I have another stupid question! I cannot remove two roll pins (also called spring pins) from a casting.
The casting weighs about 250 lbs (cast iron), and the roll pins protrude about 1-3/8" from the side. They are 3/8" in diameter and about 2-1/2" long - too hefty for a wimp like me to remove, apparently! I have tried a vise and visegrips to compress them without luck. Don't think heat/cold will work. My old auto body puller will not grip them tight enough. Cannot get at them from the back - in blind holes.
Can they be drilled out? Is there a better way? They need to come out so I can remove bolts to a sub-assembly. They are super hard and in there tight!
Thank you all for your responses. I have learned a LOT from this great source! A.T.
