There have been cases of wings failing on aircraft due to cut threads. Specific cases were Tiger Moth and Stampe biplanes. See: and https://assets.publishing.service.gov.uk/media/5422f6c240f0b613420005a3/Stampe_SV4C_G__G-ATKC__02-88.pdf This second report also highlights how making the tie rod of consant diameter raather than the original waisted design increased loding on the threaded ends as the thicker, stiffer part did not share the load as well. I hve a old thread rolling die on my bench. It makes a nice bench block Robert Edited By Robert Atkinson 2 on 01/03/2023 11:58:24 Edited By Robert Atkinson 2 on 01/03/2023 12:05:38 |
