Arm / Base - Rollpin removal

[bucksaw]

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.

Dave H , I was able to successfully remove the roll pin from the pivot arm rod of my 1955 greenie without any problems. In fact at the time I did my first restoration I did not have the proper size punch so I used a finish nail as a substitute by clipping the point off and using the head as the drive punch. If you have the correct punch it should be easy. You can only drive the pin in one direction as there is not enough room to drive it from the inside of the pivot arm out. That part will be obvious when looking at it. Try squirting some penitrating oil in the pin whole to help things along. Just make sure you do not peen the end of the role pin over since you can only drive the pin one way. If you have the correct pin punch it should help prevent peening over the end. Just take your time and you should be fine. Good Luck----Dave

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