Mains connection parts?

These work very well and are easy to install. They are also available in black or white plastic and several different sizes.

damn those are cool, I've seen the plastic ones, but a metal one would be very slick.

Someone gave me crap for spending my money on an rectangle panel punch; however, I don't think they understand how many amps I've built before I purchased that IEC punch.

I don't regret the purchase at all but very expensive.

Before that I used dremel with small disk cutter; or drilled large holes with a nibbler to enlarge then file to smooth; or multiple small holes, use pliers to pull parts off, then file; or drilled several holes to cut out with sabre saw. All of those methods suck.

I also get lazy or for a reason or two have to use a round hole with screw together power cord restraint.

For Fender amps I have a $7.95/free shipping from China restraint pliers that works great.

If you only build one amp or several just use whatever method you can, I understand you don't want to invest in so many tools but I use them in snowmobile repairs, mini bikes, motorcycles, truck, car and my 32 Ford Roadster. Forgot the skid-steer.

a punch is totally the way to go, short of a mill or laser cutter. I wish I had pulled the trigger when rs-online.com sold one for pretty short money. While I love my greenlee punches and ratcheting crimper I have, a single rectangle punches go over $350 when I've priced them out. Unfortunately I haven't been able just justify allocating that kind of cash for a single punch.... yet

Gland w/ nut. Sounds like you would want to get tested after using.
Seriously those look really cool. Dang something else I didn't know I needed.
