I have a couple of older powered slitters for cutting aircraft aluminum
skin. They are variable speed, hand held units. AL skin is pretty
tough,
but the little I have cut goes like butter once you get it started. Got
the devices at an auction sale. Only used them a couple of times.



Hmmmm.... I'm a pilot, and know about five A&Ps... I'll ask if any of
them have one of those.
