View Full Version : 1:16 Mahindra CJ4 (scratch built copy of my 1:1)

After building a couple of Willys Jeeps (1944 MB and a 1953 CJ3B) I had the idea to recreate an exact copy of my Jeep. I believe not many are familiar with this model since it is a Mahindra built in small numbers, so I'll first introduce the original. This is a Mahindra CJ 4 (note that Jeep only built one-of prototype CJ 4 model) built in 1970 in Bombay. It was imported to Yugoslavia (at the time) along with CJ3B in exchange with some weaponry. All the parts are identical to the Willys CJ 3B right down to the F-134 Hurricane engine. My father bought it in 1997 with only 12.000kms on the odometer and we've had it since. During the 15 years of ownership we've kept it pretty much original with the exception of the engine. It now has a 2.3 Diesel from a Ford Sierra because the Hurricane was very thirsty.

Here's the Jeep

I started the model this past summer of 2011 from the frame. Material is 0.4mm aluminum from offset printing technology and so far CA glue works great.

Started the body from the floors up. I used simple plywood dies and the result was good but with lots of space for improving

Here you can see the firewall in its rough form.
http://www.scalemotorcars.com/forum/images/imported/2012/03/239.jpg

Next I built the rear wheel wells. I don't have tools for stamping so I added strips of aluminum to replicate the floor patterns.
http://www.scalemotorcars.com/forum/images/imported/2012/03/240.jpg

The long rectangular part is actually the difference between the 3B and the 4. The difference is roughly a 30cm longer wheelbase for the CJ 4.

Mahindra actually started work by assembling Willys Jeeps after which they started building them completely in India under license.

Thanks HFC, I've been carefully reading your posts, you're doing great work

Next were some really difficult parts as I don't have the proper tooling, the hat channels which support the floor.
http://www.scalemotorcars.com/forum/images/imported/2012/03/244.jpg

I continued with the tool box which is located under the passenger seat. I didn't make the lid open because it is under the seat and most of the time you wouldn't even know it's there.

The work on the rest of the body started with the rear fenders along with the fuel filler neck

And another tough part, this time the cowl.
It was interesting to feel how adding some critical parts really stiffen the body.

then came the front fenders. This is the last "flat fender" Jeep.

the hood and the piano hinge which was a first for me. I think it came out good

That looks great. Nice detail and the aluminum work is outstanding. Are you going to do the engine out of metal as well? Ken

JeepMkd
03-19-12, 04:07 PM
I thought about building it out of styrene, but I changed my mind after having learned a bit more about aluminum.
The dilemma is whether to build the original Hurricane engine, or the diesel that's currently in the Jeep. I can't make my mind and that's one of the last "big" parts before final detailing can begin.

GARYDAVIS
03-23-12, 05:15 PM
This is a Great Looking build. Your craftsmanship is outstanding. A very cool subject too. It sure is handy having a 1/1 to look at during the build...isn't it? Good luck with the decision on the motor.

Exams finally passed so it's time for a little break from college. In the next 2 weeks I'll have some spare time so I would try to do as much as possible on my Mahindra build; the steel CJ2A will wait for now.

My father left for work so I moved all my tools from my freezing cold workshop into my room, he might not be very happy when he'll see the mess gringrin

http://www.scalemotorcars.com/forum/images/imported/2013/01/234.jpg

I'm starting the engine and transmission so I can finish the frame and drivetrain. I hope to throw some paint on this model soon.


The hard decision concerning the engine was made - I'll build the original Hurricane engine.

Hi Mite-

I have never seen a complete build from aluminum...this is fun to watch! Your level of detail is inspirational!

02-01-13, 05:50 PM
Thanks Douglas! When it comes from you guys, it really means something to me, I admire your builds every single day!

I started the engine, this one is a first for me so If you notice anything wrong please point it out

It looks like it's small, but that's only the engine block which is small by itself. When I add the rest of the parts it will be just fine

I still haven't gotten small enough nuts and bolts, and I want to finish it as soon as possible so a little soldering wire will do the trick this time
http://www.scalemotorcars.com/forum/images/imported/2013/02/13.jpg

I also did the cylinder head and valve cover.

The parts are held in place with one drop of CA glue so when fabrication is done I will dismantle everything, paint separately, and put together later on

The engine bay looks better now

Interesting project. If I'm correctly understanding, all is assembled with glue, no welding?

Yes, with my aluminum and styrene builds I use CA glue. It works great, it's fast and very durable. I have model ships and planes (also from scratch) built 10 years ago and they are ok.

Today I started the radiator core using Roger Zimmerman's technique and it works great!
But building it on a model half the size of the Continental that Roger is building doesn't allow to make it look great. It's fiddly, it's difficult and I won't be doing it on any model smaller than 1:10. And that's a promise!

Not bad for a first time! Don't forget that the distance on my own radiator between two tubes is 1 mm. If I'm looking right, you must have 1.2 to 1.3 mm space between the tubes. If you had use a little bit more paper to have a tighter zigzag, the effect would be better. Don't forget also that I had more than one day to do my radiator!

JeepMkd
02-12-13, 01:00 PM
Thanks for the help Roger!

To be honest, I came home this afternoon and jumped onto the core immediatly and was doing the job from what I memorised reading your thread.
Now, after checking your thread again, I think I'll add a little bit more paper tomorrow, probably double. It's not glued in place so it shifts freely in the space between the fins.

It's just the thing that I hate doing the same thing twice, but I'm determined to make this one look as good as possible.

Thanks for looking and greetings from Macedonia :)

Roger Zimmermann
02-12-13, 01:13 PM
Nobody likes to do the same parts twice! You are right, with adding twice the length of paper, you will get it right. With tighter zigzag, you may even not need to add glue. It will stay in place just with some paint. Good luck!

I'm running out of time, will be leaving back for college on Monday, so I want to get done as much as possible by then. Therefore, I left the radiator as it is, just added bottom and top parts and pipes.

I also did the air filter and the bits that go on it

http://www.scalemotorcars.com/forum/images/imported/2013/02/147.jpg


Here's the radiator, later I had to move the pipes to make room for the hoses.

http://www.scalemotorcars.com/forum/images/imported/2013/02/148.jpg


I did the water hoses with the spring and heat shrink trick, it didn't work out as expected .

I avoided them for long time, but I had to do them today, the cables.
http://www.scalemotorcars.com/forum/images/imported/2013/02/150.jpg



First trt was nice, but they looked more like diesel lines than cables, so I had to modify them. Too bad the red wire I used is too thick for the application.
