First threads!

A set of wires is usually less than $20US.

That would be about 30 bucks up here and would need metric too
Seems affordable will give them a try
Might have to brush up on my math
Thanks for the post

I don't think you would need metric, just the chart that works. The idea with thread wires is that they are a cylinder of a known diameter that touches both sides of the thread at a known depth (due to the diameter). 1 set of wires should work for all threads.

The wire needs to be small enough that it touches the side of the thread, and large enough that it can be measured over the crests, right?

Thanks you cut my purchase in half
Any idea where I can get a chart?
A bonus too all my mikes are imperial

This set of 48 wires (all imperial) comes with a laminated copy of the chart for $23! They also have it about 1/2 way down the ad in picture format: https://www.amazon.com/AccusizeTools-Metric-Thread-Measuring-EG06-1001/dp/B01AUZNSH6 All dimensions are in inches which makes it that much easier

Over all good reviews except the case
Thanks again for the info

The wires are standard agnostic.

Wait, which formula is for cross slide feeding and which is for compound feeding?

Dave, use 0.75/tpi when feeding with the compound. For feeding with the cross slide, use 0.75/tpi X 0.866. The 0.866 is the cosine of 30 degrees, which is close enough. I got it turned around because I'm remembering all this threading stuff off the top of my head.

Awesome! I was vindicated!!!

Of course, I learned a LOT from you! Thanks!

I think the Accusize and Shars mics are identical; so is the price. They should work just fine.

I ordered the Shars thread mic. It was a little quicker in shipping and a tad cheaper.

Nobody's perfect and I'm old enough to know that I'm not perfect or always right. Thing to do when you mess up is own it.
