I have been turning finials and take-down hardware on my lathes for 20+ years. I find it indispensable for turning dagger quillons. 

I would have a very difficult time doing what I do without one.

And the tooling and accessory list never stops growing.

looks like it came out pretty good. I started making mine from O1 or W1 and hardening them then tempering back to low 50s, helps keep them from getting messed up by the wrench. I have also found you can get a cleaner look by insetting the Major dia into the pommel, use a endmill or counterbore to pocket the hole , this lets the nut sit down in a little and helps keep things centered and even, this also allows the pommel to be curved and sill fit the nut. 
couple bits of advice.  if you have power feeds use them  the finish will be better. Get a drill chuck for the tail stock, collets will severely limit what drills can be used. when using center drills only go in half way up the second angle, they tend to break if you go to deep.  When tapping on a lathe , use a live or dead center in the tail stock on the back of the tap, that supports the tap and keeps it centered. Using a center leads to a straighter hole and less broken taps. you can also put the tap in the tailstock advance it pu tthe spindle in neutral and turn it by hand (or with a wrench) just run the tailstock in with the tap.  Run the spindle faster for the parting tool and make sure it is on center or just below. in general The smaller the dia, the higher the rpm, this is to maintain the same FPM of cut. 

A couple safety notes, It looked like there wasn't a handle on that file, NEVER do that on a lathe good way to put the tang through your wrist. also at he end of the video you left the chuck key in the lathe.. NEVER  leave a chuck key in,that is a good way to break yourself or the lathe. ALWAYS remove the chuck key unless actively using it.

Matthew Parkinson THANK YOU! honestly this is a very deep dark hole of learning.  Im loving having this machine and this was my first attempt at turning anything.  

All advice is more than welcome and very much appreciated!

lol so true! I think the machine was the cheap part.  

Wendell Bryenton,

How many warnings is a man allowed before his wife leaves him when it comes to buying more tools?

Michael Samdahl depends if you are telling her the real price 😉

(Im lucky because her hobby is pottery and we can compete on tool costs.)

Knife making is a life time of buying tools.

Then you die. 

I use tap handles that have an extension that fits in the tailstock chuck. This keeps them centered to avoid breakage.

Or like Matt said, if you look at the handle end of your wrench you may find an indentation. This is for holding center to keep the tap straight - which is going to save you many taps. 

Here's an example:  https://www.amazon.com/AD-INTERNATIONAL-Precision-Spinnable-Accurate/dp/B0CJTZ5P6Z/ref=sr_1_3_sspa?crid=1U57HPNXE4JKI&dib=eyJ2IjoiMSJ9.aMCG1xSlD2Iv3odbAD-kJ2rUdjsMHw9Qm4hnQRe1FkocQ7pDkpdL8qvZM4ZyIhDZhl5lqyJOLgmLYkQkhVB6MQz23CHrm9tTCcGuG45VHsQa2nhGn9cr9qEy2svTBwR2bNsDt3VlBxfidtxv-TdJhvHJw0zjB90en4I4x04b7OUzMVdImkiX5wcqi2Nmx6QO2tHko4UMOTFcm94A2yW0GfSYy5zjGu0PdRREhBq5p_-6lQH4nHPoCtmYNAR54Ces8oPqsBQ5b5dz-z1kJqVxX7AviJBBse5pIKZ4bu8KHWM.bGX3hfKl0X7JY5Ps0nuWmU9DoHfkoYbLsAPV0Sfd8vw&dib_tag=se&keywords=tap%2Bwrench&qid=1734009888&s=hi&sprefix=tap%2Bw%2Ctools%2C112&sr=1-3-spons&sp_csd=d2lkZ2V0TmFtZT1zcF9hdGY&th=1
