Flame straightening a shaft

[Pete O]

Sounds very feasible that the shaft is too thin for the technique to work, is probably getting hot enough right through the shaft to defeat the purpose. I have only ever done it before on larger shafts without the same precision required.
Unfortunately I don't own a press nor have access to one, it is on the project list, perhaps it needs to climb a few rungs on said list. I've actually used my petrol-powered hydraulic log splitter to press a few bearings but no way would that do this job.
