Think auto body repair. Where smooth faced dollies, spoons and a hammer are used to reshape dented metal. Place dolly on inside and tap tap tap to reshape. Just light taps at a time. Same technique could be used for bent areas. You will have to make the dolly or dollies. Super smooth as possible. Go slow.

For example I had an aluminum cylinder with a piston that had O’rings seals. The cylinder was dented during O’ring replacement. I used a pipe just smaller than the cylinder. Cleaned, smoothed and polished as best I could. Then with a rubber dead blow hammer I worked the dent out. May have used a regular hammer too. Can’t remember. Once done the cylinder worked again and leak free.

Good luck with your repair.

Just remembered that Harbor Freight sells a watch makers hammer that may be good for this repair. Check it out. Then you just need the dolly.

SKU 99895

I like that item,.. I'd use a nice piece of hardwood for the dolly, Aluminum is quite soft and wood will help with not scratching the surface so much
