Rear axle assembly
Continuing to work on the Mail Wagon, being created by adapting the Doctor's Buggy by Model Trailways.
The laser etched brass pieces add fantastic detail, but they are tiny and challenging to work with. They fit well once you wrangle them into submission. I do worry about the longevity, even with using super glue. I think that's because of how delicate the parts seem.
Here is the rear axle assembly. It's not very level or straight, but that is a limitation of the cast metal spring. It's somewhat pliable, so it doesn't want to hold the proper shape. I think it will be barely noticeable once the parts are painted a uniform color and the wagon cabin is added.
