Are the sharp things fiberglass
strands? Or are they bolts and fasteners holding stuff on deck
, a piece of sandpaper (say 50 grit...) on a block will do the job.
Do not pick up an angle grinder and expect any pretty results...
If they are bolts and nuts, you can either add stainless acorn nuts to the bottom (Take the nuts to the store and find the thread pitch
, or measure them, or get a thread pitch
gauge...) and put them on. Or you can take a hack saw or cut off wheel
on an angle grinder or dremel and cut them just above flush with the nut. File down flat...
P.S. It looks like a big project
, but you can click my signature to see what you are getting into. I suggest you hire a SAMS or NAMS certified surveyor
to come check her out, for a few hundred bucks... just so you know what you are getting into.
