I make a handheld drill chuck holder for lathe tailstock

I have a few drill chucks that I can use in the tailstock of my lathe.
None of them are suitable to be used with really small drill bits or very small taps.
So I decided to make a drill chuck that I can hold with my hand and sense what is happening in the workpiece.

In this video I use:
- Weiler Matador SV (1972) Lathe
Chapters:
00:00 Opening animation
01:01 Introduction
05:42 Parting off the workpiece from long material
10:01 Measuring the collet chuck accuracy
11:51 Drilling a hole through the workpiece with parabolic drill bit
15:11 Drilling and reaming the hole to exact 12 millimeters
18:37 Turning the ends of the workpiece to be concentric with the hole
23:33 Setting the top slide angle to Morse 3 using Jim's Lathe Compound "Sine Bar"
28:44 Turning Morse 3 taper using top slide
34:34 Setting the top slide angle to B10 using Jim's Lathe Compound "Sine Bar"
42:05 Turning the B10 taper with top slide
47:01 Attaching the drill chuck to the sliding bar
47:39 Trying out the drill chuck
50:34 Conclusion and Bye
50:59 End credits
The video is spoken in German but it has good quality hand written subtitles in English, German and Finnish.

Nice tool to have. I have a very small lathe with a #1 taper in the tailstock and wanted a tiny slip chuck but they are all 1/2 in. straight shanks for use in a drill chuck or collet.I can make a slip chuck like yours with a tiny Albrech chuck. Thanks for the ideas. The compound slide sine bar is nice but I'll just have to fuss my way through some other way. I always enjoy your videos

I wonder what the music was while making the mkt conus.

[@FinnoUgricMachining]

That artwork was composed by Tomaso Albinoni. The name is "Adagio in G minor".
Wikipedia: en.wikipedia.org/wiki/Adagio_in_G_minor
This music is mostly heard during funeral activities. It has a slow tempo and a melancholic atmosphere.
Edit: One thing about this composition is that it was composed for church organ and strings. Most of the performances out there omit either the strings or the organ because these require a very different acoustic environment. Strings do not like a long echo whereas the organ requires it. This is probably the reason for the slow tempo noted in the sheet music.
However, in a DAW (Digital Audio Workstation) it is child's play to have these two element having a very different acoustic environment. Maybe it does not sound realistic but it sounds good 😀
