Making new ends on recoil springs
« on: April 01, 2014, 12:40:21 pm »
I have been using a little gizmo I found at the hobby shop that makes those little circular ends on the recoil  springs. You basically heat up the end of the spring, slip it into a slot in the tool and twist the tool round to form the rounded end. It is not in the RC stuff, it is in the clock making supplies, I believe it is really intended for large clock springs. Whatever it works great, I will post some pictures perhaps Al can figure out how to make it on the cheap.

Went looking on e-Bay and found something that may work even better:

Good find.

I've been making them with regular needle nose pliers but you have to study the shape and figure just how to hold the spring to start the bend.

How about cutting the end off an old screw driver and then slotting it to fit the spring you are bending.

That is basically what the tool I got from the hobby shop is except that it is a 'T' handle. I suppose the 'T' is to give you more leverage when bending. It does work pretty well.

i always get confused. when you heat spring steel and bend it - do you air cool it to retain its springiness or do you quench it?
now is never here but the past is always present.

I might be wrong on this but in my experience once you heat the steel the spring I'd gone.   If you quench it then it can become brittle and break easy.   So I just let it air cool.   That part of the spring does not need to have any spring in it any ways.

I believe to get spring steel the conditions have to be held just right including.  The correct temp, length of time, and special quenching methods none that I am an expert in.

You are correct Roger. Too hot and quench in water = brittle, quench in oil = softer but usually it takes two heatings and two quenches to do it correctly. A really good blacksmith can do it in one heating. Heating to correct temp is critical and IIRC is actually done by color.

The "H" grade of steels always needed a double anneal.

true on the no springy need thing. so hows about regular carbon, nonspringy, steel. when heating to  bend or fabricate should it air cool or quench so as to return to its preheat level of stiffness? don't want it brittle but also want it to hold shape - say its for an "L" type bracket
