Hi Johan - welcome to HomemadeTools.net

Sounds like you have a lot of experience that will be useful around here! Regarding the US Navy training manuals, you can either upload them as attachments to a post, or you can put them in Dropbox and post the links, or, if it's easiest, you can just email them to me at jon@homemadetools.net, and I can post them and credit you for finding them.
