if you rotate the spindle the center of the circle drawn by the laser is your actual center. this technique is used for bore sighting gun barrels and is accurate.
Recently bought and read Southbend’s “How to run a lathe” These tips strike me as the practical things a guy with limited equipment will do to get by. Thanks.
I'm a multi skilled engineer. This is the problem with pure machinists, they're obsessed with making everything perfect. I don't know how many times I put loose tolerances on a drawing, only then for the machinist to spend ages making the most perfect, close to nominal part in the universe. Mate, the thing gets welded up and smashed into place anyway, no one cares or asked for this. You come to realize that a lot of machinists mess around alot to boost their egos.
I'm no machinist by any stretch of the word (I have a lathe and that's as near as I get lol) and even I was "ummm, wut?!" at that. Let's not even get started on number 5 🙄
Number two will get you close but finish by running an indicator along, Replace that tool holder with a quick change type you will never look back, best upgrade you can do.
Nice video and presentation. Page 1:56 chucked laser pointer for tail stock axial alignment. This is a good idea with an illustration, can hardly be a solution until we offered verification and proof. Concern? Not all laser body axis is aligned with the axis of its output beam. Verification? Slowly rotate the chuck and watch the laser point deviate around the nose cone in the tail stock, and draw your conclusion.
Trick 1, you are better off to bump the face of the tailstock ram against the face of the part to straighten. You can also put machinists parallels between the chuck face and the part and tap it in with a hammer. Using the grooves in the jaws will usually put you out by several thou. Trick 2, just don't do it that way. That method is honestly worse than setting by the scale on the compound, which is generally pretty bad. You could be off by 5 degrees doing it that way. I would be willing to bet that if the user turned on the lathe you would see that there is probably 100 thou runout on the center. Trick 3 works OK, but a 4 jaw chuck and a dial indicator will give you another 0 in the precision. Trick 4, great, if you are willing to accept 20 thou taper per foot. The laser isn't likely to be true to the spindle, and you are really only eyeballing the alignment. The correct method would be to take the chuck completely off, put a test bar between centers, turn a clean pass, and check both ends with a micrometer. Then use an indicator against the tailstock ram and adjust by 1/2 of the measured taper, and repeat until the taper measures to 0. You can also put a precision ground bar between the centers and put an indicator in the tool post, then run the carriage up and down and adjust until the indicator needle doesn't move. Trick 5 is reasonable, and usually good enough. You'll probably have a little bump in the center of a facing cut. Trick 6 works OK but leaves room for improvement. Again, 4 jaw chuck and a dial indicator gets you another decimal place. Trick 7, try that with steel. You'll just spin it in the tailstock chuck, or spin the tailstock chuck out of the tailstock. The thread is also going to be undersized anyway because of the squeeze of the 3 jaw. Learn to single point thread. It isn't that hard, and it is way more accurate. Trick 8 usually results in the drill bit spinning in the tailstock chuck. I generally don't subscribe to the idea that there is only 1 right way to do things, but some of these methods can best be described as great ways to run scrap. If you are going to spend the money and time to get a lathe and learn to use it, learn to use it right. A good lathe, dialed in properly with a skilled operator can hit a tolerance of just a few microns. Using these methods you will be hitting tolerances of a few millimeters.
On using lasers for this purpose you must first put up a piece of cardboard as far away from laser as possible, rotate chuck, you will likely see lots of runought, adjust windage and elevation to eliminate run out, then continue with this method If you wish. He had very useful tips but this one is not.

@АлександрКулагин-э1ф бывают мелкие детали которые обрабатывать нужно в притык к патрону. Несколько комплектов кулачков эту проблему решат. Если они есть конечно
Why? Which particular "trick" tickled your ass? It's sad you have such a strong character impediment that you are sufficiently motivated to put your negativity into print. Your negativity is the fundamental reason you are a failure. Change your attitude, seek some help and the sun will shine on you. Good luck.
This is very useful information and neat tricks. Among other things, it shows beginners and casual machinist what thinking out of the box will get you... good results! Thanks for the effort you put into making the video!
1, 2 and 4 are utter chod. 3, 5 and 6 are fairly standard practice. 7 buy a die box or tailstock die holder. 8 buy a bigger chuck, 16mm Vertex made chucks aren't huge money
I was thinking the same thing and dropped to the comments... thanks for your input the business about using a dead center to set the compound was flat out weird why is he even trying to Chuck a number #2 or 3 Morse taper dead center in a 3 jaw chuck?....I don't know maybe I'm missing something?
I will not agree to the laser pointer method because the laser module inside most of the time is off center and mis aligned..rather take out the module itself and mount...dont worry it has a brass casing....I have hacked many laser modules😅😅
True, But for a quick and dirty solution. CUT the guy some slack it’s a small diameter and a long threaded rod. I’m no machinist, but I’ve had a machinist show me this one. As a hobbyist I know it’s not the best approach, you could go to the store a buy it. But what did you learn.
Commenting in the virtual world requires a high level of understanding and culture, this video is not for you, you could have left in the first 30 seconds
GENIUS!!!
0:28 into this and I’m already pausing to hunt down different size retainer clips. Hahah !
You can't guarantee a laser pointer beam is parallell to the barrel
Rotate it and the centre is obvious
Indeed ! Actually, in most cases it isn´t and can be amazingly far off.
@@SW-qr8qe, в любом случае точность будет ±1 мм, в то время как нужна точность в районе ±10 мкм

@ that’s what I thought. Don’t know about gun bored though. Cheers

Nice camera work, great content, thanks so much for posting.
Neat ideas
If you're not a machinist it's a must-watch. If you are a machinist, don't waste your time.
😁

Very nice and straight to the point!
good tips 😁👍
Bravo, piccoli trucchi ma di elevata utilità
Very good Turner
These were great! I am just starting out with a small lathe. Saved the video and keep watching | remembering what you showed.
Great job, colleague👍👍👍
😂 laser pointer in the chuck. funny guy
amazing 😍👏
bravo king hadi
A true machinist knows how's to achieve "perfection", bear in mind that "perfection" is subject to standards.
Thanks 👍
On No2, you didn't even bother to clock it up, that could have been miles out, holding it by such a short parallel section.
I'm no machinist by any stretch of the word (I have a lathe and that's as near as I get lol) and even I was "ummm, wut?!" at that.
Let's not even get started on number 5 🙄
Number two will get you close but finish by running an indicator along,
Replace that tool holder with a quick change type you will never look back, best upgrade you can do.
You are assuming that the laser is aligned with its housing, you should spin it to check for wobble.
Nice video and presentation.

Hello
Bilgilendirici videolarınız için teşekkür ederim 🧿
nice, is it a vevor lathe?
Nice🔥👏
1. A competent machinist probably wouldn't watch.
2. I am new to machining and found your presentation informative
Don't do it! There's better ways of doing those things.
echt geil 😍

If you wish. He had very useful tips but this one is not.
In any case, the accuracy will be very low, more than ± 1 mm, while the required accuracy is about ± 10 microns. 100x error
Nice video!! Very useful information!
Tuyệt vời
Do i still must know them if im not a machinist...?
❤
👏👏👏

Сделай в начале кулачков небольшие проточки и будет вам счастье и у детали жёсткий упор от торцевого смещения.
Это не всегда полезно. Но часто вредно

Ofeishhhhhh
The laser beam was a solid idea...
Any competent machinist would be laughing his ass of at this.
True, piss poor tips that mostly won't work accurately. Should be taken down so beginners don't copy them.
This wasn't really intended for competent professional machinists, was it? Certainly not machinist trolls.
Why? Which particular "trick" tickled your ass? It's sad you have such a strong character impediment that you are sufficiently motivated to put your negativity into print. Your negativity is the fundamental reason you are a failure. Change your attitude, seek some help and the sun will shine on you. Good luck.
This is from the person who is doing his first time on lathe.
I doubt your imaginary ass laughing competent machinist is you. Well, the competent part anyway.
Question for every illustration...."is it within. 0001?"
The laser trick reveals a lack of understanding. Put the laser-pen back in and run the spindel, you'll might be surprised!
This is very useful information and neat tricks. Among other things, it shows beginners and casual machinist what thinking out of the box will get you... good results! Thanks for the effort you put into making the video!
1, 2 and 4 are utter chod. 3, 5 and 6 are fairly standard practice. 7 buy a die box or tailstock die holder. 8 buy a bigger chuck, 16mm Vertex made chucks aren't huge money
So, trick no.7, using shim stock to align the thread die......what happened to trick no.1?
This is for people who are not in the profession..
An experienced machinist is one of the most ingenious people you'll ever meet.
Create manually thread
Size
Major dia=6.5mm
Depth of thread=0.3
Pitch=0.720
Gradual increment=0.315
(Pitch increase per round)
Length=2.5mm
(Pitch root is round)
Angel=60°
Is this meant to be a JOKE?
I counted zero tricks that actually work !
I was thinking the same thing and dropped to the comments... thanks for your input
the business about using a dead center to set the compound was flat out weird why is he even trying to Chuck a number #2 or 3 Morse taper dead center in a 3 jaw chuck?....I don't know maybe I'm missing something?
Lazer method is not good . Use dial indicator instead
そもそも、ライトの光軸は確実に合ってるのかな?
#4 laser should be spinning
I will not agree to the laser pointer method because the laser module inside most of the time is off center and mis aligned..rather take out the module itself and mount...dont worry it has a brass casing....I have hacked many laser modules😅😅
lol, 2:31 2 HIGH
Nice compilation of tips, well done-don’t worry about the naysayers they were dropped repeatedly on their heads as children 😂
mardiiiiiiiiii
This is not the tips of a machinist, but good try
Everyone is an expert with their comments😂
You sir are amateur. When you cut threads on a lathe with a die its a sure sign you don't know diddly.
True,
But for a quick and dirty solution. CUT the guy some slack it’s a small diameter and a long threaded rod.
I’m no machinist, but I’ve had a machinist show me this one.
As a hobbyist I know it’s not the best approach, you could go to the store a buy it. But what did you learn.
Very childish
Very amateur machining. Once again couple little tricks. One good thing … I didn’t see anything dangerous. No eye or finger getters.
