Cusser If me, I think I'd run a tap into the unthreaded end, clamp a Vise-Grips on the tap end, and hit the Vise-Grips with a hammer. Or let the machine shop handle this.
MazdaMitch Cusser This block is not going to the machine shop, its ruined. But I do want to figure out how to save these dowels.
Xoloanon If the block is trash could use a cut off wheel and cut the metal around the dowel. Might just fall out once you make one slice.
MazdaMitch Xoloanon I need to hole and threads intact so that I can put this on a engine stand. Maybe I will go ahead and to the engine stand stuff and then later chop it off and do as you described.
Axel-Breaker-Earl Heat the tip of a smaller (not smallest!) flat-head screwdriver up and "curl" the screwdriver tip to a 90° bend with a hammer.......you can then insert your new tool into the threaded end and butt the 90° end of the screwdriver against the backside of the dowel and tap it out by going around it evenly. You can use a mild steel (not hardened like a drift) dowel also, and heat and shape the end with a hammer the same way. You can also apply heat to the block if it is still being stubborn.
MazdaMitch Axel-Breaker-Earl I thought about that. I'll have a hard time picking a screwdriver to part with.
Axel-Breaker-Earl LOL......get a Harbor Freight doner! 😉 I've thought about buying a small slide hammer and making some oddball tips for it, for these type of jobs. I need to do it!
