removing stubs inside cowls w/o using dremel tools?

like a foolish baboon that I am, I superglued the halves of my cowl together and then discovered 6 large locating tabs on the walls… they are paired up back to back, and there are three pairs, so it wont be as hard as removing six different ones, but still, how do I get to those?

I don’t have a dremel tool on hand. rather, I do, but my charger got thrown away… (so close, yet so far…) do you guys think ACE hardwear sells chargers? its the transparent blue model that I’m talking about, and if they do, how much do you think they cost?

I’m thinking about using a hot screwdriver or knife, but the radiating heat might warp the cowl itself.

thanks for the help [:D]

Are we talking plastic or resin kit? Could you CA glue some sandpaper around a dowel? May have better luck finding a universal charger at Radio Shack or similar.
