The small coni spring eye problem is one I've heard from time to time on here. I was adding a second spring to some #110s and I couldn't set them not even the first notch. So I compared a #110 spring to a #120 spring and I located the issue.

This is what a #110 spring eye looks like

A little bending and it fixed that problem, but I still couldn't set the trap
I looked closely at the pieces and how they were moving against each other and had an idea

This is the problem. The spring eye would seat right against that flat end of the jaw

With the angle grinder I fixed that problem also

So I think those conis with the small eyes that are hard to set can be fixed with a few minutes and an angle grinder

Let's see what you've come up with

I did the grinding to my bridgers years ago. Worked like a charm

The last batch of springs came already centered properly, but the first 4 dozen needed bending. This will allow for narrower box slots.

Bridger 330s are notorious for those little eyes. I talked to a guy at Bridger last year and asked him if they were going to fix that issue and he said the new ones will have the bigger eyes. I haven’t looked since. Have they fixed it?

I am selling the bridger 155s I have because the safety hooks and so wide you can't set them by hand

I use setters for everything except 120s

Experiencing same problem of being neigh on impossible to set the 120's, thanks for the tip
