Too much pressure on it perhaps :?

Sheldon's diy tool failed on me too. Nothing else for it my friend, out with the blow torch. Screw fix do one for 13 quid with a gas bottle. I had to heat the BB up on mine with one, BB spun out nice and easily after that, almost like it was finger tight. Paint wasn't too badly scorched.
I tried everything before I resorted to this, soaked it in WD, Pus gas, chilled it, boiling water on it, hit it (the appliance of science), held the cup in a vice and tried to rotate the frame, finaly tried the hand full of penny washers and m10 nut and bolt route, nothing shifted it!
Meanness prevented my buying any more tools, apart from a gurt big adjustable spanner at a car boot yesterday. I used it to create what is now called the Chris667 (tm)(c) fixed cup freeing tool.
One high tensile bolt, 1 nut, 3 washers and a 12" adjustable spanner.
Spanner was clamped over the flats of the fixed cup, then bolted down. Hard. The spanner then became a lever to unfasten the cup with.
This won't work on one of the more modern fixed cups that has flats on its edges, you'd possibly hurt your frame.

lots of dismantling fluid days before, then put the flats in an engineers vice and tighten with brute force so it cant slip and turn the frame. Never failed me yet.
and sorry if you already know this, but euopean threads turn the other way to english for the fixed cup.
however, I do have probs on one frame getting a sealed shimano unit out (the type with splines). ive already buggered one tool up on this.

I'm sure you know this, but be careful with that sealed BB! Once the splines are gone, it will be a git to get out, you'll need welding kit.
What I do is use a thick, heavy washer, and use it under the crank bolt to hold the tool down on the BB. Again, it needs to be tightened down hard.
