Spring for feed system

[Skoad]

I need to make a spring feed system, very similar to those found in semi-auto pistols. In fact, a spring from a zeus pistol would work perfectly.

Problem is I have no idea where to get one (besides buying some 20 dollar part kit). Anyone know the strength (or whatever its called) that I would need. Or if you know where to get JUST the springs from something like the pistols, that would be great too.

I used the spiral binding from a notebook once.

i went to my local hardware store and found one that was exactly it in about 5 min

Either Home Depot or Lowes carries a few springs, I can't remember which one, but I've never really looked into them cause I haven't needed one (yet )

I checked out lowes. They had one that was perfect in diameter but it seemed like it would be way too stiff. Not sure if it was "ball breaking," might have to give it a try.

For my cutom sydarm I used 3 very light springs with two little tubular peices to hold them together.
