It senses when the "master" draws current and then powers up the
"slave".
I think the "vac turn on slightly before the saw" is moot. The
significant thing would be for the vac to be on when sawdust begins to
be created. I suspect that every tool is running for some length of
time (seconds) before cut begins. That being the case, the vac being
turned on simultaneously with the tool would effectively accomplish
what is needed.
Turning the vac off slightly after the saw seems like a pretty good
idea. One way of accomplishing that would be to use a "delay on break"
relay to power the vac. DAGS "delay on break". Example URL (not a
recommendation for this product for this use)

Sears has a thingie that will do it, probably not good for big machine.

How about a power strip mounted on the machine? Cheap and easy, if not
elegant. I know it's possible to build or buy a special switch that
will turn on both at the same time - try searching archives here or
maybe someone will reply with more info.
Good luck,

Thanks for the responses.
I looked at the switch that Sears has: there are three outlets - one
outlet for the vac and two for tools. My concerns with this are:
1. I want to use several, say 5 or 6, different machines that would all
be able to trigger the vac independently.
2. Sears' web page doesn't list any amperage ratings for their switch -
and I'd be willing to bet that no one working at the store would have a
clue. I'm planning to plug in a table saw, 13" planer, RAS, etc... I'm
afraid that I'd overload the switch.
3. I usually run the vac on a seperate circuit that the machine to
avoid tripping breakers.
Maybe this would be easier if I just had a switch at each machine that
would turn on the vac, and use the machine's switch to turn it on. At
least then I could turn on both the vac and the machine while standing
at the machine. Would it be possible to wire up a 5 or 6 way switch to
accomplish this?

Depending on how the unit is wired, you could wire the two plugs of the
outlet to two different breakers: One for the vacuum and one for the
other stuff.
I'm not sure how you'd go about actually figuring that out, and upon
thinking about it, I'm not sure if the NEC allows a single plug-in unit
like this to bridge two different circuits like that.
Well, since I don't know, I'm going to go ahead and post it in the
hopes that others have had a similar idea, but know why it is or is not
a good idea. :-)

since you're saving the pennies to get a full-on collector, do the
cheap solution now- wheel the shopvac around. setting up hoses for
shopvac sizes will be wasted when you get the collector, and fancy
remote sensor electrical devices will also probably not transfer well.
FYI, the harbor freight collector seems to work well for lots of
people, myself included:
<http://www.harborfreight.com/cpi/ctaf/displayitem.taf?Itemnumber=45378>
wait for it to go on sale- it's one of their "frequently discounted"
items.
Here is a simple Idea without rewireing your shop
http://www.shop.com/op/aprod-p41186453-k24-g4-~remote+control+plug-nover?sourceid=3
Just carry the remote from machine to machine.

I have one of the Sears switches. You plug the tool and the vac into the
box. It turns on the vac when the "master" tool is activated. It runs the
vac for about 5 seconds after the triggering tool is shut off.
You can trigger with multiple tools by running an outlet strip to the
"master" outlet of the switch, provided you don't overload the strip by
running multiple tools at once. I think the switch is rated for 13 amps.

If and whenever I get a chance to set up a dust collection system in my
workshop, I'm going to get one of these:

Thanks for that. Seems like a reasonable solution without being too
expensive, I think I'll give it a try.
Dan
13 amps should be good for your shop vac and scroll saw. Anything bigger,
look for a heavier switch.

Sears sells an electrical device to handle this. It has three or so
electrical outlets for tools, and one special outlet for the vacuum.
Whenever you turn on a tool it detects it and sends power to the
vacuum.
I have one at home that I never used. If you can't find it, let me
know and I'll get you a part number.

My setup doesn't switch the DC components (shop vac, dust collector
and air filtration) directly with the machines, but I have X-10 mini-
controllers next to each machine that control an X-10 appliance module
on each DC component. So, just before turning on the machine, I can
turn on whatever part of the DC system I need with the mini-
controller. (I still need to manipulate blast gates and shop vac hoses
manually.)
See http://www.smarthome.com/prodindex.asp?catid=2 or go to your local
Radio Shack and look at their "Plug 'n Power" line of controllers.

You asked:
Also, is it sufficient for dust collection to have the vac run only during
the
interval the saw is on? Might be better to have the vac turn on slightly
before the saw
& run slightly after the saw shuts down. Don't know how that would be
accomplished...
Start the saw (planer, jointer, sander), wait 5 seconds, begin cutting.
When cut complete, wait five seconds, turn off tool.
Won't that work?

Not hard...
1. plug with integral switch
2. duplex plug wired to #1 plug
3. vac and tool plugged into #2
OR
1. regular, plain-jane switch
2. duplex plug controlled by switch
3. vac and tool plugged into #2

As I understand your suggestion, you'd plug both the tool and the vac
into the power strip and control both with the switch on the power
strip. Should work as long as the total load doesn't exceed the
capacity of the strip.
However, you might encounter a problem with any tool which is equipped
with magnetic starters / safety switches - those switches that are
designed to prevent the machine from restarting in the event of power
loss. Some of my 220v machines are equipped with such a switch and I
am in the process of retrofitting all my stationary tools with such a
switch. (Reference "Woodwork" #89 Oct 2004 page 50-54. Note that there
are typographical errors in the parts list shown in that article)

I could use this too. I'd like my shop vac to come on when I power up
my miter saw. Is this Sears thing simply 3 outlets on one switch, or
does it sense when a "master" tool (the saw in my case) turns on, and
then power up an outlet (where the vac would be connected) in response?
I'm sure this could be done electronically. Also, is it sufficient
for dust collection to have the vac run only during the interval the saw
is on? Might be better to have the vac turn on slightly before the saw
& run slightly after the saw shuts down. Don't know how that would be
accomplished...
