I have a dough hook that is completely stuck on the stem of the mixer. I tried the compress and hot water. No luck. I tried pretty much every online removal method I could find with no luck. I disassembled the chuck and have it off and separate from the machine. I managed to hammer the stem down but still can’t get it to turn so it will release the hook. I ran a punch through the hole at the top of the stem to try to turn it. It broke the punch lol. I’ve tried pb blaster to loosen it and that hasn’t worked. My last two options are going to be boil it and try to turn it, or put the hook in a vice, torch the heck out of the stem, then run a rod through that top hole again and try to turn it with the torch on it. If you have any better advice, please let me know.
