Well, I have aligned IF.
I made a tool. One more BiC ball pen lost its life, but it was not for naught!
First of, it is a well-known way of making makeshift nut drivers, molding heated plastic tube (semi-translucent ballpens are ideal, exactly the plastic that is hard enough, easily molded but does not crack) around the hex shape to be driven.
This time it was not the pen main trunk but the small cone that holds the cartridge tip itself.
I drilled a suitable hole in a piece of wood, to serve as a stable holder, and shaved the cone-shaped tip-holder to be a cylinder of about 5mm or so in diameter, to fit inside the well to reach the ferrite slug.
In went the cone, and I shaved it with my Exactlo knife into a cylinder.
Then I used the bottom slug to morf the heated cylinder into the nut-driver shape. The slug sticks out so it is ideal to form the hex shape. Earlier I formed another cone to serve as a driver for these, but it only is usable for these bottom cones, as they are readily accessible.
After the cylinder cooled off, and became solid, I took it off the slug
Then with my Exactto trimmed the edges that bulged up a bit, which would preclude the cylinder from going inside the well, and glued it into the ball pen.
Now I have a universal tool to drive the slugs that stick out or hide inside.
I checked the alignment of the BC: since the clear marks for the needle positions are not there, I was satisfy to see that about between the middle to the left end of a number the SG would make the radio beep.
The local station now is extremely loud, even at low volume, and there are many stations pulled by using that 4" (about 10cm or so) piece of wire
as an antenna.
There is mostly noise on LW and SW (I will have to see SW during the dark part of the day with some better antenna, outside the basement).
I hope today I will put the radio together to bring it with me to FL, to show to mom.

People who do not drink, do not smoke, do not eat red meat will one day feel really stupid lying there and dying from nothing.
