hi,

if i use a 2 3/8 hole saw to drill a hole in a door what will the diameter
of the circle be? (guess i should go back to high school, eh)?

thanks,

sammy

i forgot the formula...
 

um, uh, am I missing something here?

The formula is E = MC^2.

But a 2 3/8" hole saw will usually make a 2 3/8" diameter hole. The
radius will be 1 3/16 and the circumference will be 1 3/16 x 3.1415

How thick is the hole saw blade? Tom

That would be piD or 3.14x diameter

whoops. meant circumference. but i figured it out. sorry for the confusion.

thanks,

It will be 2 3/8" and the wrong size for your door knob.
Your standard door knob will need a 2 1/8" hole.

pi * d = circumference, no? (2 3/8 * 3.1415) ?

That would be d x 1
In this case, 2.375 x 1.0000000 = 2.375

Don't stop at high school, keep going back.

Actually, the diameter, what he asked for, is the width of the hole, 2 3/8".
I guess he assumes that the diameter of the hole that he drills with a 2
3/8" hole saw will be different because of the kerf.

Did he mention a door knob? ;~)

The OP asked a different question than Oughtsix tried to answer. And
Oughtsix has been out of geometry class for a while, so I tried to correct
that.

Do I still not win? ;)

BTW, Leon, nice square jig in ABPW today.

2 points for Jonny on the spot. ;~)

Thanks, the original posted jig inspired me to design one that would not
need any measurements to interfere with an accurate build.

Yep, my highschool geometry is turning over in her grave.

Your high school English teacher probably isn't doing much better. ;-)
