Enjoying my 37 Colson Commander
First the expander bolt snapped off the neck, I did all the necessary steps to try and release the expander in fork after and before. I have soaked, heavy hammer with a longer expander bolt, would not budge, so then I cut stem because it would not budge so I could a better handle on the top head set nut, that would not budge. So cut it off. The lower head set flat part is just as stubborn, will not budge. Ive cut part of the top flat head set enough to get a wrench on it, nothing. Been working on it for 3-4 months now. Next step now is the cut off the fork just above and the top head tube frame bearing cup which will sacrifice the whole top of the fork. This is not my first rodeo, seriously this is a total bastard. Already past the point of no return, fork steer tube is damaged now. Even when fork finally comes out, I will need to cut most of the steer tube off and weld another from a donor fork if I want to keep the matching patina. At this point just want to save the frame. Head set, stem, expander bolt, all of it is frozen. And started because I wanted to grease the head set bearings and one problem after another.@fatbike what's exactly going on with your bike not wanting to come apart? What methods have you tried with the fork?
It looks like there's not much holding it together but I maxed the enlargement limit here trying to see
Usually PB Blaster frees up stuff; unless it has been over torqued or cross threaded severely
used it, pb blast, liquid wrench. Probably cross threaded, maybe slightly bent and keeping anything from moving. Several issues with it. Ha!
Excuse me I know this has taken over the original post.
