As you would expect, there is a heavy emphasis on safety.

They have a collection of table saws including General, Delta Unisaw
and PM66.

Over the years there have been a few T/S accidents.

Analyzing these accidents revealed the following:

1) The majority of accidents involved the PM66.

2) After shutting off, the PM66 required 20-30 seconds more to come to
a rest than either the General or Unisaw.

Looking at the saw blade, it was very difficult to see if the blade
was still spinning.

The only time I've ever come close to getting bitten by my Unisaw was exactly
this. A blade brake would be a great addition to any table saw.

You had to literally "feel" the blade still turning by touching the
table.

Those of you who have a PM66 are aware of this phenomena; however, if
you buy a PM66, be aware.

A PM66 is NOT the same as the General or the Unisaw.

BTW: These saws were all equipped with Biesemeyer fences.

Strong like bull, but give me a Unifence anyday.

Never used a Unifence, so can't say whether I'd like it better or not.
Why?
