    Default Metal Gate Pins Material... Also Hi (I'm new)

    Firstly Hi Chaps,
    I've just joined the forum, Metal worker in Kent, UK.
    I make prototype lighting for a living, but I've done everything from bike frames to steel buildings.
    Restore bikes in my spare time and take on the occasional Private Job to earn some beer money and buy more lovely tools.


    Needed some advice on a recent little project I've taken on to earn some beer tokens for a mate who owns a castle.

    He has a huge pair of Oak gates on the gate house which have two hinges per door.
    I have to remake (lathe) new pins that hold the two parts of the hinge together as the old ones have gradually worn down with the rotation around it.
    Now the castle manager wants a material that wont wear down as fast as say mild steel, but I still need to be able to machine it.

    Have you guys got any help of suggestions for material in the UK or Worldwide that you'd recommend for this job?
    Right I'm off to have a browse of this here forum.

    Some sort of high carbon steel - silver steel, tool steel, car axle, etc - machine in softened state then harden (temper/anneal).

    That should give a hard wearing surface.

    Or, mild steel, then case harden.

    Too hard is brittle, but I guess a hinge doesn't have much risk of shock /impact.

    But remember, if there is more wear, then the hinges may wear instead of the pin. I suspect that would be more of a problem.
    Can you provide some sort of lubrication system?

    I think, on reflection, that a replaceable mild steel pin would be better. Perhaps make it hollow with oil holes and fill it with grease or oil?

    All Russ says will work and has been tried at one time or another ! Save yourself future grief and just put a mild steel pin in there and remember to oil it regularly.

    I would just use mild steel, but i would drill an axial hole halfway through and then a meeting crosshole, slam a grease nipple in the bottom to allow for proper lubrication without tearing the whole gate apart.
