wow, thats amateur

@scottmtm

THANK YOU!

That is exactly my point!

Threading is not that tough!

[FactoryDragon87]

Well then- this is not to my taste!!! #1- You NEED read the book through of thread cutting; #2 speed down; #3 You NEED assimilation of more experience of thread cutting!!!!

@FactoryDragon87

All I can say is LOL!

I've worked with a lot of book wielding "experts" that sound a whole lot like you.

In my hobby shop I try to show that treading isn't that complicated.

At work, inspectors don't care how you did it as long as it passes the quality control.

Mine always did. The book wielders were left to convince the inspectors why their's

should have worked.

@FactoryDragon87

My goal is to show that single point threading is not some black magic art.

It's nothing more than cutting a simple groove that happens to be moving

along the axis of a shaft.

The "experts" can maintain their need to complicate the process and keep the

speeds and feeds in the era they were taught.

I'll respect your experience and critical review of how it is being done wrong.

Please give me a link to your video showing the correct way.

When cutting threads, I understand you have you set up the drive to run the carriage, but how deep do you know to run the cutter in. I do not see anyone taking measurments.

@qualitytimerec

I go to the published Double Depth +.005

It works for me 95% of the time.

I don know why this world so many people who like to compare who is good, who is fast, and who is great. Mind yourself is enough, learn something is not to waste time for comparison.

For me I see what I could learn, that is all.

And for those who loved to show off, then is the one thing made idiot to compare.

@qualitytimerec pitch times .866, and his cross feed should be set at 29.5 degrees, which it is at approx 90

[YHTLANTYS]

The R.P.M. , please ...

Yes it works, but a slightly crude way of acheveing your goal. Running with such high feed speed that close chuck is always a abit risky. Also I suspect the finsh is quite poor and most machieists take pride in not only that they have made a part that works but that the surface finish is good.

Did I miss something a thread that small on a piece of brass would be cut quicker with a hand die.

[gavinclair2007]

I think the high speed part must have started after the video stopped or something. Lol and to all the manual machinists that say cnc is slower to make 1off parts? What planet are you from!!!!

[kikilosabeyno]

That threading technique is ok, it´s a little bit dangerous and scary but nothing wrong with it. The guy can do it this way leave him alone.

[martintfsportland]

It worked, I didnt think it would, but it did!

Thats all that really counts

@ASP1NALL #1 My lathe is simple like hammer, so then the 10kW engine not feel ANY presure; #2 I do my work without: mad, stress, stupidity!; #3 so, if YOU want crash YOUR machine at 1000RPM- You are wellcome! #4 Do You have a some understanding about cutting speeds and feeds??????

[ASP1NALL]

@FactoryDragon87 lets put it this way, the nut screwed onto the bar and he did it in alot less time- plus it probably cut alot better (less pressure on lathe motor)
