Must cut 40mm hole in 1/4" aluminum bar

It was too many of those at the office that convinced me there would be no HP printers here in MY office. Got a brother all-in one at my wife's desk, and a Canon inkjet and Lexmark color laser at mine. I've got a Samsung monochrome laser and an old HP Laserjet sitting on the sidelines. (I bought the Canon new - all the rest are "salvage")

No, I buy defective test equipment and restore it. I've done that for over 50 years. I started in my mid teens when I couldn't afford new test equipment. TV shops had a phobia about repairing their own equipment so they would pile it up in the back of the shop. They would sell it cheap, or give it away. I repaired as much as I could and used the other for parts.

Now that I'm retired, it is how I spend my time. It has gone from a hobby, to a career, and back to a hobby. It's a better hobby than trolling Usenet.

I have a pile of old printers, left from repairing and giving away used computers. Most work, but not on later versions of Windows. The do work with Linux, so they will slowly go away. Bad laser printers are scrapped for the motors, rods and some ICs. Most HP printers are scrapped for hardware when I get them.

I don't even bother taking injets apart any more - or late-model HP lasers. If this HP didn't have a full cartridge and a brand new spare with it I'd have scrapped it. It was the only "orphan" in a customer's office and they were standardizing on printers that all used the same supplies so they put this one in the discard pile they paid me to dispose of. Along with the Lexmark color laser with one spare toner cartridge.

Really? All Wieber does is troll Usenet, and it seems that's all your "contribution" [sic] here is.
