That's not an uncommon problem.
One solution is to chuck your BB remover vertically in a sturdy bench vise. Then thread your whole bike frame onto the tool and, after thinking which direction you need to turn, using the whole bike frame as a lever to remove the BB. Whenever I've done this in the past I've gotten an assistant to help me keep the bike square with the tool. The BB has always come out more easily than I expected.
Another solution is to use a clamp loosly around the BB tool and the bike frame to keep the tool square with the splines. Then find something to use for a lever arm to produce the torque that you need. It probably won't take anything huge, once you master the issue of keeping the tool square the BB usually comes out fairly easily.
Good luck.
