Hey guys instead of ripping out those roll pins try coating a steel wire
with a diameter a little smaller than the inside diameter of the roll pin
with epoxy. Stick it in the roll pin and let it set up. Then pull it and
the roll pin out. If the roll pin is one inch long and the inner diameter
of the roll pin is .050 the force generated by a 3000 psi epoxy bond will

 be 480

pounds roughly. Bond area is .050 times 3.1416 times one inch long or .16
square inches... times the 3000 psi  shear strength of epoxy or 480

 pounds.

Clean the roll pin out with acetone before you try to bond to it.

Not my idea. I forgot who came up with it but it is a good one.

 I tried a few things

Paul, I just remembered how I used to pull the flush wooden plugs covering
the screw holes on woodwork. I used long wood screw going through the center
until it hit the screw head below. As I kept going the plug came out. You
may try with machine screw ( not tapered) that just fits tight inside the
roll pin tight. Lubricate and see after it bottoms out it may pull the pin
enough to grab with pliers?.

Hey that is a great idea. Might work if you can find a machine screw just
the right diameter. Perhaps a metric machine screw will fit if a U.S. won't.
