For those who are unsure of number and letter sizes.
The linked table should give you the sizes in imperial and metric dimensions. Print and post on the wall of the workshop.

How can I reply to that? mm - let me think....

"F-in-Workshop?" - mind your language please...

Or did you mean 0.2570inches? (6.5278mm for the pedantic). - I call it " 1/4in. clearance"...

No really there seems to be a big F on it. But I think while I was trying to get a decent picture there was an Explanation for the mystery posted. (still no idea where it came from) Yes, approx. 6.5 mm.

Steamchick,

I seem to think and operate a lot like you do in your shop when I am doing something in mine. In our worlds what matters is what fits, no matter how we get there.

As far as rambling goes: Feel free to ramble away. I read your posts.

Letter "F" drill is the standard tap drill for 5/16-18 threads and also used for clearance holes for 1/4".

What a mess.

I use 5/127" or decimal fractions of it .
Found a drill with an F in my workshop yesterday. No idea why I have it or who gave it to me?

Thank you, this will be on my wall tomorrow morning. I'll need it for my Stuart build translations and when I'm not there I'm sure the mouse will like to look at it.

I grew-up as a teenager

Well, Steam, that's seems to be the problem. As for myself, I never grew up! and if I did, I thimpfks it would have been a child -- Then a teenager.

Yes, you should drink less and not ramble so much.

From those 3 datums (dati? Datum faces?). The word is "data". Singular: datum.
