What you think so far? 5160 blade forged to shape then belt sanded to as flat as i could make it with what i have. One problem I'm having is the tab curves in a little too much when opened its a little wobbly even with your hand holding on to keep it open. Any advice how to fix it? I am thinking best solution is forge a little more in that area and try drawing it out.

By tab you mean tang?

Either move your stop pin, enlarge your stop pin, or adjust the tang.

I wouldn't draw it out. you need that tang to be dead flat.

If you're going to have to adjust the tang heat it and bend the tang in the direction you need to.

Yes leifjl I meant the tang that protrudes when the knife is shut. Wasn't sure on terminology of it. If I use a bigger stop pin. I will have to adjust the closed position as well right?
 
How bad do you think it will throw the blade out of line when open though? and how would i fix that?
 
Did you make a working model before hand? It could be paper /cardboard/wood.This is how you work these type problems out.First the model then the steel.

How bad do I think the spine of the blade will be out of line with the handle when in the open position?

If you use a larger diameter stop pin to remedy your original issue, then you're going to have to adjust the tang area that rests against the new pin and the area where it rests when closed.

And, yeah, as gredpe3 said, this is much easier to work out in wood first. I use plexiglass too, but same difference.
 
I did use paper after I forged the blade to shape. all seemed ok until i went to put the handle liners on it. Its my first friction folder and i did study all the research I could find on it. One thing I found that is the most vague on all i searched was pin stop placement and shape of the tang varied from one maker to the other.
 
Do all your dial in work on the model.Its easy to make a new blade out of paper.
