I'm having trouble visioning the actual cause of the purported early
failures...
Only one I can think of offhand is cheap switch contacts, perhaps.
Other modes I can think of are basically proportional to run time.
The last 3 issues of Woodwork magazine have schematics and an article on
this subject. I built the units and am very happy with them.

The last time that I looked at one, the sensing circuits were a little more
complicated than that although most of the higher power ones did contain a
relay or contactor to carry the load. The down side was that you needed to
have a separate sensor on each circuit that had a power tool you wanted it
to respond to ($$$$) and the DC had to be on a circuit that was NOT
monitored.

I went with the remote because too amny times I would set up for a cut and
realize that I didn't start the DC and just make the cut (and mess) without
it.

My simpler solution is a remote control. I keep it next to my safety
glasses and hearing protector and clip it onto my belt when I get started
and it stays there until I'm done for the day. Then anywhere I am, if I
need it I just push the button. I have seen current sensing devices that
can be placed in the circuits that power certain tools that will switch on
the DC when they sense current draw but for a single person shop, I
personally think that is just a waste of money.

I would like to avoid the "auto start" version myself.
I have had several folks mention wiring a plug to the
"coil" but I wonder what problems that might lead to.
Since I could not identify the "coil", there is little
chance of me making "adjustments".
I want this to be "safe" and "practical"...

It's been awhile since my last electricity class but I think a current
sensing device is basically a relay set to go off when you turn on your saw
or whatever.
When I finally get tired of walking over and switching on the DC I'll
probably go with a remote, mostly because I can think of times when I'm
turning the saw off and on a lot but I want the DC to keep going.

Two different animals, I think. The tablesaw is made for that but the
bearings in the blower, especially the cheap HF DC I've got, and the motor,
are most hurt by frequent on/off cycles. That was the consensus of most
owners when I researched it. If you try to limit the number of times you
turn the DC on and off, you make it last longer. That's fine with me. When
it comes time I'll upgrade. Right now, I just try to deal with the fact
that I can't afford top o' the line for everything and try to rig it so I
can live with the extra things I have to deal with for buying the "budget"
stuff.

I don't KNOW, but think about how that mag switch works, and why it was a
good idea in the first place. I can't see it working with the remotes I
know about. That certainly doesn't preclude there being a smarter person
out there, however.
You got the bigger Delta from mine. Mine doesn't have the mag switch. I
haven't sprung for the remote yet. If I get the bigger space, then I'm
gonna get an Oneida in the deal.
Patriarch
If the mag switch works properly, I can't imagine how it would function
when the remote kills the line power to the switch. That's the whole
idea behind a mag switch--it won't route power to the equipment after a
power outage. let us know if there's a workaround remote.
My DC is hooked to a Shop Fox remote which turns itself on any time of
the day or night, every couple weeks or so. I forget to turn off the
power switch on the DC to prevent it from running when I'm not there.
I've had the remote kit replaced but the new one does the same thing.
I'm guessing the problem is in my home electrical system because motion
sensor equipped lights come on randomly, or when a light or fan is
turned off in another room. Some sort of surge in the lines. And my
backup battery unit beeps when I turn OFF my shop lights. Definitely
something marginal in the wiring.

I can understand why my bandsaw and jointer come with magnetic switches but why
does a dust collector need one? If the DC starts immediately after a power
failure... so what?

I don't think that it has much to do with the bearings and everything to do
with the size and weight of the blower impeller. The amount of effort for a
TS to get it's blade up to speed is minimal and I can't speak for every
table saw, but mine takes about a half a second or so to start up. My DC
takes about 3 to 5 seconds to come up to speed which puts a heavy load on
the motor. Remember, the impeller in a DC has many more times the mass and
a HUGE increase in air resistance over that of the typical TS blade. In my
old shop, many of my tools were on the same breaker and if I started the DC
before the tool I was going to use, no problem but if I started it after the
tool was running, about 50% of the time it would blow the breaker.
