Sorry, but I would not be pleased to have the tracks as ugly tight as shown above. This may do it for a 1/16 plastic model but not for a model in 1/6 scale. My models are used also in rough grounds, and they nevertheless have a track tension like the real ones.

That is a fantastic looking jagdpanther, I suppose track tension is a matter of a bit of trial and error.
I hope my panther running gear looks as good as yours.

I know I had posted this resolve for the lack of adjustability on the King tiger idler-figured it would be the same on the JT too. As pictured I had a new arm machined with more swing to it. With removing a track link set you have approximately 2" which is too much and then the tracks are way to tight and can cause damage to the drive. The custom machined idler unit gives the ability to bridge that 2" gap and worked perfect on my KT.
Hi Dave. Thank you for the advice and photos. PM sent.

Hi Dave,
Good to see this custom machined idler unit can solve the track tension issue. Wish it is still available for JT builders.
Do you have the contact details of this machinist ?
With regards,
Lerh Chang

(Sorry David B. Highjack your thread again.)
I replace the LHS stock 90mm tension screw with a 100mm one. Cut the tension Arm material a bit to increase the moving range, and put them back like this :
- See both the tension screw plate and tension arm are cut to add the moving range. Also tap more threads on the longer tension screw.

I then add the LHS track back to 48 pairs of link , the track now looks like this :
- The track tension is still not enough.

I think I need similar Idler unit like Dave Macri's.

We did 47 pairs on ours and they did stretch.
It would be good if an admin started a new thread so as not to keep cluttering Davids thread.
