Thanks! It has been my way to learn everything the hard way. Cutting threads being no exception. My training in machining has been OJT for the most part. Preferably with no witnesses. It's amazing what you can get away with when you don't know what you're doing! Your videos have helped me through a lot of projects.
You’re a brilliant man. Men like you are solely responsible for industry in this country and all over the world. Men like you as in intelligent men who know all the tricks of their trade!!!
Watched this the other day, cut functional threads today as I made new big dials per your video. I forgot to use back gears - but I managed anyway. Thanks for your wonderful videos.
Great Video Mr. Pete. I own a Atlas 6x18 and have been wanting to learn Threading. Thanks for showing it in detail. I have only been learning Machining for a short Time and am at the point where I need to be able to do Threading. Your Videos have really been a lifesaver . Thanks again for the Videos 👍
You are a great teacher, sir. I'm buying a lathe similar to this over the weekend. Atlas/Craftsman 12x36 with the quick change box. One owner with all the original paperwork and tooling. A great find. This video reminds me of my turning teacher in Trade School years ago. I'm only 34 and I'm one of the last of the conventional Machinists I think. I know of no one in my age range who is in the trade doing Conventional work. Everything has gone to CNC, but there is still a need for real job shop Machinists who can do things themselves. Thanks again for this refresher.
That sounds like a great Machine that you found. With all of the original paperwork. While you will have fun with that. And yes the days of the manual machinist are long gone. Need a few of them yet like you and I
As always thanks for the education Mr. Pete!! Guys, I ordered the Atlas course mentioned in this video from Mr. Pete and it arrived today, (very fast shipping), I'm enjoying it already and look forward to many more hours with my favorite teacher. I recommend his courses wholeheartedly, do get them!!!
Thank you. A friend bought an SB 9 (A? - it has the tumblers - is identical to your SB) that is clean, but has not been used in quite a while. I got the a, b, c and way oils, and we spent an evening getting it lubed up and ran it up, went through various configurations - with, without back gears, checked all the tumbler positions, etc. We did some simple turning and then tried threading. Threading was done on a 1/2" rod turned to 7/16 and threaded to a 20 pitch. (Protruding about 2-1/2" from the 3-jaw, unsupported in the tail stock). We had trouble with the first 1/4" or so being "double threaded" and then it settled out. I'm very familiar with ensuring backlash is taken out of the cross slide, etc., so I'm confident that was not a contributor. Do you think flexing of the work piece was a factor in the threading results? The lathe has a standard lantern tool post and we used a threading-specific HSS tool that came with the lathe - it has a crescent-shaped cutter held with a horizontal bolt and with the 60deg shape along the perimeter intended to be rotated up as it is ground back with use.
nice vid mr pete. a threading tool is a forming tool feeding on a angle has no affect,cause when the carriage is being driven along the bed the tool will only cut on the side that its moving to ,therefore feeding in the compound at 29 or 30 just adds fun to the task at hand. try feeding just with the cross slide and the thread results are the same. when you plunge the tool in the work both sides cut if the carriage is at idle. food for thought and also look up toms techniques he explains this theorie.
It just reminds me my first time cutting threads, very slow was still too fast... lol Practice and experience make good... ;) Excellent basic thread cutting video.
You're absolutely right about the speed and finish, when ever possible I'll try to thread around 400 to 600 RPMs, sometimes it can only be done at 100 or even less...
I like your idea of marking. I've had a couple of times where I must not have backed out as far as I thought I did and turned in so the crosslide was in an extra .100 and didn't notice. Needless to say the threading tool didn't like taking a cut that deep. :-)Thanks for the video.
This was very helpful for me- thank you! One question- what is the significance of zeroing out the cross slide? Is that so that the compound is always approaching from the same reference allowing you to control the cutting depth from the compound?
As always superb lesson Mr Pete. Could you recommend a quick release tool holder for the atlas/craftsman. I still use the old lantern holder. Thank you
+Todd Anonymous Aloris or dorian are best, but not affordable. Checkout SHARS--I do not own one, but have many of their size A & B toolholders which are just great. I have several other import toolholders that came with used lathes & they all seem fine.
Be careful there mrpete!!! You almost got caught on camera, the handle on the gear change is a bit too shiny and smooth :). Seriously though, thanks for another great video.
I. Have a 12 x 36 combine. I used to be able to cut threads,but a gear must have broke . Now it doesn't work.. do you have a video on how to disassemble to get to the gears? Also wondering if I can get gears for it?
While making broom thread adaptors (6 TPI) for broom and rake handles (which used to be hardwood and actually lasted more than one season!), I've had to violate your "never take the work out of the chuck" rule because every one I've done fits a little differently, or has different diameters, and they need to be checked as you go. In order to return the work to the correct position, I return the cutter to the last depth position, engage the halfnut and let it travel to about the mid point of the previous cut, then stop the lathe with the halfnut still engaged(the most important step!) I then return the work to the chuck so the the cutter is correctly positioned in one of the previously cut threads. Once the chuck is tightened, everything should be realigned correctly. I usually do a spring cut to make sure it's set correctly before cutting further. Note that a standard threading tool won't work, you need to grind one with a flat nose, usually about 1/16"wide. There is, of course, no reason to do this for common threads, and I would never do it with fine threads, but it works great for course threads when you can't test fit the nut/female part for whatever reason.
Tubalcain I need some advice on how to fix my automatic y access feed plunger not working, removed appren and cleaned up everything and oil gears, still not engaged with plunger pulled, please advise
I'm getting ready to learn(with your video help) thread cutting on a Craftsman Commercial 12x36 101.28990 all was going well until I tried to pull the back gear pin out, it won't release the gear. The pin moves a little then comes up to a hard stop. I'm hoping you might have an idea as to what I need to do to fix this problem.
+mrpete222 Thank you for your reply. I tried all of the above no good. I had the spindle almost out when the pin finally turned loose. There must be a plunger/pin and spring something under the underneath the bull gear pin if so it was stuck pretty good. Still have to use pliers to pull out but pushes in easy. This lathe had sat in a basement unused for quite a few years. Everything was dried up and stuck together. A good cleaning and lots of oil and it runs nicely now. I have a 18" South Bend and a Craftsman 109 but the 12x36 is the one I will learn to cut threads on You have made that possible in that you have taken the mystery out of threading. Thank YouRalph (64 and still learning)
I don't have a thread dial indicator on my Leblond (can't find one anywhere), Can threading be done by stopping the lathe at the end of cut, backing out the cross- slide and reversing the lathe leaving the half nut engaged?
+Moholo 88 I am not that good on making gears, actually have never done it, I see many thread dials on various sites but never for a Leblond 13 regal - I don't know if any of them would work, would guess the gear would have to mesh with the thread pitch on the lead screw and it appears to be a square thread. I would think the gear diameter may also be critical for synchronizing each thread cut, this may be a project over my head. thanks for the interest though.
That is how I prefer to do it, it's supposed to result in less chatter - especially with a cutoff tool. But my lathe, an Emco Maier Compact 8, has a bolt-on spindle connection. A threaded spindle nose needs some type of lock if you are using a chuck or faceplate.
I have an opportunity to purchase an Atlas lathe that looks to be in like new condition. How hard is it to put a quick change gear box on an Atlas lathe.
You remind me of my high school machine shop teacher. Your videos are very instructional, it's like having a conversation with a friend. Lathes are hard to find here in east TN. My wife doesn't understand why I want a lathe since I have retired. My brother and I are both wanting one, since we both had machine training. We each had about 1500 hours of training. We would like to set up a small shop to service local farmers, and auto hobbyist.

Everything but the actual gear setting for making the thread. I know that all lathes are diferent , but it so happens I have one of those but don't have the thread chart. (Gear settings for a given thread)

Glad to hear it
Thanks Mr.Pete I just followed your video and made my first 1/2-13 threads.
👍👍
It is always nice to see a clear explanation of this process. A lot of friends have asked how to do this. I’ll keep this video handy for them.

Good morning, and thank you. About the "loose" nut, if your threading is good, and it is loose, check to see if you have a bad nut.
+ElCid452 Thanks--good point
I have a question mr.pete. Could you tell me what the diameter and pitch are of the screws for the banjo bracket for the quick change gearbox?
This was very helpful for me- thank you! One question- what is the significance of zeroing out the cross slide? Is that so that the compound is always approaching from the same reference allowing you to control the cutting depth from the compound?
+deemstyle Thanks for watching
+deemstyle Allows you to back out-then return to that position accurately. All depth feeding is done with compound
changing to those new link belts quiets them down considerably

Only lathe owners know what is so fascinating about making a bolt.
Yes
While making broom thread adaptors (6 TPI) for broom and rake handles (which used to be hardwood and actually lasted more than one season!), I've had to violate your "never take the work out of the chuck" rule because every one I've done fits a little differently, or has different diameters, and they need to be checked as you go.
In order to return the work to the correct position, I return the cutter to the last depth position, engage the halfnut and let it travel to about the mid point of the previous cut, then stop the lathe with the halfnut still engaged(the most important step!)

I usually do a spring cut to make sure it's set correctly before cutting further. Note that a standard threading tool won't work, you need to grind one with a flat nose, usually about 1/16"wide.
There is, of course, no reason to do this for common threads, and I would never do it with fine threads, but it works great for course threads when you can't test fit the nut/female part for whatever reason.
