If you inadvertently let some epoxy get into a hole and then forgot to take
the bolt or screw out, chances are, the bolt is in there for good. Even an easy
out will battle to remove the bolt.
SO, by this stage, you have already stripped the bolt head and cannot drill it
out because then you will drill into your T-nut which is already in your
beautifully sealed hull......
Here is a little tip for getting a bolt out . Epoxy starts getting soft at
about 120- 130F, so much so that there is a large debate going on in the
homebuilding aircraft market about using epoxy on wings, then painting the
aircraft black. Some manufacturers are suggesting that they paint all aircraft
a light colour if they live in a hot zone of the world. The results of a black
aircraft sitting in the tropical sun and then taking off with gooey wings could
be ... interesting.
Anyway, back to getting the bolt out. Take a very small size DULL drill bit and
drill into the centre of the bolt. This will heat the bolt up to such an extent
that the epoxy will soften enough to remove the bolt with a pair of pliers.
happy building
