Econemy Thread Wire's

In the trade I worked in the Hydraulic department turning cylinders for heavy equipment. Reading the wires was not hard... it was getting the darn things to stay put! I used a little gob of heavy grease to hold the top wires in place while I held the bottom tto the mic. Of course the cylinders were 6 to 9 inch diameters 12 TPI.
I like the rubber holder gizmo. My Pee Dee's didn't come with that.

There are many here who have never used thread wires.
Sounds like you've used yours several times.
Please consider giving us a how to primer on when, why, and how.
I wonder if the presumed complexity scares prospective new users.

I don't recall using them before. Used other gages to measure threads, Go-NoGo and pitch gages.
 
I'd like to have a nickel for every time I have used thread wires. LOL

clean threads(acetone) gob of modelling clay.sticks to threaded part stick the wires in.
 
I would think that for the average hobbyist the economy thread wires would be good enough. I am sure they have to be within reasonable tolerances. As for holding them in place I have used the cork method many times and the micrometer adapter a couple times.
 
If you're really lazy (or having a tough time holding all 3 wires) do a little math and come up with a target size based on contact with the major diameter on one side and 2 wires on the opposite.

Me too, Bill......me too.
 
Yeah, try checking a 4 pitch Acme thread with three wires... You find out real quick your mic is not big enough, spindle diameter wise, to get it to straddle the wires. I use the one wire method in its place. Two wires work too.

Yeah the wires and holders are amazing, it's just the table of data that came with them is wrong :) the box is a bit poorly molded so one size can get stuck a bit.

Would using just 2 wires on one side work? Seems like it should be the same after figuring out what the dimension should be, if a sample thread was available it should just be a comparison type measurement. What say Ye?

I think the reason to use 3 is to get the measurement parallel, if you were using just 2 (one each side) their would be more risk of measuring them at an angle other than 90 degrees to the thread.
