Edge size before hardening

[Chris Leahy]

When you say half inch , two inch....... i can get picture in my head of that .But when you start with that 1/16 , 3/64 and something like that I m lost .When someone say it is 7 mm. thick I have picture in my head of that and I can find around something that is approximately of that thickness.I always wanted to ask you , when someone say to you ............this is 7/64 do you have picture of that thickness in your head ? I ask this seriously

Pretty darn close, but I can’t speak for everyone.

As someone that spent a large part of my working life in construction, I might think of it as a “c*** hair less than 1/8”

Not to be unnecessarily crude or vulgar in my response, but this would literally be the most commonly voiced way of saying it by most of the people I worked with, and so of course I did as well. I still think it when working on my own. You can’t do that day in and day out for years without it
becoming part of your mental process. I don’t usually say it out loud in minded company though!

4ths, 8ths, 16ths, 32nds, and 64ths of things are a daily part of life when measuring and cutting for a living, as is the c-hair more or less expression.

When measuring for a cut, if you wanted a c-hair more you might also say “leave the line” meaning to cut in such a way as you leave the pencil line visible on your workpiece.

So the shorter answer is yes. I can picture 7/64

Brad at Peters wants Stainless at a minimum of .010" to .015" for HT.

It's all just a matter of what units you are used to. I have a hard time visualizing 1mm, 2mm, etc. Even though that should be easier than 9/64ths. But on this side of the pond (so to speak) the inches are what we 'Americans' grew up with.

I see things in thousands of an inch. All my hand scales have a side that’s 100ths. But my pride and joy are these bad boys.
When I have them out I feel like I should hire and armed guard to watch them. People always come up and start playing with them. I tell them if thy drop them thy bought them. Oh ok that’s fine. I say is it, can you afford that? Oh thy are not digital so thy can’t be that expensive. Thy always gently set them down like thy just picked up a bomb when I tell them thy are over $900 new lol. All the sudden thy don't look fun to play with any more. But thy are actually quite fun to use. So thing about being able to read to a thousandth on a analog scale. And thy have the metric scale on the top.

On my 1084/1075 blades I leave the edge around 0.015-0.020 before HT.

Getting back to the original question.

 

[TigFur]

OK, we probably should quit cutting up now. Apologies to TigFur for getting away from the question.

No problem, this is quite fun.
If even one person learns metric because of this post it was worth it.

The way this sounds i have hard times imagining any american working precisely

and then theres this extreme Nice piece! i was angry when i found out the normal ones cost around 100$ amd not 10 as i thought... except the cheap china ones which have bad precision...
but 900 thats a little bit extreme.

But i also thought itd be cool to buy an xrf analyzer even if it were to cost a 1000$. Turns out they cost around 20000$... too bad

...and yet we do

Although we do occasionally miss a planetary landing due to not knowing the metric system.

I always get really annoyed with myself when I mis-measure a cut by one planetary diameter ;-)

I keep cutting and cutting and its still too short!
