Yesterday I spent a whole pile of time for nothing a total waste.
I was trying to get a 062.5 taper set on the lathe and it takes awhile with a dial indicator.
But by darn I did it right on the money I was so proud of myself.
Now to cut the taper so I can have a quick set up device for something.
I did that and now I am ready to do what I need to do.
Once that was done I checked the work and it just wasn't right.
Nothing seemed right and it was bugging the devil out of me.

Today I went back and read what the dimensions were and it hit me like a ton of bricks.
I feel like an idiot.

Here is the deal.
A pipe taper is 3/4 or .750 per foot.
Divide that by 12 and you get .0625 great now set up the angle with a dial indicator.
That is where I goofed up.
That dimension is diameter per foot.
What I should have done is divide .0625 by 2 to get .03125.
This will give me an angle of 1° 47'.
What I am doing is cutting pipe threads without using a taper attachment.
Sounds crazy but it works, I did it yesterday with great success but the angle was twice as much as it was supposed to be.
Pictures and explanation coming soon.
