Here is a modification I made to the lens hood of the Pentax 60-250 so the little filter door cannot be lost. (it is just so small and so easy to lose)
1) Take something sharp and pointy to mark the spot where you will drill (Otherwise when you start to drill the drill bit will wander all over the place and ruin the hood)
2) Take a 1mm drill bit, (not bigger) and drill holes where you have marked. if the drill bit is too small for you drill chuck, wrap a bit of masking tape around it, it will grip the bit enough for this job if you go slowly.
3) Take a length of this woven Nylon cord, (find a little halyard from old something) tie a knot in one end, cut end off and seal with flame so it won't fray.
4) Pull cord through the hole from inside the hood, thread it through the other hole of the door, (5) measure a suitable length and do another knot, cut off past the knot and seal with flame as above.
6) prepare a small amount of 5min. Araldite and dab a small amount on the knot inside the hood. (I said small amount didn't I) Wriggle the cord a little bit to make a small amount of Araldite to come through the hole on the other side. (See picture 7). Now let the door dangle until the Araldite has cured. After this repeat the process with the door and let the hood dangle.
When the Araldite is fully cured you can dab a bit of matte black paint on the little blob of Araldite, and the job is done.
