The publication welcomes documented application cases and reviews of a defined technical question. Start with the scope and evidence you can share; an introduction or a product claim alone does not establish a verified result.
Propose an application case
Use the case submission worksheet to identify the component, material condition, bore requirements, process changes, inspection method and actual results. Record who owns the data and which photographs, drawings and names may be published. Where information cannot be disclosed, state the limit explicitly.
A before-and-after comparison needs the conditions of both runs and the acceptance evidence. Provide the original report or records available for editorial checking. Historical source analyses already in the archive remain labelled with their evidence limits; a new submission does not change their status.
Offer a technical review
Use the technical review proposal to name the page and review scope, the relevant experience, conflicts of interest and proposed attribution. A public reviewer credit is added only after identity, consent and the completed review have been checked. A review of one calculation does not imply approval of the entire publication.
Send your exported proposal
Export your completed worksheet and contact the editorial desk. The worksheet does not upload files or send a message. The desk will agree the material to examine, permission to quote it and attribution before publication. See the editorial policy for corrections and source handling.
