Minor update. I have begun making my 3d model and I have researched more about aluminum to wood bonding, and I agree that there seems to be some cause for concern. There seems to be a lot of ways to make aluminum bond well for a few years, but then bonds have a tendency to fail.
The main issue I have right now is that I can not find a headtube that does not need to be reamed and faced. I do not own a headtube reamer and prices online were around 400 for one so I have no plans for buying one. Since my headtube will not be welded I do not have to worry about distortion.
Does anyone have a source for pre-reamed headtubes?
