Don't know really. I don’t have a lot of free time to study, I easily lose concentration and would be better suited in a classroom environment. I get these pipe dreams now and again (not just because I’m a gas engineer :laugh:).
A bit of toing and froing on this but for the time being have decided against learning electrics as I don’t feel I have the right mind set currently to do it. I might go back to learning woodwork, but who knows. Vicious cycle atm.
Depends on which way you want to adjust. Looks like a Haps Colonial flag hinge, search this and you may find what you're looking for. The cover may need to come off with a hammer and striking implement, eg screwdriver or it may be a fixed type
Have you searched "anatomy of a mortise lock" using images? I've just looked but several come up, but none similar to yours, as above, the make would be handy
Oddly enough before reading this post, I thought, hmm he usually responds to my posts, even if nobody else does. Hoping he is ok. We haven't heard from some in the CC either.
