Hello, i'm new to this site so i hope its alright to post this here. I own a saw shop in Ellsinore Missouri and i do all repairs on inserted tooth saws, I hammer and tension the saws on a padded anvil, strech/roller, this process puts NO dents or dings in the saw and gets the tension of the saw alot more accuratley. I also replace tips, and backs. My number is 573-322-0166, if no answer please leave message, thanks.
