@798unionpipeliner I am a machinist and we employ over 15 people at our shop. Pretty much most things labeled "Made in U.S.A." When it comes to machines were american employed. There are plenty of jobs out there, just need the training and experience.
@astriknon well i live in houston tx there is some manufacturing here but thanks to rick perry most who have them jobs are mexican's that's why i asked what state are you in,,do you know of a union i can join to become a machinist
nice job. Hey what I find funny is that this guy films himself winding a chuck on a homemade thread with one hand and still holds the camera more steady that most of the amateurs on youtube trying to film alone.
somebody here said to try cutting from the shoulder out that it would give a good finish,, well it would also give left hand threads too... did anyone think to ask this guy doing the threading if he is new at this and if he is , he is doing a great job and if he is an old hand at this, he is still doing a great job because i am sure he is having fun at home with a lathe !!!!
Notice the deflection of the cutting tool from the shaft being threaded at 1.05 min. This is an excellent example showing deflection of a cutting tool from the work. Great video
Nice cutting. I am very new to the art form. How were you able to have the machine start at the exact space each time you started another run on the lathe?
@5687678 You see in the first pass that he reverses the spindle, so the feed is also reversed, thus keeping the same lineup every single time, never disengange the feed. If you wanna go back and make a deeper cut, back out of the workpiece, reverse the spindle and let the feed do all the work. Sorry if I don't make sense, english is not my primary language :)
@SPUNKKK This is how I cut threads at a job I had 20 years ago. Sometimes miss that time. I'm into computers now, work and repair on them... Fun project, making 20 bolts from scratch. Doubleended with different threads on each end, THAT was fun, hehe.
I'm getting so tired of all these CNC douche bags thinking they are sooo smart and know everything...when in reality they don't. A monkey could run a CNC. Classes take what? 2 weeks? Anyone could press a couple buttons and watch a machine do everything. Yes, CNC is obviously better for mass production. But seriously, leave the manual machining to us people that are actually capable of using our head.
@johnswburg nice to see some one mention this!!!! have you noticed how all the youngsters keep on about how much easier it is to just use the tool at 90 degrees?? shows how much they do know dosent it!
Just curious, but why do you stop the machine and reverse it to run the carriage back? Can't you just disengage the lead screw and wind it back manually? (I'm assuming you're using a chasing dial). Seems like it would be faster and a little easier on the motor.
@Barnekkid some guys just dont like the dial, he is making 1/2-20, if it is a metric lead screw with out a conversion gear set, there is an acceptable error that can only be maintained if the lead screw IS NOT disengaged
My old Boss taught me to set the compound slide to the same angle as the thread, then feed in with the compound slide, that way the cut is made on the leading edge of the tool bit so avoiding the tip breaking, so for a metric 60 degree thread set the slide to 30 degrees, having said that i done some screw cutting recently and fed in with the cross slide no probs, just took it easy just like this video, thumbs up :-)
Its good to do, and good to hear people still do it manually. I am use to cnc now, so this job prob be done in 30 seconds!! . It is hard to try and write it on here for you new guys just starting out. But hope this puts you in the right direction, and helps understand how to do it. If you do take a bit too deep depth of cut, it can be more likely youl chip the tool. Also if you doing manual screwcut, prob need to be 50 rpm max. Keep leadscrew engaged all the time, till done thread.
if you doing screw cutting on manual lathe. Then you need to check in zeus book the thread depth. Touch tool on to od. If you got a DRO then set to 0.0mm or actual dia of job.Eg M10 = dia 10mm Really what ever you prefer. (If no DRO then use dial on x axis handle) Then each pass prob 0.15mm, its your choice. (see how it cuts) so first pass on DRO 9.7mm (0.15 depth, so 0.3 total). next pass 9.4 etc. But may be deeper you go reduce depth of cut. Take backlash into account too.
It's not CNC, right? So how do you do this? I just started learning this job so I understand one pass - you set the revolutions, tool speed - ok. But how do you enter the thread after the first pass.
@les777pl there is, there is a spindle like thing that spins and you pre set it for the thread pitch, so when he engages the machine it will catch back on and cut the same thread every time. now if he was to move the piece at all or dial in/out on his compound then he wouldnt be able to anymore and would be force to reset it all. which can be a pain in the ars.
@BillyBob3430 Hey Dood.The only way ya can do it in one hit is to use a die. So on manual lathe you can put die in holder and if you bring tailstock up to job and put die on front of job, then wind tailstock out to locate on back of holder, You can have lathe on about 40 rpm,then as you turn it on,it will wind die onto job, you slowly turn handle on tailstock to keep die square on job.The more you do it the easier it will get. Then when you got die on to req place, turn lathe to reverse.
set the compound rest to 29 degrees on less and use the compound rest to increase the depth of the thread, you get nicer threads, and you are less likely to break off the tip of a tool.
not if you dont mind a left handed thread and a right hand thread on the same part.! in order to thread outward you have to put the tool on the other side and reverse the chuck rotatiion
why can you not just reverse the machine and penetrate deeper, instead of backing off going back and resetting the thread dial.....am i missing something???
@ninja6kid The answer is backlash. There is some built in clearance in machine tool ways and screws that will not allow what you're describing. The cutter tool would not be in the same exact place. It would also be turning the opposite direction, which would make the cutting edge dull, and even worse, it would cut. A faster way for the person making these threads would have been to use his thread dial chaser, assuming this lathe is so equipped. Hope that answered your question.
@ninja6kid because the piece would be cutting from the bottom of the tool, which obviously wouldn't work...he would have to keep changing the feed back in forth to reverse which would probably end up taking longer/more work. I don't get why he actually stops the machine though and then runs it in reverse like that. all he has to do is disengage it and dial it out while the machine is still running, then dial it back in.
@ThePLANxZ Some lathes require the half nut to remain engaged at all times when thread cutting certain threads. ie my lathe requires the half nut to remain engaged during metric thread cutting. It is a pain in the arse but such is life.
A- this is the worst HSS cutter ive ever seen hand sharpened for threads, B- These will look like fu** when hes done because no oil/ coolant (ill bet anyone it makes a world of difference, if you actully care about your work.) C- Hes not using the compound on the lathe just diving in with his cross feed. Whos teaching people nowa days ahhhhhhh
@daytonamon40 A - the thread appears completely functional for the job. B. The threads look fine although probably not textbook. C. While using the compound is a better idea, I've cut many threads straight in and they work fine. Maybe he's not a machinist by trade like many other people and just need to cut a thread? I know, silly idea.
The best way to machine something like that is to turn your tool upside down and run the machine in reverse, then you can run it much faster without worrying about it crashing into the job... better finish to!!
@MostFunnyUserName On a thread that size it doesnt take long, it doesnt matter about the Diameter when it comes to screw cutting its when the threads have to be long it takes ages (except for exeptionally large threads, and abnormal ones like multi start square threads). This job probably wouldnt have taken more than an hour from start to finish that includes setup. Your looking at 2 diameters and 1 thread.
it's usually considered good practice to set the topslide over to half the thread angle - so for metric would be 30 degrees - and advance the tool using the topslide. This means that the tool will only be cutting on the one face, the benefit being that you are not trying to feed swarf from both cutting faces onto the top of the tool. The swarf will only be from one side and so clear a lot easier.
no need to reverse motor leave it running disengage drive wind back to end and engage again.watch (single point thread cutting on a manual lathe).i hope i can be helpfull.
@dublin0850 I suspect this is a metric machine, and if your cutting an imperial thread on a metric machine you cant use the chase dial, and need to leave it enguaged. The same applies when cutting metric threads on an imperial machine. This most manual lathes. I will be posting a video about it later in the week.
@shempship Hi! the piece that cuts just does it when the piece that is cut rotates in one direction only, the part of the piece that cuts is only up, the part that is under does not cut. Sorry about my bad english, I'm brazilian.
when i am cutting threads i do a light pass then test it with a thread gauge to make sure its cutting the right amount of thread per inch.thats important when you are working on expensive materials or an expensive item.
@shempship When I did threads manually it was at school in shop. They had us grind all our threading/parting/cutting tools by hand, hard work to say the least. But practice is what's key. I spent one whole shop period (~4 hours) practicing threads. Get a tool, get a machined rod and go. If it gets too messy or you get it just right, part it off and start a new one. When you get it, it feels REALLY great. Just take your time and don't disengage!
@Jostrumable Ok everyone in school made what we call a "widget". Different pitch, different TPI. Exactly, don't get in a hurry to get a project done. Practice...become a master of your CRAFT.
@shempship Death. To put it simply. A more complex answer would be disastrous destruction of your thread and possibly threading tool. Other than that there's no real reason to back off.
@tapper45 It DID look really weird. Freaky stuff, and pretty sure it was for the hell of it, or maybe he wanted something a tiny bit more precise than from a die. Not that dies haven't saved me at work before, just find it can take a bit too much if you aren't careful. Then again ours may just be crap.
@silv425 You're the type of guy I'd set up a Capstan/Turret Lathe for and put you in a low-lit room on your own just big enough to fit the machine and your ego, give you bottom bracket spindles to machine by the thousands, a bucket to release your shite into and a separate entrance for you to come and go to work. In fact I think there is a script here for a film; a mix between "Friday Night, Saturday Morning" and "The Machinist"
Thx guy for posting. As I said I'm not a machinist. Currently programming. Our shop was getting excessive tool wear. My boss called the insert maker and after we listed to them all parameters and conditions, they recommended no coolant on large facing ops. Really we were unsure. But...it worked. I kinda guessed there were some thermal properties at work that I didn't fully understand. Thx for the explanation and I'll be sure to pass the info along.
@AAfilmproductions Yeah, Surplusdipstick watches the entire process then says the ending is best. I find the dimmest opininons when gathering ideas for something productive. It truly is asotunding the amount of self imposed dunbing down I see in the replys.
This would allow for not having to turn off the spindle to stop before running cutter into shoulder. Set cutter depth at the shoulder and engage the lead screw at the appropriate split nut index with spindle off , then turn on, to cut left to right.
alternate set up, turn the cutter upside down, adjust cutter height so cutting edge is back at center-line of part, start cutter at the shoulder, left in video, moving away from spindle to right, spindle needs to turn opposite direction from in this video as well as the lead screw , apron moves right ,away from spindle.
To me it doesn't look like he needed cutting oil, the chips weren't blue or anything so the metal was not over heating and the tool wasn't becoming discolored so he was fine and he might not have used it so you can actually see what it going on better,
Wow. Nothing like threads on metal!

@MostFunnyUserName To thread it, would take about 10 minutes roughly. the entire job about 30. start to finish with all of the setups.

all you people have no care for your workpiece and tools ? O_o
sharpen your HSS tool, break the edges on your workpiece, set the tool height correctly because the front side isn't turned entirely
and to that, your adjusting seems to be pretty bad...
if you want to show something, do it properly!

it's usually considered good practice to set the topslide over to half the thread angle - so for metric would be 30 degrees - and advance the tool using the topslide. This means that the tool will only be cutting on the one face, the benefit being that you are not trying to feed swarf from both cutting faces onto the top of the tool. The swarf will only be from one side and so clear a lot easier.

dublin0850 11 months ago
@dublin0850 I suspect this is a metric machine, and if your cutting an imperial thread on a metric machine you cant use the chase dial, and need to leave it enguaged. The same applies when cutting metric threads on an imperial machine. This most manual lathes. I will be posting a video about it later in the week.
Keep up the good work.

why keep stopping the lathe i can cut threads and keep the machine running its faster .your fired.

@shempship Hi! the piece that cuts just does it when the piece that is cut rotates in one direction only, the part of the piece that cuts is only up, the part that is under does not cut. Sorry about my bad english, I'm brazilian.

when i am cutting threads i do a light pass then test it with a thread gauge to make sure its cutting the right amount of thread per inch.thats important when you are working on expensive materials or an expensive item.

@shempship When I did threads manually it was at school in shop. They had us grind all our threading/parting/cutting tools by hand, hard work to say the least. But practice is what's key. I spent one whole shop period (~4 hours) practicing threads. Get a tool, get a machined rod and go. If it gets too messy or you get it just right, part it off and start a new one. When you get it, it feels REALLY great. Just take your time and don't disengage!

@shempship Death. To put it simply. A more complex answer would be disastrous destruction of your thread and possibly threading tool. Other than that there's no real reason to back off.
Jostrumable 11 months ago
did you do this just for the hell of it?
it's way easier to use a tap/die for 1/2x20 threads.
there's no setup, just clamp and twist.
it looked like your headstock was advancing into the tool not the tool moving towards the headstock.
with the cam mounted to the toolpost i figured the back ground would move.
that's a freaky optical illusion.
tapper45 11 months ago
@tapper45 It DID look really weird. Freaky stuff, and pretty sure it was for the hell of it, or maybe he wanted something a tiny bit more precise than from a die. Not that dies haven't saved me at work before, just find it can take a bit too much if you aren't careful. Then again ours may just be crap.

@silv425 You're the type of guy I'd set up a Capstan/Turret Lathe for and put you in a low-lit room on your own just big enough to fit the machine and your ego, give you bottom bracket spindles to machine by the thousands, a bucket to release your shite into and a separate entrance for you to come and go to work. In fact I think there is a script here for a film; a mix between "Friday Night, Saturday Morning" and "The Machinist"

Thx guy for posting. As I said I'm not a machinist. Currently programming. Our shop was getting excessive tool wear. My boss called the insert maker and after we listed to them all parameters and conditions, they recommended no coolant on large facing ops. Really we were unsure. But...it worked. I kinda guessed there were some thermal properties at work that I didn't fully understand. Thx for the explanation and I'll be sure to pass the info along.

Try upside down and backwards. Turn the tool upside down, run the spindle in reverse, and cut from the shoulder to air. Much safer. Much faster.

This would allow for not having to turn off the spindle to stop before running cutter into shoulder. Set cutter depth at the shoulder and engage the lead screw at the appropriate split nut index with spindle off , then turn on, to cut left to right.

alternate set up, turn the cutter upside down, adjust cutter height so cutting edge is back at center-line of part, start cutter at the shoulder, left in video, moving away from spindle to right, spindle needs to turn opposite direction from in this video as well as the lead screw , apron moves right ,away from spindle.

To me it doesn't look like he needed cutting oil, the chips weren't blue or anything so the metal was not over heating and the tool wasn't becoming discolored so he was fine and he might not have used it so you can actually see what it going on better,
