M16 Half Track "Meat Chopper" Korea 1950 - Build

This section is for builds that are not strictly Tamiya or Heng Long. For instance, replacing the electronics from a WSN or Matorro, or even a scratch-build.

Hi,

When raising the armored windshield, the three supports bars need to be crafted. Closer inspection reveals that they are more complex than thought, not just a stick. The idea is to create something as close as possible with the material available.

Not everything can be 3D printed. These are actually providing support and do help keep the armored windshield solidly in place. Having brass tubes and strips of all kind of sizes is important for such build.

Details shown on the door in references.

The flaps needed to be thinned significantly to be realistic. 1.4mm Meng nuts and some brass tubes are required. The tie downs remains to be created and will be added at the end of the build. I found that these are usually fragile and I would lose a few during the heavy manipulation of the model during the build. Better keep fragile stuff for the end. The door handle which was only a blob of plastic has been removed and redone in brass. Still need some refining and improvement. It is not uncommon for me to redo things twice or more until I am satisfied with the results. I have to see the small items on close up pictures to really notice the quality and determine if ok or not.

As seen at the start of the build, the door interior have no details at all. For a open compartment like this, it needs improvements.

Interior view of the right door as seen in my reference book shown on the first post. It has a metal map case, locking mechanism and bolts. Those 3D graphics are fantastic and are mandatory for this detailing. Other views of the interior frame were great. Highly recommended.

I tried to do something similar but without dimensions, its all guess work and done on a best effort basis so that we can have something interesting to look at on the model.

The handle was hand crafted from 2mm brass rod using nail files.

Left door interior detail. Notice the frame around the doors as seen in references, easily reproduced. But the cabin plastic is a lot thicker than the real M16 so some compromises are required. I did not see myself thinning all that plastic. Ensure that the interior nuts are matching the bolt location seen on the exterior side of the door and walls.

Overview.

Capture9.JPG
1/16 RC M16 Half Track MGMC Meat Chopper Korea build


Before installing the cabin on the frame, I need to fix the 3mm gap issue shown on the first post. I determine the anchor point at the front need to be remove and redone. I am reinforcing the remaining bracket as the main anchor.

Capture10.JPG
1/16 RC M16 Half Track MGMC Meat Chopper Korea build


Recreating a new anchor for the front. The highlighted section will be glued to the bottom frame and the cabin will be removable using one screw easily accessible.

Capture11.JPG
1/16 RC M16 Half Track MGMC Meat Chopper Korea build


The new anchor point.

Capture11a.JPG
1/16 RC M16 Half Track MGMC Meat Chopper Korea build


The front is now resting correctly on the metal frame. I am noticing that a lot of details are missing here and will require attention.

Overview of the model with the re-installed cabin. Looking much better than before. Now let's try to put on the rear armor section.

Damn, there is still a 1mm gap between the two sections. So, the gap was reduced from 3mm to 1mm, still not good. Further investigation reveals nothing wrong with the assembly. All the anchor points are aligned with their holes on the frame. Redoing the anchor point 1mm away is not ideal. It is a design or original construction error when the holes were drilled on the frame.

I have resigned myself to add a 1mm plasticard strip as a spacer glued to the cabin to close the gap with the rear section. Both sections remain independent but are now back to back. Not ideal but it resolves the issue fast and simple.

It goes without saying, but I shall say it anyway. Your attention to detail is outstanding. It is almost as if BarryC has lent you his aliens

Biggest issue with this model is lack of power on front wheels.

The lack of drive to the front axles of most half tracks was a real problem when trying to turn the vehicle and often the method of steering became a combination of muscle through the steering wheel and slewing the vehicle on its rear tracks,
There are plenty of pictures of half tracks with the front end in the air with the tracks providing both drive and steering.

Real halftracks yes, but model often have sometimes trouble with running. It's probably possible to make front drive in the front using HL truck parts.

I looked at it but I felt it was too complicated as I did not have the equivalent required parts.

Capture25.JPG

The WSN model comes with a embedded suspension spring inside the wheel hub as shown with the red arrow below. It's weird but it does provide a level of suspension. Replacing the axle would also mean replacing the hard plastic spring lead suspension by something functional that looks as good in order to maintain the accuracy of the model, its highly visible.

Capture22.JPG

It could also mean replacing the gearbox or differential, and moving the steering servo somewhere else.

Capture23.JPG
1/16 RC M16 Half Track MGMC Meat Chopper Korea build


A WPL axle is too long and too big to fit, and the M16 wheels are custom. Probably the best option is to try to put gears inside the WSN axle, keeping everything in place, and running a drive shaft to a new differential.

Maybe a future retirement project for an M3...

Thank goodness for home 3D printers because you are more likely to find Unicorns grazing your front lawn than you are in finding a dealer with an abundance of WSN/Torro M16 front wheels for sale :lolno:

You have cool friends !

Continuing with the build.

There is a bracket at the front that is attaching the upper hull to the frame and need to be reproduced on both sides. It is glued only to the top section. There is a nasty screw hole in the frame in front of it that needs to be filled.

Capture2.JPG
1/16 RC M16 Half Track MGMC Meat Chopper Korea build


Capture1.JPG
1/16 RC M16 Half Track MGMC Meat Chopper Korea build


There are also two screw holes on the front bumber that must be hidden. Some bolts heads seen in the Gun Power book were added on top.

Capture2a.JPG
1/16 RC M16 Half Track MGMC Meat Chopper Korea build


This is the battery box. Missing bolt heads on the top, so I redid them all with Meng nuts for consistency.

Capture3.JPG
1/16 RC M16 Half Track MGMC Meat Chopper Korea build


This is a graph of the SCR-528 radio as it should be, made of transmitter and receiver.

Capture3a.JPG
1/16 RC M16 Half Track MGMC Meat Chopper Korea build


This is the simplified radio look alike part provided by WSN/Trumpeter. It has no resemblance to the radio used on the M16. This is really unfortunate. Even the static Trumpeter version has the same part. The M16 configuration provided by WSN is depicting an early version with 4 ammo boxes at the front and a reduced capability radio. Later versions (certainly the ones used in Korea), had a full radio and 2 ammo boxes only at the front.

A new radio set and front arrangement for the fighting compartment will need to be scratch built. It could have been avoided.

Capture3b.JPG
1/16 RC M16 Half Track MGMC Meat Chopper Korea build


The ammo boxes come in 3 versions, yes 3 different construction for exactly the same ammo box.

- First set of 4 at the front are the ones for storage at the back of the vehicle. Notice the nasty line going all around through the middle that will need to be filled.
- Second set of 4 are the ones provided for storage at the front of the vehicle. Notice the better quality, no nasty line to fill. The construction is different with much better design.
- Third set of 4 are the ones installed on the M45 mount and have an attachment for feeding the machine guns, and have the nasty lines.

It makes absolutely no sense for the WSN to have created 3 versions of those ammo boxes. Now, I will have to work a lot to fill the gaps, likely using a very thin plasticard.

The rear flap is resting on the storage box at the back, that's how it should be.

Capture7.JPG
1/16 RC M16 Half Track MGMC Meat Chopper Korea build


3 other screw holes need to be filled with plasticard and sanded smooth at the back. Notice that the hinges were somewhat recreated using a 0.8mm half round strip. It hides the joint between the 2 hinge sections since the original ones were all cut in half to separate the flaps. Notice the heavy sanding to remove unwanted stuff of all kind, including too much paint.

Detail of the locking mechanism, one at each extremity of the side flaps.

I did not put the small handling pins yet on the bars, it would be damaged and lost during construction.

Hinge detail. Some might want to use real micro hinges. Attempts in previous builds at using these were not satisfactory. They create weaknesses that required constant attention and fixing. I now prefer to have thing glued solidly in place, and not playing with hinges.

Capture10a.JPG
1/16 RC M16 Half Track MGMC Meat Chopper Korea build


I noticed the front cabin is missing a few levers. And the buttons on the dashboard would benefit from an upgrade in size. One thing that WSN did very well in my views are all the markings on this vehicle. It is really sad that they will all be overpainted.

Capture11.JPG
1/16 RC M16 Half Track MGMC Meat Chopper Korea build


I kept the dashboard removable so that I can salvage all the dials. I know Archer sells new ones, I will need to investigate if I should use them instead.

Capture12.JPG
1/16 RC M16 Half Track MGMC Meat Chopper Korea build


The seat structures are weak. On top of it, they must be pushed towards the front in order to have access to the screw under them, and remove the cabin from the frame. This is a bad design.

Hi,

This post is for the creation of the SCR-528 Radio.

Radios have a world of their own. On a open compartment vehicle like the M16, the radio is at the center stage of the vehicle so it is important for many like me to show the right equipment and be accurate. The M-16 was equipped with an SCR-528 radio, which was also installed in the M4 and M5 tanks, and most allied vehicles. It was made in various configurations, so if you look at pictures, there are many variations.

The SCR-528 for the M-16 is composed of the BC-604 transmitter on the left and the BC-603 receiver on the right. Some vehicles were equipped with two receivers on the right, replacing the box like section on the far right.

I was really disappointed when I noticed that Trumpeter/WSN did not even made a remote attempt to reproduce the radio, providing instead some cheaply designed fake box with one dial and some switches that is supposed to please 1/16 scale modellers.

After some research, no SCR-528 radio is available anywhere in 1/16 scale. If there is one in resin or 3D printed, its not advertised... Radios are usually a bit complicated with lots of small features, the market is probably limited. There are some German radios available but not this one.

This left me with no other option than to build one, at least one that attempts to look like it. Using pictures and various points of references, I extrapolated some approximate dimensions. The core components are cut.

Capture2.JPG
1/16 RC M16 Half Track MGMC Meat Chopper Korea build SCR-528


Assembled and put on their base. The cover box for the radio and its new stand will be covered in future post. This is just the radio.

Capture3.JPG
1/16 RC M16 Half Track MGMC Meat Chopper Korea build SCR-528


A few plastic Lego grills came handy to help me create the features.

Capture4.JPG
1/16 RC M16 Half Track MGMC Meat Chopper Korea build SCR-528


For the speaker cover, there is a limit as to how many micro drill bit holes you can drill in a tiny 8mm plasticard square, in a specific pattern... the required 37 is a lot. Its pushing my eyes to the limit and a nerve is being pulled in my back. Done on a best effort basis. After 4 attempts, I was getting somewhere. Maybe tomorrow with a cooler head, I will do another attempt with a smaller bit and get a better result. I have seen 2 patterns for the speaker cover but the other is even more complicated.

Capture5.JPG
1/16 RC M16 Half Track MGMC Meat Chopper Korea build SCR-528


This is the finished radio. I managed to drill 25 holes for the speaker cover in a more or less coordinated pattern. One thing about this hobby is that everything can be improved. Small Meng nuts are used to represent buttons and switches.

Next to the Trumpeter/WSN fake radio part provided with the model.

Capture8.JPG
1/16 RC M16 Half Track MGMC Meat Chopper Korea build SCR-528


My radio configuration will be the M16 version with complete radio and two ammo boxes at the front instead of 4.

Capture9.JPG
1/16 RC M16 Half Track MGMC Meat Chopper Korea build SCR-528


This is it, a SCR-528 done in 3 hours of work.

Capture10.JPG
1/16 RC M16 Half Track MGMC Meat Chopper Korea build SCR-528


Next step is to create the new stand, radio cover box, antenna and integrate these within the M16.

I wish I had known of your search for the correct radio fascia, I could at least have saved you a few wasted hours having already looked long and hard and found nothing of any use ,
I then searched for someone anyone who had made up a decal set of the Transceiver front.Nix, Nada, Nothing.
If it were a small item I could get away with a bodge but it takes up a lot of space in the cab and it cries out for detailing,
Well done you for achieving such a high standard and shame on WSN/Torro for neglecting the job.

Good Morning,
I was really hoping that a Trumpeter sprue set would have gone a long ways towards resolving this. Well, it is early days yet. Someone seeing your excellent reproduction work may be inspired to create a 3D model and print some out.
regards and following along!
