Steel fork, alloy quill stem – I’m trying to remove the stem. The bolt was pretty easy to loosen and the wedge is also loose. I guess that, because of getting wet many times – about five years since it’s been removed -- the stem is frozen onto the steerer tube (on the steel fork.) It won’t move at all. I’ve tried spraying some Liquid Wrench (penetrating oil) into both ends – still no movement.
My next strategy is to build a vice out of a couple pieces of 2x4 to hold the fork. Then I could apply more force to the handle bars – the limitation now is that I don’t have a good way to hold onto the fork. Is this a bad idea?
The stem is a Cinelli (somewhat vintage) that I’d really like to avoid damaging. The fork is more expendable – if it comes to that. I also don’t want to damage the frame.
