How to straighten eyes??

[mayflyjunky]

Guys I would like to straighten the eyes on some fulling mill short shank special hooks.

Is there any way of doing it so I don't destroy or weaken the integrity of the hook???.

Thanks
Peter

Heat it with a cigar torch first

I think you're on a loser my friend,
the amount of heat you need to make it possible to straighten the eye will destroy the temper of the entire hook . . . . . . . .

This is getting real boring...lights on...lights off

Where da numb nuts do you come from...if you want bent buy bent.

You need to clamp the hook in some heavy pliers or a vice with aluminium soft jaws as close to the eye as possible, this will act as a heat sink to stop effecting the temper of the bend. Heat with a jewellers torch to cherry red and straighten with pliers.

Good luck - Steve

Is there a near total lack of understanding of basic processes in metals out there ?

The damned hook is tempered - anneal it and it will be softened - bend it without annealing and you'll either break it off clean or embrittle it ( it's called work hardening ) and dangerously weaken it .

I despair of the education system - I really do .

Go buy some American Egg Hooks !

Just send 500 to Uri Geller with clear instructions on the shape you need.

Sorry G if my post is not as riveting as the wet mays you post every day But your right, I must be a numb nut cos fcked if I could understand your second sentence.

Who mentioned anything about buying bent hooks???.

It's stupid replys like this that stop guys asking questions.


Thank you for the intelligent replys guys. I ran out of pro logic hooks but was hoping for a quick fix as I want then for the weekend. Guess I will have to wait.

No there isn't, I got a good understanding during my 2 engineering degrees, PHD and 15 years in industry .

The forces applied to a hook run pretty much straight down the shank, as long as the bend is still tempered correctly then no problem - that's why I said clamp the hook into something metal as a heatsink - so the bend won't be effected. Annealing the eye really won't make a great deal of difference to the performance of the hook. You can't apply enough force to straighten the eye out because there are no significant moments present - you certainly couldn't do it in a real life fishing situation.

Oh and work hardening raises the yield strength .
