List members; I have mixed the 50-50 mix of Acetone and Trans fluid. I had a especially stuck bar stem and it was a rare Schwinn unit in an old Continental frame. The frame was so bad I used the blue wrench to just cut the fork off the frame. Trying to save the bar stem and fork for it was chrome I used the 50-50 mix. The stem and fork broke free after a long period of soaking many many days, but the bar stem would not come out. The death of the bar stem was evident and after clamping it in the vise and much work I saved the fork and found out why, the bar stem went all the way down to the bottom of the fork and would have been nice for a higher rise on the bars. It would never have broke loose without the 50-50 mix.
