- supahfly_remix 5y agoRight. What if they leaked?
- thehappypm 5y agoYou are asking “what if an industrial piece of equipment does not perform to specification?” The answer is, mechanical failure. Which apparently (again in the article) did happen a few times which eventually contributed to steel wheels taking over.
- mberning 5y agoI am wondering if they weren’t covered in wax or some other water barrier. Or perhaps the protective disc was welded at the seams. Seems unlikely given the era and the extra expense involved. It also mentions that they were known to fail, so one could assume exposure to the elements played a part.
- JackFr 5y agoArticle says after forming the paper core, they were painted. Presumably this gave them some water proofing.
