Advice appreciated!
I looked at your channel and find it a bit hard to follow without putting in some extra time. I think most "outsiders" or new viewers are going to find it hard to "enter" your channel quickly without some modifications.
You don't use your name so I can't even say this is "Jim's channel" in my mind. Some of your titles are descriptive but many are not. Many titles are probably not going to be meaningful to anyone except those the regularly follow you.
However, the one theme that I picked up that seems consistent is that you are handy, hands-on, and "fix-it" stuff whether it is car stuff, rebuild, repair, woodwork, toolwork, etc. So, you are into different "projects" but you seem to be a handy / hands-on person.
For example, if your name was Jim, the channel could be "Jim's Projects" (bland name because I don't know much about you or personality) which would help clue people in that you are into different "projects". Your playlists would be used to classify different projects into woodwork, cars, tools, etc.
If you have the occasional stray video, then so be it. I think most channels have the occasional stray video.
"What the Devil" is a saying, not anything you really own. Your channel name is a bit ambiguous which contributes to the confusion. Are people supposed to say "this is the devil's channel"? It is hard for people to latch on to.
I actually don't think your content is as scattered as much as you say because I see a theme. But your channel looks inconsistent in terms of titles and thumbnails.
