Hi All.
We all know those lightweight nibblers with the 1/4" square draw:
http://www.amazon.com/Hand-Sheet-Metal-Nibbler-Cutter/dp/B000T5FV4Q
For anything real, they suck. Seems like once the sheet is thick enough to not bend and jam the die clearance, it is too thick and you break something in the nibbler.
Does anyone make a larger one that can handle 1/8" aluminum or #16 ga steel with maybe a 1/2" square die? Face panels need rectangular rocker switches and digital meter cutouts, rectangular IEC connectors for power, many multi-pin connectors need rectangles, not round.
I'm thinking a 1/2" square die, cuts on two sides tapered so the corner starts first, like an eagle beak, and a bit of relief on each side to go deeper without having to get creative. Hard to describe. Need a 3/4" square hole? Drill 5/8" hole centered, simply take four yumps in each corner, and done, That much relief in the undercut of the die.
If I can't find one, I'm gonna make the damn thing. Use a pneumatic pop riveter for the oomph, they have a large threaded chuck mount that can be adapted, with at least a good 1/4 ton of pull. I bought one of these riviters, to put 200+ 1/4" steel pop rivets to mount e-track in a boxtruck. Not a job you want to do by hand.
Although I'd rather buy something already out there, any ideas?
