Threading set-up

[Lucky Shooter]

While we're spending time on threading-----how about a thread on methods of aligning the tool tip vertically.

Should also apply for other cuts.

I'll be back with my crude methods.

Here is how I do it. Much easier to paste Joe's video than to write it all down here.

My work comes out better since I made one like his. For me, a razor blade or eyeball works better for me that a fingernail.

 

[Lucky Shooter]

A carbide-tipped center is put into the spindle and the tip of the center is used to scribe a line on
a piece that is standing flat on the carriage.

This piece with the scribed line becomes the gage for setting tool tip height. Once this gage is made,
tool tips can be set by rotatong the tool post to allow vertical adjustment of the tip. This can be done
with a work piece in the chuck.

This is a visual exercise and is subject to the user's visual capability but has been used for years.

I'm open for a more precise method but it has to be simple.

Put a live center in the tailstock. Rotate the tool to set height to the centers tip.
Or, chuck up a piece of stock, face off to the center, set tool tip to the center.

I just bought one of these. Works great!

Just ordered one, along with a few other gadgets from ET products. Seems ordering direct from them is about the best price I could find.
Their mill tools, tramming gauge and indicator holders are great.

After a while, one can eyeball it on center but in the meantime, down and dirty quick way, take a solid six inch scale, stand it up against the workpiece and run the tool bit tip up until it touches. Top of scale tilts toward you, bit's too low. Top of scale tilts away from you, it's too high. Scale is vertical, tool's on center. Unless parting, skosh low isn't going to hurt anything.

Edit: Found this video.

I've used the method Hogpatrol suggests for years, and haven't ever noticed any adverse effects.

I used the 6" scale method for years. Made a Joe Pie tool and checked the scale method against his. Surprised the sh*t outta me....
Once the time was taken to make the height gauge, the rest is quick, fast, and in a hurry. Didn't have to $pend to get a gadget.

Any way that gets you centered quickly is OK.

I've always done it like Hogpatrol suggests. After watching video he added, I have always done it on what I was working on...never thought to use smaller diameter for more accuracy.

 

[TAJ45]

I feel likadummy. I have used HPs method for years but never thought abt the smaller dia being more accurate.

When X axis depth is no consequence, kinda like turning the compound to 1° off of parallel to axis, do the trig and every .010 = x tenths of dia. Of course depends on if the compound is 2 fer 1.

I have looked at these. I made a similar one that sits on a 1" diameter TG&P piece of stock. The Edge-Pro-Lathe-Gage looks like it could be used upside down to set an inverted threading tool.

I've used the method Hogpatrol suggests for years, and haven't ever noticed any adverse effects.

Just be careful pushing a carbide tip against the scale, it will chip. Ask me how I know.

I guess I'm the only old dinosaur that basically set's tool's up old school grinding my own.LOL

 

[hogpatrol]

And checks the 16 pitch on a Remington tenon with the same fishtail. (or an inch scale).

Count me in as well For what I do Ill take a good homegrown HS steel tool almost every time
