America has reached 250 years, and I am grateful to be here, in the best country in the world. Thank every one of you who helps make this country a better place, those who have gone before and risked it all, and those who've paid the ultimate price to make the United States what we are today.
Happy Birthday America! Let Freedom Ring for all time!

No...
I rotate them so they are flush on the inside and outside of the eye (centered within the 'eye wall'). I don't remove them, I just don't 'use' them.
Since the handles (hafts) are designed to slide when thrown to help in not breaking the haft, I just have the haft 'friction fit' to the head tightly. After fitting the haft to the head first, I heat the head by itself to 200 degrees F for 20 minutes, which opens up the eye. Then I slide the haft through quickly while the head is still hot, and sharply tap the top end of the haft with a rubber mallet to 'set' it in really tightly. After cooling the eye shrinks again, so it ends up really tight.

simulating approximate size of the eye and simulating its round not oval just for the sake of the math.
If the eye of the hawk were 1" round. it would have a length of 3.14159" circumference, taken that the coeficient expansion for steel is 0.00000645 in/in/°f. (some references show 0.0000073 in/in/°f)
Assuming that the head actually reached 200° in the 20 mintues, and the ambient was lets say 70 for a real extreme temprature differential.
Your "eye" grew, a grand total of 0.00263". I don't think it got you a great deal difference to fit the head on super good.
This is really sloppy, and would not be completely accurate, but i think if anything a real hawk would expand even less than a rough calc like this would show.

Regardless of your numbers... the haft slid further into the eye after heating... enough to tell an obvious difference. I am not sure where you get the idea the eye will only grow .002" in circumference. I think you are underestimating greatly. BTW, the eye is quite a bit larger than your estimate, too. The eye is 'egg-shaped', and is about 1" the narrow way... close to 1 1/2" the long way.

i think you are both right.
the Cold Steel Heads' Eyes have something ridiculous like 1 degree rate of change from one opening to the other.
a little expansion, such as brother 'm80- observes (beautifully, i might add), seems to me like it would allow quite a bit more longitudinal movement when the haft was replaced in a hot hawk head, because of that very small amount of taper in the eye's interior.
if it works, it works.
good enough for this vector!

In the previous post, I was at work... so I gave the eye dimensions off the top of my head...
The following measurements were actually taken from my own Cold Steel Frontier Hawk...
Top of eye
Front-to-back: 1.425", side-to-side: 1.05"
Bottom of eye
Front-to-back: 1.35", side-to-side: .975"
Height of eye (top-to-bottom): 1.30"
From the centerline of the eye opening, that would be a change of .0375" in 1.30" toward the front or back, and .0375" in 1.30" toward either side, also. That works out to an increase of about .0288" per inch vertically from the haft's centerline.
Someone with more time than me can do the calculation for the actual degree(s) of change from those numbers I have given... if anyone cares to, that is...

That scares me...
But somehow... it seems OK...

And here I was just wondering when the coefficient of thermal expansion was going to pop up in a thread
I actually expected it in Prac Tac

yep.
it's a geekdom solar flare or some goldang thing, brother.

roger that, on the cold shower, brother johnbar - i've been handling a swarm of BUGs all day, and i have taken two cold ones already... Miller Genuine Draft showers the insides nicely.

If you drink some Mad Dog 20/20, you could shower the outside, too... with chunks...
I have already modded one Trailhawk last year but i recently made a CS hawk bulk buy from Jay at Warriors and Wonders in Vancouver.
Went halfs on the purchase with a buddy of mine.
2 trailhawks, 2 norse hawks, 2 frontier hawks.
3 each, woohoo! I will be a modding soon!
Noticed something unusual though, one frontier hawk has the set screw in the side like with the Trailhawk but the other frontier hawk has the screw located in the back like on the Norse hawk.
Where on average are the Frontier hawks set screws usually located?

Hmmm...on the side, or on the back.
i know, it makes me crazy too.

So its totally random or based on the phases of the moon/Chinese astrology or the variable mood of whoevers running the machines that day at the CS factory, LOL!
