[C320-list] Press Stud for Cockpit Cushions

[Pat Ireland]

A quick search brought up a forum recomendation to try slotting the
remainder of the screw with a dremel wheel and using a small flat blade
screw driver to remove the screw.  The wheel will cut into the glass on
either side of the screw, but unless you can back it out with a left handed
drill, you are in for some repair anyway.  That same thread suggested that
if you attempt to drill it out, use a short piece of brass tube from a hobby
shop as a drill guide to get a drill center point started.  And then there
is the thought that acetone might help loosen up the screw.  Disclaimer -
never tried this in fibreglass.  In metal we would remove the material
around the screw with a modified center drill (point slotted out for a
pocket to clear the screw material, leaving the countersink cutting edge to
remove the surounding material.  Then the hole gets filled and redrilled.
It's the fall back approach when you can't drill out a tap or drill because
they are made from very hard material.  But it is also very difficult to do
with a hand drill.  In fibreglass, routing around the screw with a small
dremel bit is likely easier.  Good luck on your effort.  Pat, 801
