As tools go, the Adel sheet metal nibbler is an old standby, but new to me. For those of you already familiar with the Adel nibbler, there's probably nothing I can add.
However to those who are NOT aware of this handy little device, this is, I believe, a must have.
I'd spent some considerable time searching brick and mortar hardware stores for the Adel nibbler but to no avail- despite it being a longtime sheet metal tool standby. Ordinarily, I don't shop the internet. But in the case of the Adel, it was most easily acquired this way.

This one was purchased from an outfit named 'Aircraft Spruce & Specialty Company'. Now that is fascinating of itself. The seller supplies spruce wood for airplanes, something I'd never have dreamed is still in practice.
Aircraft Spruce has two locations, one in Georgia and one in nearby Corona California. (nearby to my home in Desert Hot Springs, California) I ordered it Monday and by Tuesday it was at my door.

In this pic you can see how it compares with a less expensive Taiwan import. I'd found the import near impossible for cutting 1/32" thick brass, while I'd found the Adel gets the job done with ease. Part of this is due to the fact that the Adel cuts off a smaller chunk, so that more force is applied to a smaller area- in other words, it bites harder, enabling cutting of thicker material. You'll also notice the difference in configuration, which actually the import is easier to read its direction. However, that's pretty meaningless if you cannot cut the thickness of material you are using.
The Adel is old school, designed to be able to replace its bit when it wears down- and it's made in the U.S.A.
This is much easier than using the Dremel, as brass gets quite hot under a cutoff disk. Not only that, but Dremel wheels like to travel, having ruined many a nice piece of brass.
Hope this helps, chassis builders-
ThanX,
