I had a BB frozen in a titanium frame. It had been stuck in there since I bought it second hand
(D'oh). When the frame cracked around the BB I stripped it down and had it re-welded but had to
leave the BB
in. It was re-welded about three times. What I'm trying to say is that this thing was not just
stuck, it was ssttttttuuuuuuuuuuuuuuuccccccccck. This POS frame was actually a pretty good ride
and so when the BB finally started to seize up (after about 5 years that I had it) I took it to
Dave at the LBS to see if he could do anything. Clamping the BB and turning the frame managed to
free up one side, leaving the spindle still in the frame. I was asked if I wanted to leave the
room for the 'delicate' operation to continue. Slightly unsettled I declined. Dave got a hammer.
Not a small hammer to go 'tappity tap tap' on the shell, but a bloody big lump hammer. He then
pounded the sh*t out of the spindle until finally it flew out the other side, leaving just the
cup in the BB shell. Instructions were issued to go home and carefully hacksaw the remaining cup
into quarters and prise it out, which I'm happy to say I
You may want to exercise caution when using the Dave R. method on a 4 year old aluminiumm frame....
