This will do it with patience and calm, sure, attitude. Purchase a good 120vac powered Dremel tool Pawn shop is OK if it works and has a good 1/8th inch chuck/collet. Purchase 1/8th inch shanked diamond tool for the Dremel. It should be at 1/8th, or 3/32" diameter, and shaped like a small cylinder, or pointed with the widest part no bigger than an eighth inch. This will grind the tap very successfully. Start in one of the flutes (gaps in the hard part), and grind away the center of the tap from outside to inside, Stay away from the engine casting, and do not hurry at all. once the center is ground out to the depth of the diamond, go deeper until the center is actually gone. This can take 2 hours, and several rests to avoid hurrying. The pieces will fall out (or can be picked out with a dental pic) when the center is gone. The EDM machine is a great tool, but requires the block to be submerged in dielectric fluid, and laying on its side. Best of luck, and your mistake included the a bit off center, and not going forward no more than an eighth turn and back a quarter turn to clear chips. Learning by snapping off a tap is a great method of avoiding it in the future. All is well! JimN
