Are there tools for cutting old fasteners (5/16" dia bronze) from the
inside of hulls? If so, please advise what I can use to cut flush to
the inside of the planking. I am adding new frames before hauling to
through fasten with new. My boat has a fiberglass skin and I do not
want to break the skin anymore than needed.

I have been using side cutting disks on a 4" grinder. It works...but
is slow and messy.

It would be great to find a shorter electric or pneumatic hand held to
do the cutting.

thanks for help

dremel tool with cut-off wheel = small hand held electric.
or if rivets, use drill to remove head and tap/pull out.

If what you're needing is to cut flush against the planking and throu the existing fasteners, I think that a Fein Multiimaster with a flush-cut blade will do the job easliy and well. It's a very high quality tool, with price to match.

A reciprocating saw (e.g., Sawzall) with a long blade. The blade will
bend to cut flush with the surface. Something like 10 to 14 teeth per
inch and 8 to 12 inches long.

Good luck,

I second Jim Conlin's suggestion of the use of a Fein Multimaster. He
is right, they are expensive but once you own a Multimaster you will
continually discover things it can do that no other tool can
accomplish. If you try to cut with a long blade in a sawzall you are
going to damage the surrounding material. On the Fein you will have
to install a metal cutting blade.
