Hi everyone. Just wondering where I can buy needle springs for my clarinet where the ends are already flattened? Thanks

Windcraft don't have springs already flattened. No supplier that I know of has them either, since the lengths vary, and the amount of flatness is also different.

I have springs but I don't know how to flatten the ends. Can anybody tell me how they do it? Thanks

You take a hammer and flatten them out. You don't have to flatten them much. Then you just take a pair of wire cutters and install.
That is the easy part. I hope you got the broken part of the spring out of the post already.

Musicmedic.com sell a nice pair of pliers specifically for this purpose.

I tried flattening them with a hammer on my husband's vice, but my hammer and vice must not be flat enough. Is that the trick and then having a really flat surface to hammer on?

You can buy flattened-end needle springs "D80" from Ferree's tools. These are not blued springs and do not work well for professional application. These springs are used on some student clarinet brands. Springs are sold in different sizes so you need to know the exact size you want.
To install a spring is a piece of cake. To remove it - is another story.

To flatten a spring, I use a pair of needle-nose pliers to hold the sharp end of the spring, lay the end I want to flatten on a flat jeweller's anvil that's held still on the workbench with a C-clamp, and bash the end of the spring as hard as I can with a small but heavy steel hammer with a flat head.

That's roughly the idea.
I have a nice curved edge to my anvil, so that I have more control over the process and the exact shape of the flat.
IMO the shape of the flat on the Ferrees stainless steel springs is poor. The alloy of stainless also seems poor, with too much friction inherent in the metal itself when bending, and too much friction on its surface where it contacts the spring cradle. IMO the springs from Kraus are far superior, but unflattened, but Kraus does not sell to the public. I suspect this may be a source for the same thing http://www.smallparts.com/products/descriptions/swgx.cfm
I doubt that many good technicians use pre-flattened springs. Seriously, the flattening process is not a big deal.
