i have a stuck door on a cannonball safe. i have bolted a cheeter bar on the door to turn it, i have moved it less then a 1/8" ccw on the door. on the cheeter bar im using 3300# of weight from a fork lift. i layed it on its back and made a dam out of putty and filled the dam with wd-40 for three days, i have used a slege hammer around the top and sides with the weight on it. im pooped out. what can i do next? it hasnt been opened for 20 years +. it hasnt been out side, and no surface rust. very clean. am i right beliving that once you take the front off and combo removed, and all thats showing is one large gear aprox. 7" that after 72 hours its unlocked? and should be able to turn the door ccw and it will open. thank you.
