Does anyone make their own hooks, I have an idea in mind for a jig head. But cant find anything hook like that will work.

I've never head of anyone making their own hooks.   Could you bend a hook to fit your needs?

I too have thought about it, but not being knowledgable in metallurigal methods has me not able to proceed any further. I don't know the first thing about how to go about tempering the metal. :'(

You will need to find tempered hooks or be able to anneal them yourself. Forged hooks will snap when you try to bend them, tempered hooks will straighten out or bend but won't break.

Just get you a little propane torch and heat away.  We have been changing bends and eye positions on hooks for years.

making hooks seems difficult, modifiying hooks isnt that hard. just do like Jig Man said and get a torch and get the metal red hot and bend it to how you need it.

Ok, I will try to bend some. Thanks guys.

If the hooks are any good (or were) heating them with a blow torch will ruin the temper.  I have never made hooks but, I know a little about heat treating knives.  Anneal, shape, heat soak, quench, temper...  Probably way more trouble than it's worth for a hook if you wanted to make it from scratch.  If you want a specific shape you can heat it and bend it and then heat it till it glows, dip it in oil (vertical) till it cools, and then stick it in the toaster oven @ 200 for maybe 10 minutes and then let it cool.  Should give you a decent temper.

Not wanting to start anything here but having worked in the Aerospace Industry as a Manufacturing Engineer specializing in fabrication of detailed parts.

Annealing specifically refers to the process of bringing the material to its softest possible point. A tempering process softens the metal but not to the full extent possible. Annealing can not be done with a torch since it will be impossible to control the temperature and would likely result in material that is too brittle for use.

The next problem would be how to cut the barb and sharpen the point without ruining the metals temper.
