This guy could go to work in a well stocked machine shop and convert the whole thing into a pile of scrap iron within two weeks. Tops...

The wobble in that drill press is glorious

[kjoyner]

Well, first the trick of putting the round stock in the lath chuck this way is way too dangerous, next the flex of the workpiece and the tap is noticeably excessive, and the taper of the tap prevents it from fully engaging the workpiece all the way to the end. You can see from the Prussian blue the threads are not the same all the way. When he threads the nut on, it is really loose at the beginning and stops before it gets all the way to the end of the threads.

But...WHY, he seem to have a thread''feed''on that lathe anyway. Why not just use a 60 degree insert or grind a HSS

[RMancilla]

The finish on that round stock before he even started the threading process told me everything I needed to know.

[vandalsgarage]

There are a couple of things working against him. He's trying to compensate for the taper on the tap by running it well beyond the end of the threads on the workpiece, but the workpiece still is winding up with a slight taper to the threads.

I think a bigger problem is that the threads closest to the end of the workpiece are engaged the entire time the tool is cutting, while the threads on the end are waiting for the cutting tool to arrive. If it takes 12 revolutions of the spindle for a pass, the first thread will be cut 12 times _more_ than the last thread. Whereas with a single point tool, each thread is cut once for each pass.

It's called a TAP, not a THREAD DRILL.

[mehmettemel]

That's a total waste of time there is too much surface contact creating flexing and a very rough finish.Surely you would have a piece of HSS to sharpen a single point tool and cut the thread much faster and better finish.A little lubrication might help.BTW it is not a thread drill it's called a TAP.

[bobroth]

I've been a machinist and toolmaker for 49 years and this is the most asinine thing I've ever seen. Forget you've ever seen this

[donwest]

the "device" you're using is called a "TAP!

[jamesbushey]

Why not just use a 60 deg threading tool?

[cameronmccreary]

Listen to that knock, knock, knocking sound at 8:00 while the part is turning; the bearings are ruined in the main spindle of the lathe.

[nevetslleksah]

Crude way to cut a thread. But you got lots of people, including me, to watch your video so you got some money from YouTube. Carry on.

[mikeblankenship]

You're crazy to hold that part with your hand while drilling

[glenndwyer]

C'mon give him credit, it's a proof of concept, I'm a 2nd generation machinist been in the trade for, 32yrs qualified, and even longer before I started my trade, and I think it's great,

[tranhoacao]

Tiện ren như vậy thật là một ý tưởng điên thức tế chẳng có một thợ tiện nào làm như thế này cả

[Michel-Uphoff]

"Watch and learn.. amazing!" Wow??
What I learned is, this is amazing nonsense.
Single point threading is the way to go if you don't have the right threading die.

[danneumann]

this is so stupid. Use a threading tool. If anyone thinks this is a good idea, they dont understand machining. The tap will flex further at the end and a thread mic will reveal that the pitch diameter is smaller on the end of the part as this tap flexes. Machinists have to make parts to a drawing so that it will fit other parts that are not in our possession. when cutting threads, we can not check with a nut or a bolt, we must check the pitch diameter with a pitch mic or a thread gage.

some of these trick are fine if you are fixing Your tractor, but not for doing real work for customers who rely on Your parts fitting into mating components . Please understand threads and what the minimum and maximum tolerances are and once You do, You will not attempt these kinds of methods.

We respect and love You guys, You are fellow metalworkers. Please up your game. It costs nothing and will make you so much better. Try using cutting oil for starters. Try indicating Your work instead of the wire method.

[chetmcmasterson]

How is using a tap here better than a threading insert? You've still got to have the machine set to the correct number of threads per unit length, right?

[mikem]

I dont see the advantage over just using a standard threading tool
