I read this in another thread:
put a turning fork in the hardie hole
Click to expand...
refering to straightening a blade during the heat treat, and just have a couple of questions.

1 Is this the same kind of fork that a musician might use?
2 How would you use said tuning fork, and for what purpose?

Just when I think I am starting to get a grasp, someone always has to say something to really confuse me! lol

My guess is that the poster was referring to a "bending fork". Looks like the one shown here.

For blade straightening it could be used as a simple leverage device....never thought to use mine for that...I'll have to try it next time :)

Just guising since I didn't see what you are referring to, but most likely the reference is to a tool which fits in the hardy hole on your anvil. Basically a square billet with a slot cut in it to make a fork. Once the blade is heated, place the blade in the fork and pried sideways to remove the bend.

Crap, I somehow managed to get two posts and can't figure out how to delete one.

It is a square billet the same size as the hardy hole, which is long enough to extend above the anvil about three to four inches. It has a cut length ways from the top to just above the anvil surface of the anvil. The cut is opened enough to allow the blade to be inserted. The heated blade is inserted into the slot and twisted sideways to pry out the bend.

AAhhhhh! Ok, light bulb just clicked on. Like many other things, same name, different use due to different subject. Just got a good laugh at my own expense, as I COULD NOT figure out how a blade is supposed to "sound"!

Thanks for setting me straight.

The "r" makes the difference between the two words.

1 & 2...No. the "tuning" fork is used to determine pitch (acoustically)

The "turning" fork is a tool used to straighten or bend metal by inserting said metal between the tines and pulling one way or the other.
 
Alright, now I really feel silly. As many times as I read that post I missed the extra "r". Amazing what just one letter can do for the meaning of a word huh?

Damn you slow and fat finger !!!!!
 
A wide turning fork is made from a a piece of round stock, bent into a "U" , and welded onto a square stub that fits the hardie hole.

A narrow fork is made by welding two pieces of round stock to the sides of the square stock.

The tools are normally used to make scrollwork, or turnings, in decorative ironwork. They are a useful tool for any time you need to bend hot steel, and for straightening warps while the steel is still austentitic.
