Hi sortafast:
To the best of my understanding, both machines are obsolescent technology.
That means nobody who runs a commercial enterprise will pay you anything but "parts donor machine" value for these, even if they are still working.
Also, you need to find a shop that has these in operation and is able to buy and store a parts machine...they will be hard to find and will likely be cheap bastards (like me) looking for a super deal in order to keep a dog running because they're too cheap to buy modern.
Your other option is to find a hobbyist who wants to put a machine in his garage.
Good luck with that...if you thought cheapass companies were cheap...hobbyists are a thousand times worse and will often expect you to support their new toy too, even if you have zero understanding of how they work.
I'm guessing you could get maybe five grand for the pair if you parted them out yourself and were patient and persistent.
Carting away the two skeletons when you've taken all the useful meat away might cost you a grand or so if you're creative.
So best case you can net 4 grand with a year or more of effort, stripping the parts, storing them, and marketing them.
You may do better offering them to an EDM rebuilder.
EDM Network in Illinois reconditions machines and may have a modest interest in them.
Be sure to call them first before you commit, and find out if that's really true or if I'm just blowing smoke.
But yeah...unless I just happened to want something in my shop to burn out broken taps or wanted to start a small molding and moldmaking operation, or were a knifemaker looking to burn logos onto his knives, I'd steer clear of them...they're dogs...even if they were once fine, state-of-the-art machines.
Cheers
