The “Is DIY right for you” post contains a lot of links back to the old forum, many are useful and should be brought over here and possibly updated, others we already have a thread for; just need to change the link.
To name one, I think we’re missing a post explaining what parts to buy in what order and how to check for compatibility. What obvious tools people MUST have, and so on. Something like this https://electricboardsolutions.com/blogs/building-an-esk8/diy-esk8, but more in depth.
