I'm often asked 'Can you find me a new spring for my Purdey?' A bit like 'Can you get me a new hammer to replace the one I lost on my 1871 Grant?'.

This link shows you what we have to start with to make a new spring. They all have to be made from scratch.

Fantastic photo of that spring blank.

Now that could not be a blank for a single spring. They are going to wonderloaf it and make several from the slices or else they are a bunch of masochists.

Thanks for the picture Digg. How about that, looks like the bend is machined and cut out. I'd have guessed it would be forged. It does have the look like there's a bunch of steel to hog off.

Yes, Dig, most seem to think we've got boxes of springs just laying around ready to drop in their hand made gun. Unfortunately, such is not the case.

Do you have any more pictures of the Reilly round bar hammer gun that was in the photographs? I am restoring a .577 rifle with an action like that, and I have to make new hammers.

Why would anyone want to make a spring like this instead of using the traditional method of forging one spring? Doesn't proper forging leave the grain structure running longitudinally with the leaf? Perhaps the answer is the lack of skilled spring makers.

Who exactly is "we"? Have you or do you perform any of the work on these guns?

cast steel from which slices can be taken to make multiple springs from one piece?

If you look futher down the album there is a forend made from what seems a combination of subtactive technologies- EDM wire eroding and CNC machining, a combination I find rather clever.

The shock to some that bespoke guns utilise these technologies is understandable. But may be we should not confuse the product with the way it is made.

I still have my spring bending jig somewhere. Making and tempering a spring was a big deal. Then I found OMPS in Italy and got V springs semi finished. Nothing makes you like coil springs faster than making your own V springs. That big chunky "motherblock" for V springs in the pic shows that even the best makers have a hard time with V springs and try to solve the problem in innovative ways.

Why forge one spring at a time, when you can bend one large piece of stock and cut three blanks from it? That way you will have a spare when one of the two springs you need to make happens to break during shaping/heat treating..etc. Seems to me the worker making these springs is very skilled/experienced in doing this work.

The steel is cheap, but the time it would take to prepare a single spare blank down the road, is very expensive.
