Cruisin' on my Bluebird
Acetone and ATF (automatic transmission fluid) is the best I've found for breaking up rust. A couple of times I've completely removed the wedge bolt and the stem then screwed the wedge bolt back into the wedge. Loosen up the head set bolts and take the fork out of the frame. Fill 'er up with the Acetone/ATF mix and let it sit for a while. Then using some rags to protect the finish, clamp the fork into a vice. Take a slide hammer and put the forked fitting on the slide hammer. Hook the forked fitting under the head of the stem bolt and use the slide hammer to start yanking on the stem bolt. Pretty soon it will pop loose. If you don't have a slide hammer , you can borrow one from your local auto jobber - Advance, Autozone, NAPA, O'Reillys. GO BIG!
