Using a Bridgeport Slotting Head as a nibbler ???
awemawson:
Phil, yes thanks I have one that sounds very similar !
Bridgeport had to be turned back into a mill today so I had to break down the trial set up. I'm coming round to the idea of a conventional nibbler arrangement set into some form of fixed table. I have several nibblers ranging from the air one mentioned, up to a monster that will cut through 6 mm mild steel and scares the wits out of me when I use it :bugeye: I may investigate mounting the big scary one in a table and see how I get on !
dawesy:
Wow a 6mm cut with a nibbler. Think I'd be cautious of that too.
awemawson:
It spits out 6 mm cubes of mild steel at a great rate of knots :bugeye: It's also pretty heavy to hold. I took a few pictures - it eats through 6 mm plate at an alarming rate !!!

Hi Andrew
I would use a hand held jigsaw with a metal cutting Blade. No fiddling around setting up just drill one hole to enter the blade and away you go.
Cheers David

David,
it's horse for courses I think. A jig saw is fine BUT the edge is always a bit nasty and needs filing to size, AND in a soft metal like aluminium the face inevitably gets scarred. For thicker steel - 3 mm plus - a jig saw is probably what I'd reach for - being harder it doesn't scar from the saw vibrating. For open cuts I have a very nice Gabro notcher that cuts cleanly and doesn't distort either side of the cut, but it cannot be used for internal openings. They do do a punch press that would be nice, but they take up a lot of real estate and fetch silly money.
