I want to try to make a torsion spring for my old shotgun.
Just wonder where can I buy a music wire in GTA or Internet?
Thanks.
 
Any hobby shop that sells model airplane items. They normally have at least 30 different sizes. You can also pick up a hand spring winder off Ebay and they work like stink. I'll get you the name off mine when I find it. I've used it to make dozens of coil springs. You can also get wire bending pliers on sale at Michael's craft stores and you can make hair pin springs as good as any you will buy.

All but the lightest sizes are over wound so that won't work. He needs the thicker sizes of wire.

Another vote for a hobby shop that caters to model airplane or model railroad hobbys.

For small diameter stuff you can make a bending or coiling jig to wind the wire around for making a torsion spring by simply driving nails into a hunk of good quality plywood. Note that the smaller sizes have a LOT of spring back. So you'll need to play around with some different nail sizes to get the diameter that springs out to the final diameter you need. Same with the amount of over wind you need so that the arms spring back to the final desired angle. This testing produces a lot of failed attempts since there's simply no way to calculate how much a given size will spring back when wound around any specific pin diameter. So buy a couple of 3 foot lengths so you have lots to play with.

Wear safety glasses with good side protection as well. If you're working with long lengths so you don't waste any the free end whips around like a cobra on speed and you can get injured VERY easily. A little blood leakage isn't a big deal. But the ends seem to get radar lock on our eyes all too easily. Been there, done that and glad I thought to put on the glasses.
 
Thanks a lot.
This is what I want to make.

Your old shotgun most certainly does not use the spiral wrapped springs you show. That's a method used by Sig and maybe a rare few other makers.

You'll want to use some calipers to measure the size of the wire of the present broken spring and buy some that size and one a size bigger. Then you need to play around as I said with different size nails as stop pins and winding pins.

Get some small 3/4 finishing nails as well. You'll put one of those into a piece of plywood alsmost all the way down to the face to just catch and hold the wire so it sticks out to form the one leg. Then the center nail sticks up beside it. To wind the coil put the wire between the two and pull it around the tall nail using the short head to hold the end. Make the required number of turns and play around with a little more or less until the legs are at the right angles. Then cut off the legs to length and add any other features.
 
I'm pretty sure he pulled the picture off the web simply to show the sort of thing he needs to make. Tell tale signs being the white background, excellent lighting, lack of cheezy looking floor treatment and most of all no feet in the picture.... :D

The wound wire yells Sig to me. But other outfits might be using the same trick. So they might just be the springs you think they look like.
 
The wire that comes from the tool stores is in 1 lb coils and it's WAY more than any one person needs in a lifetime. Also he doesn't know what size he needs since self made springs don't tend to be quite as resistive as factory springs because we home springers don't do the heat passivation trick like the factories do.

The hobby shops and the 3 foot lengths they sell for a buck or so per length is still the best bet for a number of reasons.
