[Hallicrafters] Knurl Nut Wrenches

[Paul Kraemer]

All this discussion prompts me to suggest what I had been thinking all 
along.
Find a suitable piece of pvc pipe, slightly undersized, heat it with heat 
gun or lamp and gently force it over the offending nut. Let cool and maybe 
you have a perfect filt wrench. Maybe not. At least it won't hurt anything 
and very little lost if it doesn't work. Much gained if it does.
Allen Bradley had this for some of their industrial control panel buttons, 
switches, lights.
