Arm / Base - Rollpin removal

I'm restoring a 1953 Greenie and I would like to remove the Arm Base. The shaft that holds the Arm Base to the Base is held in place with what looks like a 1/8" rollpin which is driven into blind hold. Any tricks to removing the rollpin. The rollpin appears to be hardened and is difficult to drill out.

The roll pin can be driven straight into the base and will fall down inside the base. I find that you need a pin punch the size of the roll pin. Make sure the punch being used is flat on the end so you do not expand the roll pin as it is being driven out. The roll pin is case harden steel and normally cannot be drilled using regular steel bits.

Thanks for the quick response. I've driven the pin out and removed the shaft.
