First of all, congrats on the nice work and result!
Q:
Is it possible to press the alu hub out of the cro-mo crank arms to have the inside cleaned and coated, and the outside painted? Then use Loctite 455 o.e. and press fit it back in. Reason for asking is that I want to restore mine but have the center alu insert original un-painted, and off course a better access to the inside..
Anyone done anythng like this? Is there a slight chance that the straightnss will be screwed?
I also would like to see more x-rays!
Cheers.
