Hi fellas,

I'm now in the process of making the PT-91 Malaysian new mbt.



The base kit is revell T-72 EDZ. It would be along and major modification task. On top of that, Malaysian army decided to change the sprocket from the original 14 teeth to 12 teeth.
All other T-72 kit that me and other local guys had (Mini Hobby and Tamiya) including revell kit came with 14 teeth sprocket.

One of them tried modifying the teeth by cutting them all and replace with styrene as the new tooth. However this is not strong enough to hold the tracks. I guess probably indi-links would work.

Anyway, just wanna ask is there any 12 teeth sprocket that available or maybe someone have a similar sprocket that look almost the same and wish to donate or sell to a poor modeller like me

the closet photos i could get is this one:


any helps and input from you guys are greatly appreciated.

I guess I would say to either use the T-72 sprockets and tracks (easy way out) or else you will have to build new sprockets...probably the way your friend did it, except you will have to use indy-tracks. The tracks are not T-72 standard anyway since they had to change the sprocket so...

If the rubber band tracks apply to much pressure for the teeth, and individual metal track links are cost prohibitive, perhaps your friend can cast his 12 toothed sprocket in resin . It'll be just as strong as any other then.

Thanks guys for your input.
Yup the track that mostly suitable is either Abrams or Leopard A2 tracks.

So does this means that there is not 12 sprocket in the market?? huhuhuhhu
No problem to me coz the easiest way is to keep the sprocket. Unless contest judge knew this fact, then there would be no problem for me...

We already asked the guy to cast it in resin and so far he havent decided to cast or not and the 'master' is still not ready for casting...

appreciated your inputs once again...thanks

Not ready? For something like a sprocket he can use modeling clay as a mold and just press the part into it. He doesn't even need to buy resin for the actual piece - hot glue will work for simple one sided pieces. Like you say, most people won't ever notice, but it'll bother you, trust me.

What i mean is not ready is the master is not good enough. The last sprocket he did had broken teeth

So he's doing another one and he will re-stock RTV next. Dont worry pal.. he's a true model building and he build model for a living.... Just wis hhe had the time to do this small things
and i agree it bothers me than anyone else if i dont change the sprocket.

Armour Track Models had a set ATX-9 German Type 570P "Diehl" Tracks (for Leopard 2 A5/A6 MBT) which included both sprockets and idlers. But this kit is long time OOP.

Zaidi,

AFV Clubs Leopard A2 tracks is the good choice. Actually there is one guy who is building PT-91 EX. The details you can find here:
http://modelwork.pl/viewtopic.php?t=7439&highlight=pt91
and here is a standard polish PT-91 build:
http://modelwork.pl/viewtopic.php?t=9398&postdays=0&postorder=asc&start=0

It is in Polish but there are pictures that might be reference for you.
In fact I have a question for you:
I am planning to build in the future one PT-91 EX in Malesian cammo. I found the few photos on the net but I see that you posted here an excellent photo. It will be very nice if you can post more photos of that tank here. Especially those showing the top.

Cheers!
