I friend of mine is bringing over his boat so we can drill 1 1/8inch holes
in his boat for pole holders.

This is a boring ol' fiberglass boat, but I figured I'd post a question to
you experts for some suggestions to make sure it goes well.

Could you give us any suggestions/warnings/hints about drilling into
fiberglass to make sure it goes well.

Any help would be greatly appreciated.

Thank you, from a novice boat builder

I'd say the most important part is to cover up well so the dust doesn't get
all over you and make you itch for several days!

Use a hole saw.

A couple of things to worry about (we'll think of more):
Look carefull at what you might drill into- wiring, piping, a tank, finish
work, etc. It's easier to pull a wire harness aside than to re-splice it.

Determine if the deck is cored. If it's over 1/4" thick, it is, and you
need to seal the core. Depending on what the core material is, techniques
vary.

No question is so simple it can not be made complicated. Pole holder? are
they gunnel mount rod holders? 1 1/8" sounds too small. Perhaps you are
talking about some out rigger holders that are placed in the gunnel. I am
just guessing what "pole holders" are but if they are to be mounted in the
gunnels, usually you will find the "covering boards" (tops of gunnels) are
cored with wood maybe 3/4" plywood or 1/2" or something. Anyway, you will
need a hole saw 1 1/8" or whatever. Replace the 1/4" dia. pilot bit that
came in your hole saw arbor with a longer 1/4" bit, maybe 6" or longer. This
is so you can guide the hole saw as it begins to cut as all the "pole
holders" are usually at 30 degree angle, so sawing the hole at this angle,
or there abouts, is part job. Without the extra long pilot you will have
great difficulty. If these pole holders turn out to be outrigger holders you
will need to put metal backing plates on the underside too. Aluminum ,or
your corner's stop sign, is good for making the backing plates. I use
backing plates on hold holders as well but unless you are after some big
mean fish you can do without the backing plates.Oh, don't even think about
not thru bolting and nyloc nuts are good because they holders tend to loosen
up after they are knocked around a bit.
