I am looking for a trigger spring for a uberti yellowboy model 1866 carbine.It is the old style with a two legged spring held by a pin. I have searched the web and contacted many places like vti,bobs gunparts and several cowboy gun part businesses, with no luck.
If anyone knows where one can be found please reply.

Brownells.com lists one:

It doesn't look like the one you want from the picture, but they don't always show the right one.

Thanks Willikers, I've tried them and about every other parts supplier. I think I'm just going to have to find the right person with one laying around or a gunsmith willing to make a difficult spring.

Ok, I'm convinced.
I need to learn how to make springs.
Wish me luck.

Good thing to learn. When you get it down, I have a challenge for you.

Judging from the youtube videos you can do it as easily as anyone.
The apparent trick is to use piano wire and avoid the heat treating and tempering associated with normal wire.
Measure the thickness of the original spring and compare that to the chart at:
http://www.pianoworld.com/pianowire.htm
One video showed using a strand of steel cable, instead.
Then watch how the wire is wound on the youtube videos.
About all that is needed is a drill, a home made mandrel to wind the wire on and some practice.

To use regular ole' wire, even the heat treating and tempering doesn't sound all that complicated.
The instructions were:
How do you make a small coiled wire spring?
To get the wire to take set you'll need to harden and temper the wire. Start with the hardening, heat to red for a few seconds and quench while it's still hot. The quench is oil, water (brine), or air, depending on the type of steel- if you're not sure use brine (salted water). Then polish the wire to be able to see color again, and temper to dark blue.
But they left out whether this is done on the finished wound spring or on the wire before making the spring shape.

In 1994 I saw a gunsmith fix my grandfather's break top Iver Johnson revolver trigger spring with a piece of one of my guitar strings.

My father, chief engineer gun designer, just made a sketch of a spring and Renton Spring and Coil would make a free prototype.

I am somewhere in between, and try to find everything with Google.
