OK, so they aren't all that big, after all... For 1 hp I'd agree
it's pretty-much a wash. Only the little light duty shaper and the old
10" bandsaw are, here, so more incentive.

The example w/ the shaper is why I don't let anything past the gateway
-- if that were quick and you didn't react in time, there's not a much
more dangerous tool in the shop than a shaper.

I was fortunate in "glomming on" to a supply of the old Rockwell
starters used in a large woodworking manufacturing facility in PA (they
had 27 of the old Rockwell/Delta Model 13 planers arranged in 9 rows of
three set a fixed thicknesses the did rough prep on all the flat stock
coming into the plant. When they upgraded, they sold the lot either
intact or piecemeal for some of the more badly worn out ones.
Consequently I had a ready supply to retrofit with).

When I said "large tools" I was talking relative to small electric hand
tools like drills, grinders, circular saws etc. Actually after I said
it, I thought of changing "Large" to "Stationary" Point mainly was
simply you can put a lot of stuff on one 20 amp circuit if you only run
one tool at a time. Most of my motors are small enough I could run two
at a time, like DC and jointer. Third one, like air compressor would
often blow a fuse. I up graded to 200 amp service, so I'd have enough
room for separate circuits for stuff that runs in conjunction with other
tools, like DC. I have TS, Jointer, Lathe, Scroll saw, Drill Press, BS,
Shaper, Belt/Disk sander router table and Mortiser, plus most of my hand
tool outlets on one circuit.

The example w/ the shaper is why I don't let anything past the gateway
-- if that were quick and you didn't react in time, there's not a much
more dangerous tool in the shop than a shaper.

I agree there. In this case, When I flipped the power back on I was no
where near the shaper. For sure my heart skipped a couple beats when it
happened:-) Still, it was my fault for assuming the switch was a mag
switch. I had no experience with mag switches or even any switches
other than the standard light switch before that, so wasn't familiar
with their look. I stupidly thought all those big red/green button
switches were mag switches. I recall deliberately NOT turning off the
tool (with a grin) because I "thought" it was a mag switch.

starters used in a large woodworking manufacturing facility in PA (they

Naturally, I'm going to do quite a few at 54" and 16", but it's the
ones up
high I'm wondering about.

I think its a great idea. Not so much your specific application, but
the of putting outlets where you need them. It saves time, and creates
a safer work environment. Only you know if your application will do that.
