Title: Chieftain MBT with Gas Turbine engine
Post by: Buzzbomb on July 20, 2023, 02:36:04 PM
So what if the original UK work on the Gas turbine engine on the Conquerer test platform led to a Chieftain development.
Using the venerable Tamiya Mk 5 Chieftain as a basis... as hacking up a much more expensive/better Takom version is it bit over the top.
Besides.. I don't have one of those in the stash at the moment  ;)

The standard engine deck top hull layout
(https://www.dropbox.com/scl/fi/kh1f0kljc9h38ehihb7vk/TurbChief_2.JPG?rlkey=bp4sgky63qisau4yx40i9ixu8&raw=1)

Pretty much it will only be a cosmetic change to the engine deck, so hack out some old bit and get a base for the new bit.

Working more on the revised Engine deck and pretty much got most of it done. A bit of detail work around hinges, handles, cover mesh and similar hoopla to will be next

Also got me thinking about what else to fit to give it a point of difference, using this base Mk 5 version ?
The Brits went down the road of the Composite armour path, but I wonder how it would look with some ERA blocks  rather than the Stillbrew fitout ?
Thought bubble only, as there is nothing fundamentally wrong with the stock Mk 5 in this sort of timeline.

Nice bit of scratch building  :smiley: Out of curiosity Is the engine orientation placed length ways or across the hull?

What time frame are you looking at for this build?  Thermal imagers might be another addition.

What ever orientation fits under the engine deck  ;) I really have not looked that deeply for this build it is pretty cosmetic.

Looking at maybe late 80's, so yes going down that path

Small update, some minor work on the engine deck and getting the stowage bins and turret together.
To try and give this version a point of difference, I have added IFCS (Improved Fire Control System) and perhaps an early version of the Laser Targeting that replaced the IR Searchlight in the later marks and improved NBC Filter gear on the rear of the turret.

Louvres on the rear plate, still a bit to go there.

The final tweak, if the Turbine makes the tank faster, then perhaps a track revision might make sense. to include rubber pads.
These are Leopard Tracks and I reckon I will go with them

The start of this train of thought was a pack of Resin Centurion Hush Puppy tracks I had in the tracks drawer.  The combination of not having a spare Centurion drive sprocket (the sprocket teeth layout is a lot narrower) and the fact that they were resin which required a bit of heat and bend business, killed of that plan, but some rubber Leopard tracks... why not.

I feel your pain. So many of mine stall out at the paint stage. And yet there are those strange beings who strip the paint off a model they built last week just so they can paint it again!

Yes, usually because they didn't procrastinate & think it through before they painted the first time. ;)

One of the many reasons i switched to acrylics was the relative ease of stripping the paint and redoing it - usually because I screwed up the paint job. Some of my builds have seen multiple paint-strip-repaint cycles.

So PSR can = Putty-Sand-Repeat and Paint-Strip-Repeat. ;D

All of a sudden, we are away
In primer

Then... ok.. Berlin it is. Let the Masking escapades begin
(https://www.dropbox.com/scl/fi/ydv8h8rzz8rpanbq13vbf/TurbChief_16.JPG?rlkey=jrce359ya4vscuwq2jv6b3153&raw=1)

All in all it did not take long at all, just a single session. Man I love SMS paints... dry to move the next step so quickly.
Masking, masking, masking. Couple of oopsies that got a quick re masking, masking.. then where it needs to be

So a bit of detail painting, decals and then a bit of a weather.
Tomorrow is another day  ;D

Thanks team, the painting was much easier than last time I tried it, I suppose the experience helped, but it is also the 3rd crack at Berlin Brigade scheme.

More than happy, I used the same article as a refresher on the Brit progress on the the whole turbine development program

Well that is about it.
What if perhaps a Gas Turbine version of the Chieftain was developed and went on to be part of BAOR during the late 80's through to the 90's ?

Other than an Antenna or two, that got overlooked,  I am calling it.

I must say though, that the earlier BB chieftain on the right, was done a fair while ago using less information than is available today in books,
Hopefully you folks have enjoyed the Turbine Whine ride  ;)

Looking like legitimate gas turbine Chieftain on the outside to me.  Interesting choice of subject.  Camo is appropriately distracting to the eye.  :smiley:
