My Father-in-law just gave me an old 22lr revolver that was his Dads. There is no brand on it and it has a broken hammer spring. Is there any way to build one?

Thanks

Can you throw up a picture of the revolver and the spring. Might have one.

Short answer is that, yes, a new spring can be created.

Look at all factory possibilities first is my suggestion

Making springs is not actually difficult, but you MUST know exactly what you are doing or it
will take a set quickly or break. No magic, but a good bit of knowledge of alloys and heat
treating is required to do it properly.

Try to find a factory replacement, or find an OLD gunsmith that has been doing it for a while
and have him make and heat treat one. Of course, if you find a young gunsmith that has
been to a good school, he may know how to do it, too.

Here are some pics of the gun. The symbol on the grip is the only identifying mark I can find.

Not sure what make of revolver you have, imported , no doubt. Flat springs are actually simple to make. Nice if you have the broken origional to follow but there should be enough to wing it if needed.
Brownells has flat stock in many dimentions, this will help in the shaping. The heat treatment is the real bugaboo in spring making.
Too hard, it breaks, too soft, it bends. A furnace that is pyrometer controled is the best way to go but you can get by with Tem-a-Lac liquid or pencils to get close and it will usually work.
Google small, flat spring making. There are a lot of ways and ideas out there.
There is also info in the Brownells catalog.
Also, try to make over an existing spring.. Keep all grind marks running the long length of the spring. Any cross scratchs or grind marks will cause it to crack at that point.
Give it a shot. It isn't actually all the black magic it is made up to be.

If you want to try, I can help you with the heat treat, as long as you recognize that it may
fail the first time when using "rough and ready" heat treating measurement methods.

Get a piece of spring stock from Brownells that is the proper thickness and carve out the
shape, then file and grind and polish out all tool marks, and make the edges very smooth.
PM me if you want to try it.
