"If it is an internal BB then you would not have this problem and if you can get another 1/2 turn out of it then that would put it in a lot, you want to turn those old cranksets with internal BBs on pretty hard."
Just for anyone's information: Shimano 6500 is 9 speed Ultegra, which means that this is an Octalink crankset and BB. That means 36 to 51 foot pounds on the BB; and 25 to 36 foot pounds on the fixing bolt.
Using a torque wrench does indeed solve many problems, and it gives one a piece of mind too knowing that the bike is put together right! I have two: a Kobalt that goes from 10 to 100 foot pounds, which covers cranks, bottom brackets, and anything I want to attempt on my truck. I also have a Craftsman 0-250 inch pound (0-20 foot pound) torque wrench that works for stems, disc brakes calipers and rotors, Hollowtech 2 crank arms, and a bunch of other places.
I recommend using the torque specs in the appendix of one of Zinn's bicycle maintenance books, so far they've covered everything I've needed them to.
Lenaxia, keep working on your bikes! It's great fun and an important skill. Better to spend money on tools and books than to pay someone else to fix your bike.
