   Charlie- I realize that you already got the rods off, but I thought I would chime in with my
method for getting rods off without using hammers. I like to loosen both nuts on the cap,
then finger tighten the nuts so that both are just short of bottoming out on the cap, then
rotate the crankshaft slightly so as to "push" off the cap. Then finger loosen the nuts another
couple of turns and rotate the crank again, repeat the process untill the cap is off. As long as
the cap remains level, it wont bind on the bolts, and the cap will usually come off smoothly.
if the cap starts to rock (tip to one side), simply tighten the nut on the high side slightly, re-leveling
the cap. No, it is not the fast method, but it does work well and will not ding, damage or score
anything, and doesnt require buying any more tools.
 
As far as the nick problem goes, no, it is not fatal, and yes 2000 grit sandpaper will work. I would
not recommend you try and use a file on it, as it would be very easy to over do it. You may find
that 600 grit with wd-40 would work better, but trying the 2000 grit first is the much safer approach.
