I don't understand the bolt sticking out thing, but when my Sears Router
jam, I did this to free it.
First I sprayed the tightening nut with a light oil, I also added oil
to all around the top of the housing router body joint. I also added
oil to the slot where the tightening bolt is
I let it set and periodically would try to move it, if it did not move I
added more oil.
After a couple of attempts and using some force it came loose. I then
wiped all of the oil from the body.
I then used a very fine sandpaper and cleaned all of the mating
surfaces, mainly the inside of the base.
When everything was free, I used an auto buffing compound on all of
surfaces of the router, including the inside area of the base where it
come in contact with the router body.
I then used a good car wax and waxed all surface I had just cleaned.
I have had no problems since.
I keep all of the surfaces of my tools waxed, ie drill press post and
base, saws, etc.
