Current Projects chat and miscellany

Thanks. I have enquired with a local repair/modification/framebuilding place.

if you don't want to do the required research

Curious about this. I'm guessing this is the sort of thing you learn by spending years in a workshop with a framebuilder or in an engineering degree, but is there a book I can read or something? The internet tells me that framebuilding books are not very good and the internet is a better resource.

From basic materials stuff I understand that tube stiffness is proportional to tube diameter (along the direction of the force) hence if I crimp the stay they lose some lateral stiffness. But I just don't know enough about how important lateral chainstay stiffness is for a given frame. My own gut feeling is that a Kona Sutra uses cromo big-diameter tubes, is way overbuilt and is not crimped already, so given that other frames with smaller tubes have crimped stays, I'm fairly sure it can take it. But that's not very scientific.
