I have worked with metal of one form or another all my life and I have an interest in any and all ways of working with it.
As well as being a keen machinist, I also dabble in blacksmithing.
The thought crossed my mind today as I was staring at the plans for a 1936 popular mechanics midget engine, I wonder if there is a benefit in forging the crank shaft blanks.
At least at model size it wouldn't be too taxing. I could forge it from, say, 5160, and normalise it a few times after forging and before machining.
It could potentially be hardened after machining and then ground/lapped to final dimension.
Someone on here must have tried this before?
