sten pawl spring

hi all

anyone know how long the wire is before its wound into a pawl spring ? I know the wire is 1.6mm o/d

been looking for info in various places

thanks

You can't just use a short wire to wind springs, you'll need enough to hold onto. Use a full length wire so you have extra. Then cut it off.

hi, yes ive got some piano wire

Then you're ready to start at least...let us know...

The pawl spring isn't a spring as such, in that it doesn't 'spring' anywhere. It is just a hook that acts to elevate or keep the sear elevated into the path of the breech block. And it does this by being tensioned by the trigger spring. So any suitable wire will do! You could start by simply annealing a clothes peg spring. No need to harden and temper afterwards - as it's not a spring!

hi peter, yes I looked at that but all the ones I can find are too wide to fit, thanks tho

Well after you have tempered it to red heat and allowed it to cool naturally, just unwind it until it's not too wide! Necessity is the mother of invention and all that........... But the basics of what you want are there.

well first attempt not so good , someone suggest winding around a nail, ok doesn't work. going to follow this I think next time

I've actually unwound M16 springs and re-used them once re-wound.

Philb........ You REALLY are making a mountain out of a molehill. You are looking for something that is simplicity itself to make. It is NOT A SPRING you want, it is a piece of shaped wire

yer, we not all engineers etc

quick one I knocked up out of a clothes peg spring

Does it work then?

Just do the same again but reduce the coil part by one complete coil. It's not a case of engineering Phil, just simple use of two pairs of pliers and the gas hob in your kitchen
