sorry to say I forgot your user name , and I do not think I should use your actual name , but you know who you are. I got your hammer welded today. I built it back up and I ground it into shape some. I did not finish grind it because you had said you may need to "fit" it to your set up. I used pretty good fill rod and only cooled the part in H2o so you should be able to file it to the size and shape you want.. when you have it fit as you need then you can do any hardening you want. I hope you are happy with it and thank you for the return envelope it will be back on the way to you later today.
