« Part 3: So many projects I want to do, so many design descisions, so little time or money... Part 4 of Upcoming projects and designs. series Part 5: Back onto the wide drum sander... »

Okay will have parts this weekend…

I found a source for pullout 110V squirrel cage furnace fan blowers, and plan to grab one this weekend. The idea is to grab one, make sure it fits the plan from ShopNotes, or make the shop notes plan fit the blower whichever… and get to building. Some changes I want from the shop notes design.

#1. Relieve the edges with a 1/8” roundover bit. Nothing extreme, but those corners won’t be too much above my skull, I’d rather not take any chances…

#2. Sacrifice an outdoor extension cord (I have way too many anyway) to become the power cord, using a cord grommet from Ace Hardware, route the power into the cabinet.

#3. Paint. Doesn’t have to be super pretty, but I don’t want to leave it bare exposed plywood. I am considering brushing on Kilz gloss white enamel one step primer / paint. I can get a pint of the stuff cheap, and it would help keep it looking decent. I simply don’t want it looking like it was just slapped together, I want it to be, well… decent looking.

#4. Addition of electrical box, and switch / timer. Now for the question…

Does anyone know of an avaialble remote control timer / switch assembly that would fit in a standard electrical box?

I must say you people are so resourceful I would be taking the easiest route and just buy one but when I see the prices my arms suddenly become shorter than my pockets. Has any one put up a step by step with photos on how to build one of these must haves I would be interested I do have someone in mind that can help me with the technical details.

I got a special publication from August Home Publishing that covers the build called “The Complete Small Shop”. Came free with my subscription to Shop Notes Magazine. Mind you, I subscribe to several woodworking magazines, and Shop Notes, has got to be hands down my favorite. This is stuff I can actually do… (Unlike Fine Woodworking which never seems to have projects for beginning / intermediate woodworkers, just those that have alrready honed their skills…). Another good mag that has had similar projects is Wood Magazine.. I like the Shop Notes plan better…

The only thing they didn’t show me how to do, is wire the thing… I can figure that out if I am just going to use a normal switch, but I want to be able to run a timer on this thing, so I can set the timer, and walk away to let it run for a couple of hours…

Hmmm. I just thought of something stupid…

The outlet I have it on is the very same outlet the lighting is on, and is switched power. I turn the lights off, the power for this will go away…

I think I need to figure out how to put a timer on a light switch, that can be overridden, so the lights stay on until I tell them to go out, AND I can THEN set the timer to shut it down a couple of hours after I walk out…

I never hesitate to install a device on a wall, especially in the garage or shop, where I undo the light switch plate or receptacle plate, tap into the feed, run it out the side of the box, doing whatever wallboard patch is necessary, and into a timer, which I may have slightly modified from some other device, and make it surface mount or in a box.

I have done both. I did that with a salt water aquarium light….....no….call it a beacon…...one of those halogen things that could light a street lamp, and it worked great for a number of years. The timer for that one was a timer designed for automobile head bolt heaters, readily available up here, and certainly available on line. So it will usually handle 15 amps. It fit in an electrical box. So I set the box just like any other box, flush with the surface, and there was the timer on the wall. In this case, I hid it in a built in book case wall. But it would have looked fine right out in the open.

Guess the key is find a device with a timer of the right amperage, designed to fit in an electrical box, and do whatever it takes to make it work….........that I know you can do…........(-:

Look for automobile headbolt heater timers…............

The only caveat, it depends on the feeds into that light switch box. But I bet it can be done. Or, check out the feed to the lights, it may be a dedicated circuit, and you might be able to do it near the breaker box.

........hope that confuses you appropriately….........

.......and one other thing, think about running a new circuit, which might be needed anyway, into the shop. That is the approach I would take. I would surface mount the wire if necessary, and add a receptacle or two along the way….....more appropriate, and safer. If your panel is maxed out, leach from an underused circuit.

Just like when I ran 220 to my central pillar. I didn’t just put in the receptacles for the two saws, I put in two extras for future contingencies…......

..........it’s the Alaskan Duct Tape and bailing wire mentality, fused with the Alaskan ‘more firepower is better’ mentality…..(-:

The circuit was planned for this. I just sort of forgot the switched power issue… This is a 20 amp breaker / circuit that runs…

6 2 bulb 4' shop lights in the garage.
1
Single bulb screw type fixture in garage.
1 Single bulb screw type fixture in attic.
1
2 bulb 4’ recess fixture in the laundry room.
1 @ 2 bulb 4’ recess fixture in the kitchen.

Assuming as most of them I have seen, this thing is running a 5a motor, then total load on this circuit at start up is no more than 7 amps… Even if it is a 10 amp motor, I am still well within the limits of this circuit…

My suggestion of the separate circuit was to separate the light switch from the dust control, although there is certainly not much handicap in combining the two, especially with a timer.

I would like to see how your filter works out. That is something that I would consider making also. It would depend on performance (meaning filtering capability) versus cost issues. My DC does a pretty good job of keeping the fine stuff out of the air. But I really need a prefilter on it. I can see it is going to start filling up faster with increased work levels, especially routing and planing.

The air cleaner is just another stage in the dust collection / abatement setup. The dust collector does work very well for keeping dust out of the air, but without a doubt, there is stuff it misses, which is where the air cleaner comes into play…

I guess I could just leave the light on with the cleaner running when I come out of the shop. I would however, be prone to leaving it running by forgetting it is on… Which is why I want to install a timer on it. Flourescent lights on all night is no big deal, but the fan motor is going to be a big deal…

Seriously, check out the head bolt heater timers. They are mass produced and cheap, and they will handle more current than you are going to impose on it. And they are usually designed to fit in standard electrical boxes. I use a timer on my aquarium lights, orchid lights, etc. I use timers a lot, and they are mostly the same. They are reliable and replaceable, and they should be cheap, no matter the application.

And I agree with you about the dust. That’s why I am following this with interest. I can buy a Delta or other locally, but….....ah shucks…......lets be honest…......its fun to make a good performing solution that is a lot cheaper. It’s the principal of it…............(-:

What on earth is a head bolt heater? I doubt this is something I am likely to find in a tropical climate…

OK, ancient Alaskan term understood up here. Try engine block heater timer, or here is a link…...

http://store.ves1.com/Intermatic__Outdoor_Mechanical_Timer/p91712_224726.aspx

Up in the North, in the middle of the winter, when you park outside there are actually outlets to plug your car in so it will start when you are done with work. I think Intermatic has been at this forever, and into timer control of circuits for a long time. They are designed for commercial and home use. I had them in Fairbanks when I lived there. If you asked your question there…........they would mumble…..Cheechako…........

If you are still having problems, tomorrow, when I am a little better rested, I will help with the search for an economical product.

I think you would do well to order it online. Or in your region, check with swimming pool vendors. Nah, check on line…................

I paid something like $20 to buy a newfangled version of the old spring-operated attic fan timer, from Home Depot.

Goes 0 through 12hrs. It’s meant to replace a standard switch, in an old work box, so … for me … a bit of wiring will need to be done, but … easy enough.

Good luck with this!

The switch replacement timer sounds like a winner. I have seen some, and Intermatic is the name I remember seeing associated with them, that were the same sort of timer you see associated with hot tubs, saunas, or room lighting. Even seen some digital ones. There is one I am fishing for, and I just can’t place it. It is a replacement for the light switch, it has the timer, AND a switch that bypasses the timer, so say for example I just wanted to hit the lights, I just flip the switch and the circuit would get juice, but the switch in the off position would get juice by setting the timer as well… I wish I could recall where I have seen those, and who makes them, most likely Woods or Intermatic….

Here are links for the type of thing you want. The electronic has the features, but I didn’t see one in the power handling range of the spring timers…..........

Electronic – may not handle your load
http://www.rewci.com/ineltiei1how.html

Spring timer with hold – would handle the load
http://www.1000bulbs.com/Commercial-Spring-Wound-Timers/
The Intermatic FF12HHC has the hold feature you would need.

I don’t know about that 1/4 HP rating, but yeah, that is along the lines of what I am talking about, I think…

Not sure about the specs, but it looks like the GE 15806 Digital timer might do what I want it to do… I need to see if the package lists the power specs…
