Bluing it certainly wouldn't have hurt. Kurtis clearly had enough confidence in his process to skip that step (or he didn'thave any on hand). He's not a tool maker and he's not selling it so doesn't need to document its accuracy for QC purposes or anything like that. He validated the result by using it.If the taper is even slightly off it may not do the job at all. Rubbing a bit of bearing blue and putting in the spindle will tell you straight away. It's maybe 2 minutes of effort. Re-machining the taper where you are removing almost no material will also take a very short time, particularly as he had everything set up.
Couldn't agree more, but not testing if your taper's fit is any good or having a look at your tool holder's runout is hardly chasing the last micron. It's just really basic stuff. It's not elitist or anything like that. It's what any tool maker would do, and even if you're not a tool maker its the sort of basic common sense thing that any good machinist would do as second nature. How can you make anything without measuring the result???
He's also not making it as a 'shiny thing' for YT views. For what he'll be using it for, it'll most likely be fine. And if it's not, then he's got himself another vid for YT, hasn't he.
At any rate, they are only doing the YT thing as a side gig. I think that's why it works for a lot of viewers. There's no planned video production, it's just Karen getting Kurtis to explain what he's doing and then videoing him doing it.
