To align old National receivers you have to peak inductors by moving a "loop of wire inside the coil form" with a stick. What a pain, I made a tool to help me do it and it works really well. Super simple; get a plastic coffee stirrer and a paper clip. Open up paper clip, get the "edge" hot with a lighter, and then press the end of the coffee stirrer onto the hot edge of paper clip. Melts a nice 1 mm deep "slice" into end of coffee stirrer that nestles nicely into the coil, you can then push-or-pull coil and it stays put in end of coffee stirrer.

You might have already thought of this, but ...

There is a tool called a 'spudger'. It is supplied with some alignment tool kits. It has the notch for coil winding manipulation:

It is also handy as a non-conductive probe and flatblade.
