Scratched T-12, 1:16; metal
Posted by lposter on Monday, August 31, 2020 5:04 AM

Hello

The T-12 was an ill-fated prototype created in 1929 as a medium breakthrough tank by the Soviets that was quickly replaced by the T-24 after some testing. 

As far as I can see there are some conflicting informations as to what it looked like exactly. It seems there are some drawings available that show what it was intended to look like, some photos of how it ended up in prototype form and some photos/drawings of T-24s that are mislabelled as T-12s.

t12

 The above picture seems to show how it was intended to be. The two pictures below show models and graphiocs from the time of a T-12 that bears strong semblance to the plans above.

 Then you have what seems to have been built:

420471_2_i_022

 The Hobbyboss kit of the T-12 seems to reflect the photo above rather than what appear to be the designers intention

Picture 1

 The important deviations are the cupola, the cover on the drive sprocket, the engine deck, the front glacis/driver vision port and the rear end.

I will maker another post to avoid this one being to big........

Then there are some obviously mislabelled pictures such as the one below:

unnamed

 which is obviously a T-24 (the rounded turret back, cupola, track height and hull overhang on the tracks among other things giving it away. 

Then you have photos like this one which seems to show the designers version of teh T-12 (the back end of the hull does not resemble the T-12 as represented by the HobbyBoss kit but rather that of the designer version) and even this gets mislabelled as a T-24 which it obviously is not.

Picture 4

 Either way and irrespective of which is which and what actually was built in 1929 (there are references that confirm that the prototype was different from what the designers intended), I decided I would cobble together a metal 1:16 scale version of what I assume to be the designers intended tank.

The tank will be made from steel and brass and aluminium if necessary. It will be entirely scratchbuilt except for the tracks as life is too short. I will use Pz III tracks - I have a set in plastic and if it looks nice I will get metal ones. I will also use a PZ III sprocket as it is close to the real size in dimesion. I hope to make it RC ready to teh extent that it will have gearboxes and working suspension but if it never actually runs, I do not mind.

All the pieces were cut from 1.2 mm sheet steel using a jigsaw and then filed into shape.

 I will deal with the turret first. This was simply built up from the relevant pieces using a stiff solder. The brass thingy in the bottom is the thing that the drive shaft for the turret motor to fit into.

picture11a

 The pieces were added one by one until I got most of the final shape. The cupola is an aluminium petrol cap that I hacked up until it was OK. The cannon and machine guns are simply bits of stock brass formed into approximately what I needed (I'm not getting into a discussion as to what sort of machine guns actually ended up on the prototype!)

picture16a

 Here it is sans cupola machine gun which I will fit later. This cupola should rotate I guess otherwise I dont know how the hatch was supposed to open. 

There are some mistakes....some of the rivets are wrongly positioned but drilling those holes and banging in those rivets nearly broke me so I don't care.

Then it was onto the hull.

Here are most of the hull pieces held together with magnets. There are some problems ahead in that its not clear to me from the plans I have as to certain aspects of the hull. But most of these are not visible so Im just going to wing it. I hope to be assembling this completely in a day or two but first I have some butchery to do on a set of gearboxes to get them to fit in a space they were not designed for.

picture6a

picture7a

There were some mistakes made -surface blemishes, layout lines visible but Im hoping they will (A) be unnoticeable or (B) removable.

I will update this as I get more progress. The next thing will be the wheels I guess. Of which there are a delightful 32.

Amazing work! The turret is very nicely done.  Never thought I’d see someone build a T-12 in 1/16.
