coming days I am too busy, but after that I will see if I can find something more about those tracks

Re: Soviet BT series tanks
I could only find these pictures, but maybe you can calculate hte other dimensions this way. By the way, this seems the BT-5 track.

Re: Soviet BT series tanks
Thanks Jaap! As you know I have Martin Rek's excellent 1/10 3DP BT-7 files but given the thin stamped plates used for this earlier track, it's difficult to make them look accurate. Colin worked up a modified track design that is better but still not exact given the limitations in a printed link.

I think if you want to print this, it will not be strong enough.Xiaoshan_Sailor wrote: ↑Wed Apr 17, 2024 7:21 am Thanks Jaap!

Re: Soviet BT series tanks
I have leant that BT1-2 and 3 were all manufactured to inch dimensions, the BT4 was just a BT3 , but produced to metric dimensions.
With this in mind , I reckon that the early smooth bottom links were probably 10" pitch. Which converts to 254mm.
So my guess is that the actual pitch was probably rounded up to 255 (or maybe left at 254).
The early longer pitch smooth links look very weak as they wrap.around the idler wheel. But they are the simplest to make.
If I go ahead with this project I will have them laser cut from steel. I will still have a lot of machining to do to finish them.(Model Engineers Laser in the UK, provide an excellent service).
