Deformed Headtube Around Bottom Cup Crashed into a fallen tree at speed on my bike. I disassembled the front end to inspect for damage and noticed I could wiggle the bottom headset cup back and forth slightly. On further inspection, the bottom of the headtube is slightly deformed as can be seen in the below pictures:





There are no cracks or other damage visible, but the bottom cup no longer fits firmly in the frame. 

Does anyone have experience fixing something like this on an aluminum frame (not too expensively) or is the frame/bike ruined? I know aluminum loses its strength as it's bent.

Searching online I was able to find references to epoxying the bottom cup in place and using strips of aluminum to pad the gap, but that doesn't sound like a particularly safe fix.
If I was that desperate to save the frame, then the epoxy method sounds quite reasonable.

The only difference I'd make would be to use some carbon fibre in place of the aluminum strips. It's pretty cheap to get a short roll from Aliexpress

Put the bearing in and out a couple of times until it's a snug fit. Pull it out, epoxy the carbon, pop it back into place, clean excess resin off 

If you can do it with the bearing wrapped in glad wrap, you may not even have to make it your last ever bearing change as you should be able to remove it once the epoxy is set

Whilst the aluminium will have lost some strength, it's not going to fail catastrophically in that position as it's really well braced
