Just realised my points are ground/sanded/abraded at an angle.
As I rotate the adjustable side it's like rotating two wedges against each other.
Combine the original wedginess with people[yep me included] dragging
the side of a matchbox though the points and they are really ropey.
No wonder gapping them is such an adventure.
No it hadn't crossed my mind to take them off and have a look at them.
After looking at them I decided to lap one face true to the thread axis. And
finish the other contact so it contacts sort of centraly.
Lucas mag so it's going to be BA, I eyecrometered the adjustable contact at 5BA.
I threaded some scrap 5BA to hold it, nope it's not BA, it's M3.5!
The rest of the threads on the points are metric, the spring retaining screw was
clearly metric, no prizes for guessing which one it is in the pic.
I haven't taken the oiler screw out, yet.
So these must be Indian points and they use whatever threads and screws they have at hand.
I am going to have to get/make a proper points block if I get a set of lucas points.
Or maybe silver solder new bit's of tungsten on, I gather green is the one for points.
The pic really doesn't do the threaded contact justice, it's lovely and flat.
