They have a unique polygon design, that you can't readily find a driver for (except at McMaster). If you have some serious bucks, I understand that you can privately license they key for a particular polygon.

Not looking for anything as elaborate as the private license keys but good to know they exist "just in case". The enclosure is basically to help deter a smash and grab.

Those are great screw heads. Not sure if I want to use those types of security screws or the kind that only drive in one direction. I guess the security heads would at least give me a better option if I ever need to remove the enclosure.

I will need to put some type of tab w/ hole arrangement for a padlock so I'll find out then whether I have the same problem you did with the bracket. I'd love to TIG this project but I've never even tried to TIG yet. Have you used the TIG function on your Power Pro 256?
