44: Apin visewith a #76 bit is used to open holes that
have been filledwith paint by themanufacturer.. Keep
the drill perpendicular to thework, and apply light
pressure as you drill. You can expect tobreak some
bits regardless of how carefully youuse them. I stock
upwith extras so I won’t be looking for a bit to finish a
model onSundaywhen the local hobby shop is closed.
Drilling techniques
Manyyears ago, oneofmymodelingbuddiespointedout,
“nobody likes todrill out holes for grabirons.”Unfortunately
this activityoften comeswith the territory. If parts suchas gra-
bironsor ladderswon’t easilygo into thetinyholes, then the
holeswill have tobedrilledoutwith thepinvise.
Expect todo this, andyouwill bepleasantly surprisedwhenyou
don’t have todo it.Whenusing thepinvise, trynot topush too
hard, andkeep thebit perpendicular to thepart beingdrilled.
It isnormal tobreak thebits, sobuy them inquantity. I always
drill byhand. Thepreliminary
