For those that make things, especially fiddly bits for their projects, this forum https://www.therpf.com/forums/ may be useful for the many different techniques used in movie/tv prop replica making. It also happens to have people that work in the business posting about their dayjob work, like this one https://www.therpf.com/forums/threads/kpd-blaster-ls-gun-from-netflixs-live-action-version-of-death-note.281053/#post-4308725 ; having met a few people that do that over the years at scifi conventions, I find it interesting. I also like seeing the processes people use to come up with stuff, and then actually implement it. (which is part of why i read around here so much).
