Back in the 90's I bought another home which had a wood fire, the previous owners didn't leave the tools behind.
I made up a set at work and pondered which would be the best method to stop them rusting.
We had an oil bath in the workshop so I heated the tools to a bright red with a 4 burner oxy/acet torch and dropped them into the oil. (Made a bit of smoke :roll: )
Let them cool in the oil and then removed them and let them drain until next shift.
Used degreaser to clean then dried them.
25 years later there is still not a speck of rust to be seen.
Pulled them out of the workshop today in preparedness for the coming winter, they are a bit dusty but a rub down they'll be like new.

Hi Peter,

I learnt that during my apprenticeship when we did a bit of blacksmithing for tempering & hardening iron & steel.
Cheers,

Ted

Ted,
Yes, we made our own tools, chisels, centre punches etc and tempered them.
This was a totally experimental rust prevention process with mild steel no tempering hardening involved/intended.
It worked. :)




Good luck & safe travels

Yes even though no hardening was intended, as a result of doing this process to Mild Steel it has still hardened it from the process, the red hot mild steel absorbs some of the carbon from the oil bath in which it has been plunged.

As a sub process of hardening and adding carbon from the oil to the outer layer of the steel gave it the anti rust properties. :)

That's it Dave, the minor carbon inclusion has not made the "mild steel" brittle to breaking point but has definitely improved the anti rust qualities.
We used something like this to temper steel, cold chisels & centre punches. Harden them, quench in water then reheat and watch the tempering colours run down to the point and dunk them in water again.
If you didn't get it right you had a sliver of over hardened steel sticking out of you oozing blood when you whacked it with a hammer. :blink: :$ :unsure:
Imagine getting away with that in this day and age. B)

This youtube video has some excellent forging, hardening and tempering techniques, plus it's a bit entertaining at the same time. There is something like 10 episodes from start to finish of the making of this sword, unbelievable looking at the finished job.

Dave,
Will definitely sit down and view this series.
Have a machete and a knife I made years ago using car leaf springs. Been in the gun safe for years so probably looking a little worse for wear.
From memory I think it was the Crocodile Dundee movie that inspired the project.... "You call that a knife.............."

Made back in 1982, could shave with this once it was honed. Glued two of my early finds, a penny to end of handle and a threepence to the hilt, handle made from sandlewood with brass inserts (hadn't found any gold to use.). :(
