Definitely possible. Not sure I would try that with my cordless drill, though.
I would have used this for the drill :
but C- clamps work well, as you've demonstrated.
Also, my understanding is that you quench red/white hot steel in oil to harden. It adds carbon to the surface. When you heat again, fold, pound over and repeat - this process increases carbon, therefore hardness. Not sure what water does. . .
I made a 3.5 inch scalloped wood chisel in college. I used oil to quench and followed the process I detailed above. Worked great. Even had that bluish tone/ patina.
