Hello folks, This Sunday will begin a week of blacksmithing at the Williams Grove historical steam engine association at the blacksmith shop.

We have several size coil springs from automobiles and trucks were gonna make punches and chisels out of it.
We will also have a sign up list for anyone who would like to come and work at the forge during the show. Teams of to work best but 1 or 3 folks would work fine also.
New membership cards are available remember to bring personal safety equipment and will see you there.

Well today was a  quite day at the forge and I got a few projects completed. Or almost completed. Made my second drift out of coil spring. This is larger than the first and I forge the tapers out nice and smooth. then I modified two pair of tongs. But the project I hope turns out well is using a large cross peen no name hammer head and making it a 45 degree diagonal peen hammer with some customization. I took a few photos of the progress. If I'm able to get it completed and not break it up, I'll post the project. Today I took it to critical temperature, twisted the peen by eye. Then I fullered the neck on the round face end. So far so good. I'll get some pics up later on the projects. It's about 2.75 lbs

We had a few coil springs with different diameters between the members of Williams Grove. So we brought them in and straighten them out and pre cut them to different lengths. I’ll post some of the work. Soon.

I like the Punch, something to thin k on when I see some Coil Springs.

Question, what metal series is a Coil Spring made of, and does it need to be hardened after straightening and shaping ?

Thanks

It's almost impossible to tell since there isn't a real standard for the alloys used.  They can range from silicon spring steels on older springs to high carbon.  Most modern springs are close to 5160 but even that isn't set in stone.  I've heard that a certain import had springs that were in the .4-5 range although I've had no dealing with them.  Always test to make sure they are good. 
When making tooling from coil spring you need to handle them they same way you would if making a knife.  In other words follow a good forge theory (start hot, end cool) thermocycle and heat treat to the appropriate temper for the tool made to get the most out of it.  

Rule #10;  "I can make that" translates to; "I'm to cheap to buy it new."

I finished today with tempering. I used canola oil to quench. I got a nice skate when using a file to test. I used bottled map gas to drawl the temper. So it's time to test the tool.

The coil came from a dodge pickup truck. Not sure about alloys or if it will last. We will see.
