Last night I attempted to change out a insert on one of my chucks. I just bought a Nova 1624 and had to covert my chuck inserts to fit. The final chuck insert would not budge. I just about hurt myself trying to loosen. After striking the wrench with a hammer and slightly rounding the corners of the nut, I looked closer through the grubscrew hole and saw to my horror RED!! This was the chuck I bought on Ebay. According to the Loctite people, the only way to get this mess undone, is to heat it with a torch to 500 degrees. HAS ANYONE BEEN IN THIS SITUATION??
Help welcome from all.
