  • hello looks interesting,how would lock respond to being frozen,beaten with large club hammer.
    also thinking tungston brazed onto steel could be an idea this destroys most cutting wheels on grinders, if you do not have green cutting disks,the lock body looks good ,master locks are fairly easy to break if you know how to but not sure if still easy on a u lock as have less leverage(ps am not dodgy just lived in squats for 13 years.)

  • that weighs more than my mum, but looks good all the same.
    good effort!

  • Diy Ftw

  • so how have you hardened and tempered it?
    welding will have altered the grain structure of the metal

    "also thinking tungston brazed onto steel could be an idea this destroys most cutting wheels on grinders"
    it's also very brittle.

  • Surely a punch or screwdriver etc hammered in from the non lock end of the bottom bar would either shear the padlock loop or break the metal around the hole in the locking bar pretty quick.
    What about taking a standard dlock, cutting the loop down and re-cutting the notch for the lock into it?
    Shoulda made two of em and desruction tested one yourself rather than leave it to some pikey to test when its locked to your bike.

    it's also very brittle.

    grain structure only alters if you quench, leave to cool naturally and structure stays the same. and to harden you heat to cherry and quench a few times sorted. gonna nitride it aswell.

    How if there is a cover welded on that end?

    Make sure you temper afterwards!
    Actually, what's the best temper for a bike lock? Too hard and it will be brittle, too soft it will be easily cuttable...would spring temper the best compromise?

    good effort!

    Are you saying your find you Mum attractive?...

    I am going to go with surface hardening.

  • I call it iron maiden!

  • iron maiden! very good.

  • will you be testing it against a variety of tools when you are done?

    Like these?

  • Are you saying your find you Mum attractive?...

    Everyone else does...

  • Have you heat treated and quenched? I'd say you want some martensite in there! ...
