It's easy to handle and cleans up a chassis hole quickly, especially in aluminum.

And you guys across the pond seem to be able to get those "boots" that cover and insulate the back side of the IEC. Does anyone know of a supplier in the US. I have searched but had no luck, as yet
You do not have the required permissions to view the files attached to this post.
Yes, but once you see how much they cost, you'll know why most use other methods.
I like the old school cable hardwired. Molded plugs and no solid connection,along with most of the IEC using smaller ga wire just don't seem like a good idea. Mark Huss might have a Hiwatt story about cable differences.
I mill them on my Grizzly minimill. It works great and takes about 4 or 5 minutes of setup and machining time. (now that I have all the jigs for holding chassis) That's how I do the laydown PTs, rocker switch cutouts, and any other cuts that aren't just round holes. Those I usually just do with unibits on the drill press.
I use what paulster posted...the one with the built-in fuse holder (with spare fuse holder). Here is mine on a Ceriatone chassis...I squeezed it in the corner and used the 'other' fuse holder for the HT fuse. I used hand files.

Seek immediate medical attention if you suddenly go either deaf or blind.
If you put the Federal Government in charge of the Sahara Desert, in five years time there would be a shortage of sand.
I haven't seen an answer as to where to find a chassis punch for these things... If anybody has an idea I'd sure like to hear it. I love the final product but hand cutting these things is a royal pain.

I think a Harbour Fright mill drill is cheaper.

Greenlee makes a punch and Grainger sells them. I think I paid $279 some years ago. It's probably more now but when the choice is between using the proper tool or messing around for an hour or so with files and drills I'll spend the money on the right tool. For what a bare chassis costs these days you should get the hole punched for you thrown in on the deal.
$279??? For a few hundred more you can buy a mini milling machine and not be limited to making one kind of hole. You'll be able to do almost any kind of milling and drilling you'll need for a countless number of things. I'm just talking cost effectiveness here, the milling machine will be far more useful for so many more things, it's no comparison. When you can mill you can make any kind of opening you want to use, handy for rocker switches, laydown tranny holes, and a million and a half other things not just for amps but fabricating anything you want!
