What sort of content would people want to see? Flailing in my mess i can't see being much interest, unless it'd be like those hoarder shows... HA!
Good question! I thought I'd get a lot of traffic from stuff like my "first start in 20 years" 1972 Bronco video, but that hasn't generated much interest. I'm getting more action/views on my tech stuff, like rebuilding the Dana 60. I suspect it will be the same with the ZF-5 trans and 1356 transfer case build.
In other words, you'd get plenty of views and subscribers for stuff like what you're doing with your daughter's car, installing a trans in the VW, etc. If you resurrected a Fairlane, you could do videos on each step - fuel system, brakes, getting engine running, trans, suspension, interior, etc. You'd also generate plenty of views/subscribers from your waste oil burner fiasco....errr.....project
My perspective -- I'm going to be turning wrenches anyway, I might as well film it. Yes, it does take more time, but it also keeps me on task -- instead of taking a frolic and detour for a few weekends wrenching on my vintage chainsaws, I stay on task with the F350 because I am trying to post 2 or 3 videos a month to keep the channel going, build up my subscribers, and keep folks interested.
Wild-assed guess - if you started filming what you're doing and posted 2x videos per month of tech stuff, you'd hit 1,000 subscribers within a year, and as long as you have 4,000 viewing hours (you should as long as your videos aren't 2 minutes long), you'd start getting paid. It wouldn't be much at first - maybe $150 per month, but with 10k subscribers, it would be maybe $2k per month, and 10k isn't an unreasonable goal.
I think I'll hit 1,000 subs after about 7 months of effort, but I did get a jump start with my quasi-viral (168k views and 380 subscribers) short video of 4 baby armadillos tearing up my backyard. If I didn't have that, I think it would take me 10 or so months.
