Chainsaw Repair

I was wondering about something like this since baileys sold all those woodland pro breakers and spinners in the past and now dont sale them or the  replacement parts for them. 

I had thought about checking with someone like Al Smith on making a punch (but knew his lathe was broke down).  Was wondering how to make the punch tip hardened and it looks like your idea takes  care of that too.

Thanks for sharing with us and I will test the punches out in the future too. Thanks.
