Scott here. A new viewer to your site. I can't watch enough. Your series went with Joe P's clip, which has helped me create a couple of one-off items for my 13" SB lathe. I have only been making chips for less than three years and keep thinking of new projects to learn methods. Thanks.
My condolences to you and your wife on the loss of her sister. Take care of yourself! Y’all (and me) are not spring chickens anymore. Thank you so much for your videos. I ALWAYS learn something new
That is a fantastic video you have helped me out immensely. Thank you so much I have watched your channel now only about a month and I have learned a whole lot. Again, thank you.
A helpful tip for turning external threads either single pointing or with a die. Notice in your favorite reference that the external diameter of a thread is NOT the material nominal diameter. It is slightly smaller than the nominal diameter. This is necessary to prevent the crest of the thread from binding on the root of the internal thread. What can happen if the thread major diameter is the nominal diameter is that even if the thread pitch diameter is correct measured by thread wires a Go-NoGo gage won't fit. While a hardware store class 1 nut may go on the thread, the class 2 gage won't fit. Taking another pass on the work makes matters worse. Now if you clean the thread up with a file and clean up the thread crests the pitch diameter is undersized and you get a sloppy fit with a tapped hole. Cheers from NC/USA
Hi Lee , thanks for the video series and I have enjoyed them. I was quite surprised to see you change the change gears when doing the external threads to turn down the diameter for threading so you could use the power feed and then you changed the gears back again to 18 threads per inch. I figured you either needed the practice or just like changing the gears. I would never have done that as I would have had it turned down manually before you had the change gears done once let alone doing them twice. Maybe I'm missing something. Keep on keeping on as I do really enjoy your videos. Dale in Canada 🇨🇦
Hello, new subscriber here. Great content, thank you. My condolences for your loss and I hope you recover from Covid. You should consider putting an Electronic Lead Screw on you lathe. Changing from feeding to threading is a snap, easy switch between metric and imperial. I have one on my lathe and love it.
G'day Lee. Another excellent thread demo. Very easy to follow & both pieces fitted together really well. Also the charts worked out well. Looking forward to your next segment. 😀
Great series Lee and excellent explanation, I can relate to the COVID issue, I missed out getting it during the whole pandemic and attended a 50th Navy reunion and got COVID, took about a week to get a clear result.
Had the original 2 part Pfizer vaccination and 1 booster. Family members that became infected varied from no vaccinations to being up to date with all boosters. It actually took several weeks to get full strength back, but doing fine now. Thanks for stopping by!
This is a great series Lee. Thanks! One question...I'm new to threading and I'm wondering about the threading dial. When you say "wait for the number to come around", does that mean you wait for the same number you started the process with or does that mean any number...as long as you are right on the number?
Most small inch based lathes have an 8 thread per inch lead screw and a thread indicator marked 1-4 and a mark between the digits. If this applies to your lathe then: if the thread to be cut is divisible by 8, then engage the half-nut on any number or line. If the thread is divisible by 4, then engage the half-nut on any number. If the thread is not divisible by 4 or 8, then engage the halfnut on just one number (e.g. 13 threads per inch). If the thread is a fractional thread like 6 1/2 tpi or metric do not disengage the halfnut, but back out the cutting tool, stop the lathe and reverse the spindle rotation and back up the thread cutting tool to the start position. Being long winded I guess, but there is a trick for cutting threads where normally you can't disengage the half nut. When you get to the end of the thread, disengage the half nut. Shut off the lathe and let it coast to a stop. Notice that the thread indicator hasn't moved much from the number you were using. Back out the threading tool and start the lathe in reverse. When your number comes back to the mark, re-engage the the half nut and back up to your start position. Rinse and repeat.

There is a powerful piece of thread software

I'm pleased that you're on the mend from COVID, and hope that the rest of your loved ones recover as well.

This information is good for the home/farm type of work. It will not produce a thread that can pass inspection in a professional situation.
Prayers for you and the Family Lee. Feel better soon. Even with COVID amazing video series and information. God Bless You Lee.
This has been a great series. Thanks for the video keep on keeping on.
Wonderful informative video , Thanks Lee !
Thank you for sharing all the valuable information, Lee. It is much appreciated.

good videos and explanations. Keep up the good work.
Hi Lee,
Thanks for the spot on videos please keep them coming, but first get well. thanks Tony
great content, really enjoy this series. 👍
That is a great tip. It should serve me well. 😊
Great tip Lee.👍👍👍👍👍😊😊😊😊

Thanks for the video on this. 👍
Good to know information . Thanks
Nice.
after you single point threading, do you change your gears back to its original setting, or do you leave your settings with the threading settings.
Excellent! Big question tho…what’s your vaccine status? And the fam? One week to recover is very good. Keep it up and keep the videos coming

@@aceroadholder2185 WOW! Thank you for this excellent explanation. I'm going to print it out and keep it for reference. Very kind of you!
Great presentation Lee, now you can make me a 20 mm 13TPI bolt! Cheers!
Easy. 20mm outside diameter with a 13tpi thread
