Little track shoes falling off... time to research into a 3D printed track shoe.

Found a few bit of rubber dirt at the suspension area. Turn out that the vibration of the wheels seems to be rubbing on the head of the screw that is securing the suspension arms.
Even the use of 4 spacers sometimes does not clear the screw head.

Time to replace them with button arm screws to have more clearance.

That screw is a M3x20 but unfortunately, I can't find the half threaded version. Replaced with a general full threaded screws to monitor the performance.
I reckon some day, I will probably replace the suspension arms with a 3D printed version.

Working on new modification to the chieftain suspension.

Basically, I dislike the plastic suspension arm with the plastic shaft that holds the bearings for the centurion wheels.
I made a 3d printed replacement with a metal shaft instead. Design is still being refined at the moment.
Curious if anyone else might be interested in this design or maybe you could give some comments.
This is the initial version mounted on.

At the same time, replace the arm holding screw with a flat head screw. With the change of screw, I can take out one 1mm spacer and bring the wheel closer to the hull. This allows for slightly better track alignments.

Do comment if it works for you. Many thanks.

It's good of you to make the STL files available for free. Although I don't run my tanks very much, I am always learning about potential problems, so I am watching about your work on solving the problem with the screws contacting the idler wheels. Thank you for posting this information.

Thank you for the encouragement.
Will post more as I progress along.
