1409: Fire hydrant wrench?

Aside from your ignoring the hint page which he posted (Animal
Trap Quiz), have you *looked* closely at the nuts on fire hydrants? All
that I have seen are hexagonal -- so normal wrenches won't work with
them.

Don - I think you mis-thought Pentagonal. 5 sided nuts are oddball,
6 sided are 'normal' - for varying degrees of normalcy, of course...

Oops! You're right. The fingers are used to typing
"hexagonal", and so took control when I meant "pentagonal".

I could use some Pentagonal sockets for Edison handhole lock-bolts -
not sure how you measure them, though, looks like 9/16". (3/8" NC
threads.) Klein Nines work just fine as often as I need to open them.

Hmm ... silli-putty to get a mold of the shape, a quick casting
in plaster of paris -- or something else quick, then you can take your
measurements in comfort. I would probably try to get it centered on a
rotary table or index head, then see how far off I had to go to get to
the center of a flat side.

Then, once it is measured, time to set up and machine a socket,
which you can again test on the plaster casting.

Snip Or you could just use a Stilson!
