Threading Properly - I STUFFED up

Great video Aron, and thanks for mentioning me 😊 I'm glad it helped you, and you did make some great threads in the end 😊👍 Also, don't be ashamed of failing. It's what we humans do, - and this in particular, I've seen professionals with years of experience do as well 😊 Best regards from Denmark. Rasmus

Thanks Aaron for being so honest and setting an example to other YouTubers who leave incorrect material uploaded.

Hi Aaron, a person that never made a mistake, never made anything! Well done on the correction mate, good reference for others. Cheers, Jon

‘Honest Az’ …. Your new moniker. 🤣 Refreshing and educational. Thanks for all that you do Aaron. Regards Robert

Mate, ya just went higher up on me list. Any bloke that is willing to own his mistakes is a better man for it. Thanks for the video 👍🇦🇺

Aaron, I am retired fitter and machinist, I served apprenticeship in a heavy machine shop, we never angled the compound, even at tech/TAFE we just plunge straight in. That's with hss toolbit. I finish working at hyd. Repair company and all threads on the new rods were plunged straight in and rods were made out of 4140 steel, using carbide thread insert.

Gday Aaron, we’re only human and at least you had the balls to show your mistake, by showing this someone will learn by watching, great video mate, Cheers

Love your honesty and openness mate.

Enjoyed the machining Aaron and the alterations. Top result, thanks for sharing. Tony

Sharing your mistake will benefit many others. Well done.

In all the years I have cut threads on a lathe, including my apprenticeship, I have never adjusted the top slide to half the thread angle, I have always set the top slide at zero. The depth of cut is put on via the cross slide, and the top slide is moved into the thread direction by about a third of depth of cut, the last two or three cuts are full depth and will clean up both flanks of the thread. Guaranteed correct depth of cut every time, with no messing about with cosine error.

Hypnotic to see threading in slow motion. It looks great! I made this same mistake on my lathe because of how the graduations were marked out and what the forums and fb machinists were saying had me chasing my tail for so long. In the end I set the compound parallel to the thread angle and things just clicked. Nowadays, like you, I love the full form inserts, and also a solid tool post :D

G'day Aaron, I've certainly cut a Buttress thread turning the compound from the wrong axis. I now plunge cut from the cross slide and at the same time side cut using the Top Slide. Gives me control on finishing out the flanks. I guess we all have our own techniques and preferences that suit us. Cam

Aaron, many times when threading ,on the final size I will make light cuts only moving in the cross slide and get very nice results. The final passes Illuminates whatever the angle is on your compound. But you got it done and customers now happy. Guess that’s really all that matters. Gary

Thank you Aaron I am kind of a threading nut because it is the one thing I can do both pretty good. Thanks again for sharing .

If it's any consolation, you're not the first person to make that compound angle mistake on YouTube! Good job making this follow up video.

Awesome job Aaron!

Well done mate everyone will make mistakes fixing the problem is the talent 👏 👍

Hello Aaron. I just found your channel. I see you are a subscriber to Cutting Edge Engineering,also. I wanted to point you in the direction of Joe Pie.He made his first video,5-6 years ago because,he was frustrated with the videos people were making on the subject of threading.He showed his method of cutting threads with the tool upside down,spindle in reverse,threading away from the headstock. I tried this method and, I have to say, I have been using it ever since. I am happy to subscribe to your channel and,hope to pick up some tips.

Great video as always Aaron....I learnt something :)
