For what tools, how big is your shop, what do you make, do you have 220v, etc.?

Unless you have a motor laying around, it would be cheaper to buy a used dust collector. I wouldn't buy anything smaller than 1-1/2 hp. Also rather you build or buy, you need a good filter.

Are you talking dust collector or air filter. The two are very different.

The tools don't make the craftsman....

I am talking about a dust collector. You have to have a filter on a dust collector. An air filter is also needed.

I'm questioning the op to what he wants to build. A dust collector is harder to source parts for and is likely cheaper to buy. An air filter is very easy to source parts for and can be built for about 20% of what you can buy one for.

The tools don't make the craftsman....

Have you visited the dust collector section here, you may get more help there.

In this day and age there is no reason to build your own when you can pick up a complete unit on sale at a rock bottom price.

Can you live with a large pile of chips below the vent, or do you need a cyclone? Have you thought about heat loss?

dust collector

By the way of introduction I did carpenter work for many years. I also drove a school bus for 30 years. Due to health problems I had to retire and get disability. I now just do my wood working. I build furniture,cabinets,stools,shelves and the like. My specialty,is crafts,toys,and models of trucks,cars.tractors,bulldozers,school buses,and the like. My shop is 20 by 24. I just recently got a 10 by 12 room that used to be attached to a mobile home. I moved it and put up against my shop. I have cabinets for patterns and a desk and shelves to store crafts on untill have a craft show. Someone asked if I had 220.I do have 220. I have a 200 amp service for my shop on a separate meter from my house. I have quite a lot of tools that I have collected over the years. I have a table saw, lathe.drill press,disk belt sander,scroll saw,band saw and a lot of small hand tools. I have a 1and1/2 hp motor off of a craftsman table saw and a furnace blower. That is why I am trying to build my own dust collector. I am on a very tight budget so I am trying to use what I have on hand. I replaced the squirrel cage with a 12 inch plywood impeller. I have it picking up some but not enough. I need to get the suction up a little more. I have it going to 55 gallon drum vented to the outside. Any advice would be much appreciated. gmcooter. By the way I got that nick name from the kids on the buss.

Is your shop heated? If your shop has 9 foot ceilings is has a volume of 4,320 cubic feet. If your dust collector moves 1000 CF a minute it will take only 4.32 minuets to completely exchange your shop air. You said you had a 1hp motor, I would get online and find the largest impeller a 1 hp motor can drive. Is your motor 3600 or 1750 rpm? 3600 rpm works best.

tip? just buy one. If money is tight, get one used, or buy one of the cheaper ones. I have a cheap one and it gets the job done (it has a 1 micron bag). Had it since 2002 and it's still going strong.

To keep breathing easy, I recently bought a Jet Air Cleaner. THAT was the smartest thing I have done for myself, for my shop activities. Now I don't get a ton of dust coating everything and needless to say, I'm breathing far cleaner air. I should have bought one back in 2002.

HF makes one that you can get for $160 at the right sale.

Just to offer a mark to beat if you plan to do it. Im not sure I could find a 1.5hp motor for that much... nevermind the blower, mounting equipment, and it has a bag.

I would simply set a pipe to swirl around a dustbin to make a cyclone. Add a filter to central exhaust
If you then buy a proper one, the lash up could be used as a pre filter. Dust removal is important as an epidemic of nasal/pharangyal? cancer showed in High Wycombe, the centre of UK woodworking. You should treat wood with almost the same care as asbestos.
