I need advice on a situation I am having with an old Bianchi road bike I received from a friend's relative. The bike itself is in fairly good condition. I'm doing a complete overhaul seeing as most of the parts are rusted, weathered, or in a condition that is unfit to ride. I've made great progress stripping the bike all the way to its frame until I hit a snag. I was trying to remove the "stem", I believe that's what's it's called, you know, the part that connects the handle bars to the "fork", and on my bike it's all held together with a long "hex" screw. Well, it seems that it's either really tight or just really rusted because I can't get it to move an inch. I've looked up various solutions, but none have worked for me. I'm getting so frustrated because this is the only thing keeping me from proceeding with fixing this bike up. Any suggestions would be appreciated.
