Chassis nibbling

[Dynaflow]

 I have a 16x8x2 Steel hammond chassis I'm thinking about using in a 36watt lite IIb build I'm considering. I have the chassis already. Has anyone used a hand sheet metal nibbler on one of these chassis's. I'd need to nibble a power socket (iec) but the big concern is a laydown weber pt I have to cut a hole for. I could use a jigsaw if I need to, but was curious if a nibbler would do the job or is the chassis to thick to cut with a hand nibbler? They apparently are .04" thick. Anyone have experience with cutting them with a nibbler?

Regards and thanks,

Dyna

My little nibbler works fine on those thin Hammond aluminum chassis. I don't think it would do a good job on the steel though. And I'd hate to nibble a hole for a PT in any material. I recommend the jig saw. Cover the chassis with 2" masking tape so it wont get scratched. Mark on the tape, drill corners and one bigger starter hole, then go to it.

I use the nibbler on the Hammond Steel chassis all the time. I only use the steel ones.
I wear a nice thick leather work glove and nibble away.  I've done many IEC connector hole sand a few laydown PT type holes.

 Cool! Thanks for the info, I'll probably give it a shot.

Weber sells stand-up endbell replacements for most , if not all of his power transformers.

It seems to me the best option to get the big hole (aside from having a machinist do it, of course) would be to rough it in with the jig saw, and clean up the edges with the nibbler.  At the very least, that would be faster than doing it all with the nibbler. 

Of course, you could also just drill a line of holes, and nibble away between them.  But that's probably what you had in mind.
