so I started taking out the lining of a bell helmet my grandpa gave me and it's a paiiin! it's seriously glued in there, my dad tried to get it out last night and said I needed a wide scraper and I couldn't find one at the shop this morning so I've just been goin all medieval on it with a screw driver. so.. I put it in the freezer thinking it might make it a little brittle. it worked for Mr. Freeze, so maybe it'll work for me!
edit: it totally worked! I left it in the freezer for a few hours and stabbed it with a screwdriver a few times and then it came out like buttta.
