I just started viewing this set of videos and I think we need to start compiling George’s words of wisdom.

Brilliant work as always, George. I don't think I have the patience to do what you do. It looks like there was a small seam at the end between the shank and stem. I suppose the only way to perfectly eliminate that would be to refinish the whole pipe. I always enjoy your videos and it's pretty informative the little tips and tricks you mention amidst your ramblings.

I gotta get me one of those VFD? set ups.
Thank you George, I again learned quite a bit and had a few assumptions torpedoed.
I am curious about why the shank profile was so carefully scribed onto the face of the rod stock. I initially thought that was going to be used to profile the saddle off the stummel, but I didn't see where it was used.
I will admit that I high speeded through some of the videos, but still haven’t seen anything more about that scribing.
Did I miss something?
Thanks again.

It was a safety net in case any hand tuning was needed following the hard buff step.

In this case, the etched line was completely erased, which is the ideal result.

Understood.

Another couple of questions.
I notice that you used a tapered 1/8” bit for the airway, with the 0.128” step for your aircraft drill bit.
My understanding from this forum was that 9/64” and 5/32” were preferable airway diameters.
Did you use 1/8” because that was the original diameter of the airway of this particular pipe or is there another rationale.
I also noticed that you didn't discuss or demonstrate your slot cutting method other than noting that this master used a “shorter, taller slot.” Is that covered in another of your videos?

The .125 & .128 holes are for construction purposes. The airway is made larger after the work is done (except bending, of course) if wanted/needed.

Here's how:

And here's how I do slots:
