      Is it possible for me to grind an old screwdriver to make a usable three-point turning tool? I am not familiar with steel types and  ‘tempering’ and so on.

      Hi Jimbolisa, I threw your question out to our Facebook followers to see if they could help and so far Leon has responded. He did something similar. Have a look at our Facebook page.

      I made mine with 1/2″ silversteel from Axminster and hardened it by making it red hot and plunging it in water it  works a treat and a small one out of a masonry nail not need to harden it

      Most modern screwdrivers come with a hardened tip I should imagine a blacksmith could advise you

      Hi Jim

      Sorry for not answering sooner I’ve been away.

      Woodturning tools are made from high speed steel (well the good one’s are) screwdrivers are not, as Woody has said some have harden tips so it possible to just grind the tip. The problem however is that the screwdriver could/will bend which will weaken the steel and it will break.

      You could temper the steel as again Woody has said but how do know when the steel is up to HSS standard.

      If you want to make your own tool and know it will be safe to use I would buy a piece of HSS rod and shape that, but bear in mind while profiling the steel you do not want to get it above hand hot otherwise you have un-tempered the steel.

      If you really want to go all the way then Woody’s link will help.

      Good luck let us know how you get on.

      All the best

      Ed
