Filling Old Wallplug Holes

The Hall effect?

But do Fein make wallplug-hole-filling machines?

Of course not. It's the gold plated filler knife you need.

A mid size pozi screw driver with the tip cut off (grinder) is about the same size as a yellow plug

Matchsticks a little shorter than the hole.

Do you remember those giant matches - for fire lighting, I think?

Well they wouldn't be thick enough! :-)

I ended up using Screwfix' finest (i.e. cheapest) gripfill-alike-non-solvent - squirted it into hole and kept slowly squeezing as I withdrew the nozzle. Left it at least overnight - then filled the remaining hole, largely caused by shrinkage, with ordinary filler. And all is well.

Any clues how to get over OCD and autism?

I can also give a very big recommendation to Polycel(?) "big gap filler" not that squirty foam stuff but the stuff that comes pre-mixed in a tub. It's very grey in colour but I sucessfully used it to re-create the missing 6" square area in the corner of a plaster/lath ceiling by using abit of polysterene as a backing (only flat substance I had to hand) then screwing some screws in for a bit more "grab" factor, finally using big-gap-filler to fill what was lath/plaster.

Tiny bit of sanding and a spot of paint and you'd never know it wasn't original.

Definately one for those otherwise impossible jobs. :¬)
