I’m going to go out on a limb here and guess that they don’t want the workman’s comp or insurance hassles involved.
The two machines most likely to produce injuries in a shop are:
1. Drill press.
2. Bandsaws.
There’s no way to put guards, interlocks, etc on these machines and have them do any useful work. They’re very useful machines, but they’re unforgiving of idiots.
And we’re hip-deep in idiots these days.... idiots who have their attorney on speed-dial.
Nope. Simply too cheap to spend the money.
