Armor removal and armor screws

[Mrs Vampire]

Hi I am up to removing the armor from my Stuart.

I have done this before many years ago on on other Stuarts with less than happy outcomes for the armor screws.

I have so far done the full flush with oil of wintergreen etc mixtures to get as much penetration as possible. I have whacked them with a 1 inch drive rattle gun . My next trick will be to heat them and cool them try to get a bit of penetrant into then when they are warm .

Heating stuff up is always a trick with all the accumulated oil etc around.

I cant find any reference to special screwdrivers for armor in my parts/reference books. The screws are a pain as they have very narrow slots given their size. Every screw I stuff up means a screw I have to make.

Any clues would be gratefully received.
