OK dude lets tackle the biggest problem...you said you nicked the cord on the dremel and soon after it quit???is that right??? ok you gotta have a dremel to build a boat..so lets fix it safe to say the wires was cut enough that it lasted a bit and then let loose. sooo use a sharp knife and cut through the black insulation on the cord MAKE SURE ITS UNPLUGGED..cut an inch above the nick and an inch behind it. carefull not to nick the wires when doing this..remove the black insulation then you can see the wire that got cut..strip a half an inch off each piece and twist the metal wire back together tightly..wrap that with black electrical tape and then wrap the entire area with electrical tape..then plug it in and I bet it runs fine....

Now take the repaired dremel and put in the cutting wheel and cut a slot into the head of the 2 screws on the plate cut as deep as you can if you nick that plate its ok it gets disposed of....now do like Dicko said and put it between your legs put the slot screwdriver into the cut you made and smack it good with a hammer then turn the screw out it should come right out the heat from the dremel work will loosen up the loctight real well.....
those extra bolts are to fasten the new motor mount on with... the flat heads will replace the screws you stripped....

Ok NEXT??????
