If the coil has an Allen key style slug in it you then you keep the board mounted and you get a special plastic diddle stick that has the Allen key on the on the end and a skinnier round shaft above....you push the tool into the top slug then keep going down till it disengages with the top and then you feed it into the bottom slug....these were common in the 50s and 60s and I find them in service caddies periodically...

Some coils use a flathead screwdriver style adjustment and some use an Allen key adjustment... whichever you have ALWAYS only use plastic adjustment tools. Metal alignment tools will crack the slugs and also change the tuning so if you tune a coil with a metal tool the instant you remove the tool the tuning will shift.

Also unless you have a working sweep/marker generator and a scope DON'T touch the video alignment it is close to impossible to get it right by eye.
