secure the front cover with bolts.
The characteristic of the k2 tank is that it is not symmetrical. Since the front camera is installed next to the left headlight, the cover is installed asymmetrically.

Episode 11: Engine room cover and fixture
This week's episode is about making an engine room cover and installing support to fix it and making a fixing hook.
Unlike the previous version, this part was made of steel, not aluminum, and the deformation of the shape was modified because of the heat generated during welding.

Installation of the round bar for body fixation, The entire threaded bolts below are temporarily installed
The round bar is secured to the body with a flat head bolt
Inclined plate fixing plate will be temporarily installed to rotate in round bar, positioned afterwards and welded to round bar
Unlike the previous version, it is made of steel, not aluminum, and can increase strength and prevent contact corrosion.
Engine room cover welding completed, mesh installed later
Temporarily place it on the vehicle body to check if it is made at right angles to the deformation of the vehicle body
There is a gap due to very slight thermal deformation, but overall it is good
Engine compartment cover body fixings
Use table vice to perform pin work
Finished pin work
Processing for handle installation
Welded attachment to engine compartment cover

A bolt was installed in one hole, and a ball plunger was installed in the other hole
The length of the ball plunger was cut and welded.
Due to the heat of welding, the spring of the ball plunger melted and the ball went inside. However, the function of securing the engine cover works well.
Fabricate the connection between the engine compartment cover and the round bar support
Welded the connections to the bottom of the front of the engine room cover
Stretched over fixed round bar when engine room cover closed
This is a body reinforcement for use in the next episode.
These are the parts that will support the bogey wheel's shock absorber for the next episode.
In this version, we are considering applying the same posture control function as the symbol of the k2 Black Panther.
It will continue in the next episode

Check the strength of the compressive force
The angles of No. 1 and No. 6 of the suspension device are slightly larger than the rest, and the spring is also strong.
The reason for holding the angle and force strongly is to maintain the shape when the caterpillar is installed.

Those look like "die springs". I used die springs for my 1/6th KV-2 build since they are so stiff. They usually color code them like that based on the strength of the spring. Nice work.
