Automatic switch for dust collector
Dear all,
I sent a message few days ago in order to find informations on 'automatic switch for a dust collector system'. I would like to thanks all the woodworker who gave me helpful informations. The point is that i'm looking for a shematic of such a switch in order to build my own one. As i'm working in the electronic industry, i'll be able to find the components for it if someone can send me a schematic. If anyone can help, i would be very pleased. (Perhaps i should try on an another group, an electronic one but i'm sure that some of you are very good woodworkers AND electronician ...) Thanks by advance. Didier |

I built my router table with a switched outlet in parallel with the outlet
for the router. When the switch is turned on, both outlets go live and the router turns on. A shop vac, plugged into the other outlet and left "on" comes on when the outlet goes live. You should be able to figure it out, I don't have a schematic. Steve "d2" wrote in message m...

I don't have a schematic at hand but if you're in the "electronic industry" it shouldn't be much of a challenge, I'd think.. All you need is a current-sensitive relay w/ a time-delay |

I've often thought the automatic switches for a DC system (in a home shop
anyway) were a little bit of overkill. I just have my plugged into an X2 type remote control system. I keep the remote in my shop apron and can turn it on from anywhere in the shop (as long as I have the apron on). Works for me anyway. Gary in KC "d2" wrote in message m...

I bot a remote control switch for my dust collecter at Home Depot for $15.
Much easier than building one. Remove the 'remove' in my address to e:mail me. |

I bought a remote control device sold to control Christmas lights. It
cost about $12 at Lowe's last Christmas. Works like a charm. I just clip it to my apron. Dick Durbin |

Dick Durbin Hey Dick, You and Steve need to check the current rating on those low-cost remotes. They may not be able to handle the amps required by even the smaller dust collectors. Overloading the cheaper device will most likely shorten it's life, which is tolerable because it's cheap enough to replace every year or so. But...the WORST case possibility is that it will get hot or short out and cause a fire. I had the same thought, but rejected it for this reason. The amp rating of the switch I saw was very low. This also explains why switches designed for higher powered appliances (such as the Long Ranger) cost in the $45 - 55 range. Tom |

there is a problem with such a system too. you don't want your dc turning on and
off more then a few times in a hour. baldor recommends no more then 6 times a hour. there is a lot of heat buildup starting a motor. I just use a remote to turn my system on and off. that way I can turn it off when I am done not when I shut a gate. -- Knight-Toolworks & Custom Planes Custom made wooden planes at reasonable prices See http://www.knight-toolworks.com For prices and ordering instructions. |

It's 13 amps. ================================= I think the original poster was looking for a method to either turn on his DC when he turned on his machine or to turn on the DC when he opened up a blast gate ...NOT a method to remotely turn on just the DC... I have a bad habit of say using my bandsaw and leaving the blast gate open then 10 minutes later using my tablesaw and after opening that blast gate I have two machines opened... I had at one time experimented with putting microswitches on each blast gate which allowed me to turn the DC on AND off just by opening the blast gate... There is a company who makes these BUT oh MY the price they wanted... I used Radio scacks micro switches and a 12 volt transformer from an old furnace and it worked... but when i completely redid my shop I never got around to hooking it up... For someone in the electronics indusrty it really should not be a problem to wire each blast gate up so that the DC comes on when any gate is opened ...and shuts off when all the gates are closed... I have my DC directly wired (220) and have 4 regular switches mounted in the low ceiling in my shop...no matter where I am standing in the shop I can reach one without taking more then 3 steps... beats the remote that is never in my pocket when I want it...

It is a *simple* device. consists of about 3 components: 1) a current sensor. e.g. an inductive pick-up similar to those used in 'clamp on' ammeters. 2) "something" to sense when there is sufficient current flow to indicate that a device is running. This can be as simple as a *one*transistor* 'switch'. 3) a relay to switch the DC on. needs to have a 'sensitive' coil, and high power ratings on the contacts. OR you can use two relays -- a light duty one, to switch the high-power one. The schematic is "Connect part (1) to part (2) to part (3)" If the above is "insufficiently detailed" for you, you are better off _buying_ a pre-made assembly. |

Fine Woodworking has an article from August 2005 issue on building an
automatic switch titled "Dust Detector". It can be purchased on-line from the Fine Woodworking Archive: http://www.taunton.com/store/shoppin...43066&TYPE= A Its also included in their 2004 edition of their book Small Woodworking Shops.

Digging through the pile on the shelf under the display Stanley transitional jack plane caused me to realize just what a fine magazine this is, and how many neat projects there have been over the past three years that are on my 'wannado' list. After frantically hunting under the bed, both couches, and the stack of papers-that-should-have-been-thrown-away-but-have-yet-to-make-it-to-the-r ecycle-can-that-accumulate-by-the-phone, I finally found #91 under a couple papers on my desk. Huh, that would have likely been the most likely place to look but, no, I gotta crawl around looking under dust ruffles and such... I agree wholeheartedly about the quality and appeal of Woodwork. This past fall I dropped my subscription to Fine Woodworking after 5 years. In my view it's morphed into one continuous tool or finish test after another with articles that don't go into any depth or offer variety of the woodworking world. The worst was the article on knots (of the rope variety, not wood) and how to tie loads securely. Woodwork always has at least one profile article on someone in the craft plus furniture and turning. They frequently run something on international issues and interests and a little editorial on art, design and creativity. When FWW sent my renewal bill I wrote them a note explaining why I wouldn't be reupping this year and specifically mentioned my satistaction with Woodwork as well as recommending that the editors study the first 20 years of Fine Woodworking to see how much they've changed their content and focus. -- Owen Lowe and his Fly-by-Night Copper Company ____ "Sure we'll have fascism in America, but it'll come disguised as 100% Americanism." -- Huey P.

Thank you for all your replies.
From what i can read, the subjet is not so 'obvious'. Particularly as we are working with the main line, it is not as easy as with low voltage (OK, i know the principle as described previously : current sensor, level detector, relay for switching and delay on swith off of the router, sander ,...). So if we want a design working directly on the main line voltage with few component, ... not so easy! As i'm living in Europe and that it is almost impossible to receive the WOODWORKER magazine, i would be very pleased to receive a copy (scan on .pdf, .jpg, ...) of this particular article your are talking about. I know it is not compliant with the copyright laws, but in my particular situation, i think we can do an 'exeption'! Many thanks by advance. Didier |

A few turns around the line carrying the controlling load (saw, say) to a low-voltage transister to control a switching relay...what's so hard? As simple as a 555 for delay control should suffice. |
