Hallo Johan,
Ja die hamer storie is nogal iets ne.Daardie soort van hamers is nie vryelik beskikbaar nie so n mens maak maar jou eie.Ek het n ou duoble sledge van 3 kilos gevat en sy een oppervlakte teruggesmee soos ek dit wou gehad het.Ekt toe die hele spul non
magneties verwarm en in my knife quenching konkoksie,nl Ou karolie, Atf en diesel gemeng tot n dunnerige vloeistof verhard.
Daarna het ek dit in my oond laat bak vir so 3 ure op so 200C.Dit word dan so n donker strooikleur.(standaard prosedure om messe te temper)Sover werk dit ok,maar dit is vanselfsprekend nogal n oefening,
Yes this hammer thing is an issue here as those types are not readily available.I simply took an old 3kg double sledge and forged down its one side to the dimensions I wanted.I then hardened in my standard knife hardening concotion, old motor oil, ATf and diesel mixture and baked the result for 3 hours in my kitchen stove till it showed a dark straw colour.Like differential hardening of a knife blade.So far it works.
But it is a bit of an exercise for obvious reasons.
groetnis
