When I was in MD (Kitts) field work on one of the ASC units.  I fit my electric dremel with the router fiting.  First a round (ball type) grinder then a cylindrical (like Alan pictured)  YES lots-and lots and lots of filings.  I used 2 large magnets, one attached to the plate above the grinding and the other on the keybed below the grinding area in additinon to a vacumn.    Don't have to repeat take your time but, hey, I just did.  Slow & steady wins the battle.   Good luck!

An angle die grinder with various carbide burrs will work fine to hog off the majority of the material. I use burrs with several shapes – christmas tree, cylindrical and one I find particularly useful is one like this: <IMG src="cid:3394530517_6050391">  Then, still using the die grinder switch to a 2” sanding disc. Start with 36 grit, then move up in grits. That’ll get you a decently flat surface. I don’t think I’d use a Dremel for this work mostly because I just prefer using air tools. Wear a mask. The cast iron bits will go everywhere so cover everything up well, and because you are in a home (yikes!) you might use a vacuum as you work.
