It will help to have someone hold the bike upright. I would take my time and use a dozen or so calibrated blows to get the tube straightened but not "over-straightened". It should come out almost perfect in my experience. Do not hit the tube with anything harder than wood, or you'll flatten/collapse it.
Does this method work better than just standing over the tube?
I tried splitting a drilled block and standing over the seatstay with my full weight and heel, and it did not budge at all.
I bent my rear triangle 2 years ago when chain got between casette and spokes, because I was a n00b. Well today I made new wheels because of bearing problems and 13-24 old uniglide 6 speed casette.
I made a straight wheel and realized it won't sit straight. I started looking at my rear triangle and at least 4 things are ****ed up:
- right seatstay is quite a bit bent towards bottom bracket
- right seatstay is slightly bent towards left seatstay
- left seatstay is slightly bent towards bottom bracket
- left seatstay is slightly bent towards left
This is the worst in right seatstay, bent towards BB:
Right bent towards left a bit:
Left bent towards left:
Left bent towards BB:
Park tool SS-1 is the tool but no one seems to have it anymore in Finland:

Would FFS-2 work?
