There's
Old Woodworking Machines for some information. Not reviews per se. Many of the companies listed also made metalworking equipment.
I have older equipment from the following companies:
Delta - 1940s drill press
Duro - 1930s belt sander
Rockwell - 1960s tablesaw, bandsaw
Southbend - lathe
Walker-Turner - drill press
My father has:
Bridgeport - vertical mill
Cincinnati - pedestal grinder
Clausing - drill press, lathe
Do-All - vertical bandsaw
Kalamazoo - horizontal band saw
Advantages:
- Stuff can be had for cheap at auction if you're willing to put some effort into cleaning and refurbishing the machine.
- Heavy/Durable. Designers didn't have a computer to tell them that was really all the metal they needed to put into the machine to prevent it from breaking when it would inevitably be used in a manner not intended.
- Availability. A modern day equivalent may not exist, so it can't be bought even if the ridiculous amount of money it would likely cost isn't a problem.
- Little/no plastic.
- Duty cycle? What's that?
Drawbacks that come to mind:
- Finding original equipment in good shape without a lot of wear is a challenge.
- Finding parts ranges from hard to impossible as manufacturers have gone out of business, merged, been bought and product lines changed.
- Significant guarding retrofits may be required if OSHA compliance needed.
- Significant effort may be needed to get machine operational.
- True condition of machine not always evident until it is sitting in your shop and money parted with.
- Feature set and ease of use of newer machines often superior.
- Metric? What's that?
- Heavy.
