Howdy, it looks like the forum software was recently replaced and I'm having trouble finding information unfortunately. For example in this thread, the old links are still to the old forum:
https://forum.shopsmith.com/d/5092-everything-mark-5-v-technical-info-documentation-links/5
So every link in that post that went to a forum post doesn't work. Typically, your forum software should provide a migration solution that'll go and RegEx all the links in your database for posts and update them to the new links based on what the old post routed to.
New owner trying to find information but immediately hit that wall. I'm sure I'll still be able to find information I need, but just figured I'd mention this issue as it's likely a problem for many other posts.
