I recently learned a really useful trick for removing rusted nuts and bolts from an old gunsmith that I thought was worth sharing. I have already used it three or four times with great successs. First, heat the nut with a portable torch. Get it to almost the point of starting to turn orange. Pour cold water on it. The shock causes the bolt and nut to release. Of course you can't use this in every instance. Below is the story behind the gunsmith's learning of this trick. The gunsmith said he learned it the first day he was hired to become a machinist apprentice. He said the boss told him and three others to go out to the yard and to disassemble some rusted dozer tracks. At lunch they still hadn't removed any bolts. Two of the boys left for lunch and never returned. The other at his sack lunch and then wen't back to work. At about 2:00 the foreman came out and asked how he was doing. He said he hadn't made any progress. He told the young man to go get the torch and a bucket of water. He said to heat the bolts to cherry red and then pour water on it. He tried it and had instant success. He asked the foreman why he didn't tell him earlier. He said I accopmplihshed two things. First, I got rid of those other two boys who didn't have the right work eithic to stay and I taught you a lesson you won't ever forget.
