    Your method of machining is based on what is expedient and required, no more. You have spent a great deal of time over the years eliminating the BS to arrive at what works and is timely. Your comment about liking to work with a zero instead of a number backs up my theory. You, like me and almost anyone else, can remember a zero. It's not an arbitrary positive or negative number spawned in the depths of the universe that is almost impossible to recall with consistent accuracy. Zero is simple and direct much like your methods of using the tool or machine. Kudos to you Sir.

    Thank you for clarifying something that always seemed completely stupid to me and that is the preoccupation with the compound that too many people seem to have. Cutting threads from left to right in reverse is simply the bomb too. Love your common sense approach!!!

    Hi Joe I'm just the old retired guy that plays in the shop when it's not too hot or too cold. In other words, not a machinist. I was a little lost at first about running the cross slid in and running the compound in and setting to zero. When my brain made the connection that we were setting the depth with the cross slid and running the compound in to that depth and setting it to zero, I said WOW, I just learned something new from Joe. Thanks Buddy

    Hi joe im really enjoying your videos. Specially since I'm not a machinist or engineer. My grandfather was an engineer in Gibraltar back in the day when ships was built. I admired him alot. He was given a large medal from the Gibraltar government for his long term years he spent with the company. During the war up until the middle of the 70s. he started from the very bottom and worked all the way up to being one of the bosses. He treated all his Co workers with respect & he was liked by all. And when he came to retirement it was the guys that put in for his great service of gratitude of thanks that the government gave him a gold medal. The ships he helped built was astonishing as well as the planes he put back into service after the second world war.. I' miss him so much. I wish he was still around to share his experience with me on working with a lathe.. But I'm certainly learning alot from you joe. I can't wait to get my new engineering lathe up and running. Your videos and your long term experience is worth a great deal and is so valuable to people like me that' has a great deal to learn. . Thanks so much for these videos and the time you put into them and share. I hope some day I get to be proficient. On my lathe. A thousand thanks joe. Your the best buddy. Hope you get well soon my friend.

    Joe I just subscribed a day or two ago. I love your professional setup approaches that you show in your videos and the way you video them also. I have been a machinist for 50 years and can appreciate what you show. Proper setup is one of the most important things in machining. Cutting chips does not make you great machinist. Setup, technique and efficiency does. You have good knowledge and teaching skills. Nice to see that being shared with the rest of the world. Every time I see someone threading into the work I feel the stress just watching. I don't know why anyone would put that stress on themselves plus take the chance of ruining a piece. I sometimes put an indicator against the toolpost to get my depth of cut. That takes a different setup for thread length if critical. I also use the method you just described without an indicator except I use my crossslide (that has a thread stop) to retract my tool. I still use the compound to feed in except for my finish cut. They both work no trig needed.

    Joe, as a licensed, registered, and certified moron I can honestly tell you that I instantly understood what you were trying to convey. I don't know a lick about machine shop stuff, but it seems like a pretty simple concept to grasp (without even finishing the video yet). Use a part as a back stop, turn 1 wheel back x amount say 3 turns, now goto another wheel set at some funny angle and see how many turns it takes to get to your backstop say 5 turns then make a mark or set a zero, now back way off, get all setup and start turning the second wheel till you get back to your zero. Seems to me that there might be a great lack of common sense out there or over complication of a great many things, but to me maybe just a simple foundational understanding of how ones tool(machine) works is all anyone ever really needs.

    Hi Joe - Enjoy all of your videos very much. You said, "Whatever works for you", so I'd like to share mine. Back in the day in a busy shop where we were cutting all kinds of random threads every day, I never messed around with compound slide angles at all - just left it 90 degrees to the cross-slide. Sharpened the tool to 55 degrees (our part of the world dealt with a lot of English stuff). Then just take each cut, 5 thou in, and 3 thou on the compound. Then to finish, 2 thou in and 1 on the compound. Quick and easy. Got to keep the boss happy, and just get 'er done.

    Hi joe, from what i am seeing and hearing my method of thread cutting is waaay different from the rest. I too believe in the threading tool "flat" being as small as possible, but my compound slide stays linear to the bed of the lathe. We use a formula (for metric) 1.3 x pitch to calculate final depth. When cutting the thread (also towards headstock) i use my compound slide taking 3 cuts per depth adjustment. One centre, one left and one right. The thread is then cut so that the crest and root are the same width. I am in this line of work just over 5 years. I was taught this method and it works for me. But great videos Joe it really helps a lot. P.S. this method is great with two and three start threads as you simply turn the amount of pitch on your compound slide to start the next threading cycle.

    Love your style Joe.... I'll be using this as an absolute equal second to what I've always done and that's been to use trig. with having figured out a quick way of setting the compound to very fine decimal degrees.... But even still, your method of setting the run length of the thread has got to be quicker and easier and far less fiddling around to achieve the same thing. I've not seen anything you may have done on Metric Threading which I do a lot. I've set up a sure fire system of disengaging the half nuts when necessary and checking the thread with perhaps a 'screw on' and then re engaging the entire gear train to restart further passes if the need be, with no loss of position. A much needed skill and happy to pass on any info to anyone who needs to do the same or like all of us, has accidentally disengaged those nuts and then cursed and started a new piece. I'm sure you'd have your own methods here which I'd certainly like to see.... Excellent video. Thanks.

    What a well-crafted and planned lesson and demo! Good job, Joe. If it was your intention to confuse and mislead us with ambiguity, technical double-speak, and unfathomable jargon, you failed miserably. Combined with your previous lessons on reverse threading and "angle" advancement with the compound slide, you've given me a useful education on the single-point threading process.

    Another brilliant video Joe. Just a few suggestions that some viewers may find handy to achieve the same goal without arithmetic etc. At 16:40, with the tool just touching the workpiece, set both dials to zero; back off the tool using the TOP slide, then using the CROSS slide advance the tool by the desired depth of thread. This depth is read directly from the cross slide dial with no arithmetic necessary; then reset the cross slide dial to zero. Cut the groove by advancing the tool with the TOP slide until its dial again reads zero. The tool is now in the position it will be in when the last cut has been completed, both slide dials will be reading zero, and the groove will be the same form as the thread and in the finished location. Withdraw the tool using the TOP slide and move saddle along to “start-cutting-thread” position but pause the tool when over a section of work where the thread is to be cut. Using the TOP slide, position the tool to just touch workpiece. This will eliminate several passes cutting air, or gouging the workpiece! With the saddle in the start-cut position the depth of the scratch cut is applied using the TOP slide, and from now on the top slide handle will be rotated in a clockwise direction only. Depth of cut is applied only by the TOP slide; the CROSS slide is used to disengage the tool at the end of each cut and the CROSS slide is moved back to zero on the dial when the saddle is positioned ready to take the next cut. When the last cut is completed, both the top slide and cross slide dials will again read zero. With this method it is not necessary to remember any top slide readings before adding on the depth of cut, and again using your method, only the depth of the thread cut needs to be read from a chart. No trigonometry, arithmetic or numbers need to be remembered other than zero on the two dials. I hope this may be of interest to some viewers.

    Hi Joe, during my apprienticeship as a toolmaker, i learnd to do the advance with the turned (somewhat 29.5 to 30 degrees) compound slide, the cross slide was set to an even number (0) easy to return to. As metric tools usually do not have a thread dial, we had to retract the tool at each pass, reverse the spindle while halfnut still engaged and then advance to the next pass. So dial out one or two full turns to retract, wind back, dial in to zero advance DoC with Top Slide and on with the next pass. Tedious, but the real benefit was due to the magic of trigonometry - the real advance of the top slide is only half of the dial, we were able to produce highly accurate threads (sine 30°: 0.5). Another benefit was that only the left face of the cutter is engaged (the left side only makes a small spring cut), less stress to cutter and machine... However, great viedo again and again (and again), I watched all of them over and over, and whenever I will have the possibility to come to Austin, I'll give you a visit!

    It seems to me there are two types of machinists, those who only do things the way they were shown, and those with a brain. You are of course in the second class! Keep 'em coming, it is a good teacher that encourages people to try to break away from ages of hide bound, thoughtless, follow-my-lead dogma.

    I shall relate a little story many years ago I was demonstrating threading at an exhibition and using the straight in method, several oldies commented that you can't do that, it's not the way I was taught. Then another piped up that he was taught to top slide feed but on his first job after his apprenticeship the foreman told him to stop wasting his time and go straight in, he never looked back.Moral of the story,never believe the first person who tells you something, at least not without further research.Oh and follow my leader is how you get myths, so THINK for yourself.

    Thanks Joe. I find the common double depths on my fishtail. An, I use a sharpe mark on the way next to the carriage as my pull-out.. looking at the box is no good with numbers flashing by, and watching the tool cannot always be done as it disappears in a cloud of smoke when using thread cutting oil. But that sharpe mark is easy for me to see and I am quite bold in running up to it. ( Toward chuck ) Cutting away is better. However, on pipe threads and drill joints... there is the taper attachment lash which throws a monkey wrench into the mix. I usually run the rpm up until it looks a bit scary, and run a couple air-cuts to warm up. Thanks for all the tips! Mark

    This method works great! I ground a .005 tip and then easily and accurately cut five 1/2-28 x 1/2 inch practice pieces. Since I always fumble with the wires, I cheated and checked those pieces using a high-quality nut made by a gunsmith. I'd really like to try your technique of cutting towards the tailstock, but my lathe has a threaded spindle. Thank you for sharing this, and many other tips and tricks.
