Trying to remove core plugs from my block, i don't know the age of the block but i'm guessing 20 years.
The core plugs are propely stuck in. Old sealeant and rust. I've drilled a 6mm hole in each one, hoping to just be able to flick them out with a screwdriver or something. Yeah, that worked NOT!
I elongated the holes in one of the plugs, enough to get a pry bar in there, and then a heel par. Neither of which even make the plug budge at all.
I've now retired to the house for a brew, after soaking all the plugs in plus gas. Anyone have any ideas? I know Ffoeg must have some sort of clue
