Boy, you scared me there!

I have a number of freewheel removing tools, and I work close to Bikeworks, which I have seen you say is close to you. If I have the right remover I can bring it to work and I'd let you borrow it.

Also, it really helps to have a bench vise. Put the tool in the vice, set the wheel on top and use the full wheel for leverage to unspin the freewheel. It takes some juice, especially if the freewheel has been on for a long time!
