I planed to mod a T-72 to a PT-91 For the coming MGB, any one interest in this Group Build?

The reason why....
1. We share our modding methots and resources so that we can all build the tank with at least the similar type of conversion
2. We post all our progress here so that anyone interested can just join the GB and follow the correct path of conversion
3. There's more motivation and support when we build together



any takers??

since i just received my MHM T-72 from MH this shall be done for the MGB08...

so Vince u wanna lead the way of the build? since i have no idea what need to be change from the original T-72... from my view it not much.. the main thing is the ERA tiles..


and right about now the pictures adrian posted last year would become very handy indeed.. also i'm looking at Youtube for some more source of reference..especially from this guy karayaimanis :)

kuman

don't think the era tiles is a big problem, I'll kick start once I finish My Growler tonite, as I promissed to my self, no new kit without finishing an old one.

Actually I am planning to built 1 but don't kow where to start and what kit should I need to use to start it, since I see this threat, I MUST JOIN!!!!!!! plase add me in.

Do you think T-80 is better to build to PT-90?

Lee, you'll have to build it from a T-72 as that is what the Pendekar is based on. A T-80, although similar in shape has a very different engine deck layout.

From my observation, other than the ERA tiles, other areas that need work are:

1) Fenders - the T-72 and PT-91 front fenders are all metal. The PT-91M ones are rubber. The rear fenders are also cut short and come with rubber mudguards.
2) Tracks - PT-91M uses rubber-padded tracks. Maybe 'curi' from a Leopard kit?
3) Turret basket - T-72s don't have a turret basket.
4) Grenade launchers - lots of them
5) Obra-3 Laser Warning sensors - There are 4 of them. 2 located on each side of the main gun and 1 each behind the grenade launcher clusters.
6) Engine deck - I don't have a good photo of the engine deck but it appears to be different from a standard T-72 deck. On the port side on either side of the exhaust, are 2 boxes with vents that are not found on the T-72. On the starboard side, there's a small vent towards the rear.
7) Sagem Optics - the optics on the turret top have to be shaved off and replaced by the boxy SAVAN-15 FCS. There's also a rod-like instrument just behind it. In front of the commander's hatch, there's the VIGY 15 sight and a mount for the M2 browning.
8) Road wheels - PT-91M uses the older 8 bolt design. Some kits may come with the newer 6 bolt ones.

All in all, quite a fair bit of work. BTW, I bought a braille scale T-72, in the off-chance that I might join this group build. Still thinking it through....

1) Fenders - the T-72 and PT-91 front fenders are all metal. The PT-91M ones are rubber. The rear fenders are also cut short and come with rubber mudguards.
2) Tracks - PT-91M uses rubber-padded tracks. Maybe 'curi' from a Leopard kit?
3) Turret basket - T-72s don't have a turret basket.
4) Grenade launchers - lots of them, 11 on each side
5) Obra-3 Laser Warning sensors - There are 4 of them. 2 located on each side of the main gun and 1 each behind the grenade launcher clusters.
6) Engine deck - I don't have a good photo of the engine deck but it appears to be different from a standard T-72 deck. On the port side on either side of the exhaust, are 2 boxes with vents that are not found on the T-72. On the starboard side, there's a small vent towards the rear.

8) Road wheels - PT-91M uses the older 8 bolt design. Some kits may come with the newer 6 bolt ones.
9) The gear for the rubber track is diffrent, the ones that the kit provided can't suit the track.

I'm now doing the technical drawing, still in progress, will try to finish today, here's some update.



Here's some summary for the conversion,

1) A russian T-72 kit is required. the Tamiya ones comes with the older 8 bolt wheels while the dragon kit came with both types, I have no comments on the revell kit yer.

2) A track with rubber pads are required, just like the ones using in M1 and Leapord 2. In this conversion, I'll be using the track from my Trumpeter M1A1HA, the kit came with the nylon tracks and the plastic ones.

3) the gear in the wheels needs to be changed. either finding a new ones or scratch build.



4) Decals, I can do all the artwork but I need some help on the reference and printing.

5) the rest of the comversion can be easily scratch build.

i believe the grenade launcher we can make it use the cutton-bud plastics much like the method shown by Imran (or is it his brother) last time... its pretty much applicable.. :D

as for the rubber Gear track... i know that the track is different... but what the difference about the gear it self.. Vince can show the difference? edit: ok now i can see the difference!.. :D thanks vince

anyway how to modify the track... anyone? or maybe a donation kit is needed to use the track...

I got my MHM kits too, I'm in!

BTW, don't forget that the whole commander's hatch is also different. The T-72's turtle-shell type opens forward. The PT-91M has a more conventional flat hatch that opens to the rear.

10. Wind sensor on the turret rear

i checked my stash last nite it seems that i dont have the exact kit as you have Vince the one with 2 kinds of track in a box.. :( :(

so i wonder will this track work? abit expensive for just the track.. M1A Track



Leopard Track
HERE!!


dunno which is better suited for our "Pendekar " tank
:unsure: :unsure:

kuman

I got both of them in my stash, let me check and confirm. ;)

Jush had a teleconversation with Vince, he suggest to use the semi-individual track use in Trumpy M1A1. That kist come with one rubber track and two sprue of semi-individual track. :D

Btw, I got another one spare indi track too, left over from my previous Dragon's M1. Any member who really need it, pleae do not hesistate to drop me a forum PM.

I have spare 8 bolts wheels to spare.

From what I read the Pendekar tracks are Diehl so, basically it's the same with Leo II's.

Fuselage

1) Front Mudguards - Just scratch build with plaplate


2) Front Fenders - The PT-91M ones are rubber. and it's higher, Part of the side skirt needs to be trimmed off so that it's inline with the fenders


3) Rear fenders - cut short and come with rubber mudguards.


4) Engine deck - On the port side on either side of the exhaust, are 2 boxes with vents that are not found on the T-72. On the starboard side, there's a small vent towards the rear.




5) Tracks - PT-91M uses rubber-padded tracks, similar to those in M1 and Leopard tanks


6) Road wheels - PT-91M uses the older 8 bolt design. Some kits may come with the newer 6 bolt ones.


7) The gear for the rubber track is diffrent, the ones that the kit provided can't suit the track.


8) Anti-skid - The anti skid marks are actually stick-on, not like the ones in merkava and challenger

Turret
1) Turret basket - This one needs to be scratch build



2) Grenade launchers - 12 on each side


3) Obra-3 Laser Warning sensors - There are 4 of them. 2 located on each side of the main gun and 1 each behind the grenade launcher clusters.


4) Sagem Optics - the optics on the turret top have to be shaved off and replaced by the boxy SAVAN-15 FCS. There's also a rod-like instrument just behind it. In front of the commander's hatch, there's the VIGY 15 sight and a mount for the M2 browning.

5) Wind sensor on the turret rear

I think we have enought information to kick start, any more takers???

We also need some one who can build a base dio for these tanks, Personally I prefer the scene in the testing ground rather then the parade, the muddy tank looks better.

Many thanks to Alpha7 for the precious information and pictures.

Here are some pics of the Polish version built-up using the Trumpeter T-72 with Modelkrak conversion set:

Antonio Pang

Remi Tran-Van

AEF Design also makes a conversion set for the Polish PT91.

AEF designs Catalogue

BV, no problem. Glad they came in useful, although I regret not having the guts to climb up the trailer to take closer shots. Thanks for the photo of the turret basket. I didn't realise it was that big!

The Modelkrak conversion set is for an early version of the PT-91. The tiles on the turret are arranged in a curved shape whereas the PT-91M has a more angular look. It does save you from having to make all those launchers.

Hope to see more research materials....

I've taken BV's blueprint and added what I think the tiles on the turret and chassis are arranged. I have not added some loose tiles situated around the driver's hatch as well as the ones in front of the turret.

what is the side profiles?

The side profile shows how the tiles at the front of the tank are arranged.

You'll probably see it better in this photo. Notice that the top most row of tiles (which are on either side of the driver's periscope) are arranged horizontally while the rest are sloped. I guess the slope on my diagram isn't steep enough :D. Notice also the loose tiles scattered around the driver's hatch.

now i remember..two years ago, in tempur magzine...they have a complete pic for ths tank...

can scan and post the page my friend?

thanks Alpha7 for the info,

I Started the build by filling the switches hole, this is a motorized kit. This kit has more details then what I expected, not bad for a RM35 kit.

BTW, I remember seeing some good photos of the Pendekar in April issue of Tempur (or was it Perajurit). Regret not buying a copy cause I can't seem to find it on the newstands anymore. Anyone has a copy to share?

adrian..
i believe its Tempur.. since i have the April issue of Perajurit.. no Pendekar there..

i think Tempur distribution in northern region is worst.. since for the whole month of April i can only see the March (or is it February) issue of Tempur magazine.. pretty lame..

@BV...
- me too i already started mine .. now thinking if i should open another WIP for it.. and cross-linked it to this thread...

kuman

Guys,
this will look great in Merdeka08. Keep it up

should we put all our WIP here or open a new link?

moderators, please advice.

the kit provided track and the track frm trumpeter's M1, believe or not, ejector pinmarks on all inner pads....


The motor tool were used again, it's a handy tool, and all of them been "sapu-ed" on the recent TU sales.


test fitting, at least 4 spockets needs to be cut.


All the gears are cut off using nail clipper.


I attached it back using x'tra thin cement but look what happen....need help.

I've photoshoped the wheels based on the picture taken, it comes out 12 gears by calculation, but the problem now is 12 don't fit the track.

Most of the modern tanks have only 11 gears.
M1 - 11
Challenger - 11
Leopard - 11
Osorio - 13

Another issue is the M1 track has a bolt in the outer side of the inner pads, while the PT91 don't have those, the most suitable track I found for this conversion is the British challenger2 track.

Anyone has any used Challenger 2 tracks or some extra??

Vince,

I think you can correct them by sand off the sprocket tooth. Referring to the real photo above, the tooth looks thinner while the kit one looks wide.

Since we are using the M1 track for our PT91, there are a few step before I gonna scatch my drive sprocket.

1. the DIAMETER of M1 where you curi the track from.

2. the shape of the tooth.

In your case, I think is because of the diameter of the wheel... Try to trim up the teeth...

I've thinking of trimming the teeth but after dry fitting, It dosent work, leave me only one choice, abigger diameter or one gigi patah....

Vince..

if the "gigi patah" is the only option.. make sure the patah one will be hidden under the skirting... :D

or make a severe weathering and hide those under the dirt.. since we're suggesting to make a dio based on the "tanah merah" setting kan? a perfect way to hide track in-accuracy

i'm also looking at your step inorder to tackle the same problem later.. :D
good luck and keep the suggetion coming...

kuman

Kuman,

The dragon's M1 track will be sent to you tommorow by either DHL or Fedex. That will be a semi individual track, but I really cant find the instructin sheet, hope you can figure out yourself how to build it. :P

Yeah, I think Kuman got the point too... hide under the skirt. :D :lol: :D

ok, I think I will use the 11 gigi version or the gigi patah version. but will an M1 track with a bolt at the inner pads looks weired? the PT 91 track don't have it. the Challenger II track looks the most similar to the one used in PT91.
