Dust collection

>I will be moving into a new shop in a month or so. I have a Jet 1100 dust collector that is 1100cfm. I have always run it to whatever machine is being used because I am in a temporary shop. Now I'm moving into my own shop and want to consider running a dust collection set up to each machine. I just saw a letter to the editor asking the same question and they said it wouldn't work as an overhead system, that it needed to run about 3 feet from the floor so that everything was more or less level.

Have any of you run an overhead collection system on a collector of this size? It's really going to eat up a lot of wall space if I have to run it around the shop. It also seems like I would be making longer runs thus dropping the cfm even further.

I was going to run one run along one bench to handle the various strip sanders and miter saw and the other line overhead to handle the table saw, jointer, planer and lathes. Obviously gates are needed to shut off as many branches as possible.

>John, if you can see your way clear to get a 2hp cyclone and sell the jet you will get rid of most of your dust problems. I just put in a cyclone with overhead ducts and it works very well. ck out Bill Pentz web site, it has loads in info. Good luck.

I ran mine in the ceiling and used 3" black sewer pipe and fittings. My vac is set in a room , with insulation,close to my lathe so I have a direct line to one of the vac. openings. I use the other lines for dust but the one by the lathe I use to clean the floor of shavings. I do not use the bags I just vent outside. One of the second line ports is riged as dust controll at the lathe.

Doing this makes turning cleanup a lot easier.

Good turning and be safe

A bigger dust collector as well as a bigger Air compressor and a seperate room to put them in are in the plans but probably a year or 2 away unless I win the lottery. I don't want to run a lot of ductwork only to find out it won't work. John

>Thanks Bill. I will probably try a limited run to see how it works and then add other lines later. John

>John, I have my cyclone in the same garage space(3 car garage with 2/3 shop) with over head 6inch ducts and I am so pleased with it. I made a collector for my lathe attached it with magnets and connected to cyclone with 6 in flex hose and it works great. also made a movable collector hood for my meiter saw and it sucks the saw dust like you wouldn't believe.

>John,

I have a 2hp Onedia cyclone and a 650 Jet bag unit. I use the Jet with a hose to where I am hand sanding only. On the cyclone system, I have run metal pipe to each machine, plus a floor sweep. All the pipe is run overhead. The cyclone has more than enough to pull the dust and shavings overhead. I have a dust hood similar to Raffins, and the dust is pulled into the box and on to the cyclone.

If you want to run overhead, or any runs for that matter, you need to match the pipe size as well as the length to your dust collector. You can find some online sites that will do the calculations for you. There are also some good books on dust collection that will help you in the calculations. Onedia did it for me, I sent them a layout of my machinery and they did all the pipe calculations and layout for me.

A good dust collector cannot be over stressed. I have posted here before about the sinus problems I developed in over 20 years of close hand sanding. Now I run my cyclone whenever I have run my lathe. I also don't need one of those worthless overhead units. You have to catch the dust at the source or as much as possible. The dust floating around the ceiling is not the stuff going into your lungs. You would be off putting that money towards an Airstream. If you really want/need one, there are a number of books on dust collection that show how to make one for a fraction of the store bought unit..

Oh well, I got on my soapbox again about saving your lungs - but problems caused by dust are no fun - trust me....
