I’m going to be putting together a DIY dust collector this weekend. I’m going to use two 5 gallon buckets as my containment unit and have a question about the air intake/outtake. I’ve seen 2 versions. One just has the intake pipe in the top of the container with a 90. the 2nd has a straight pipe in the side and it’s cut so that if fits pretty much flush with the inner wall of the bucket. The 90 looks easier to do…but the flush cut makes me think it’ll work better. Any advice? I’d prefer to do it “right” even if it’s more work.

Hello,

I made one many years ago using two buckets, sounds like the same as you are doing.

Check out my blog Wood dust/shavings separator / Static shock – 05-20-2012 10:38 AM for some clues, mind you there is not a lot of enginnering input involved and it still works well today. beware static electricity!

The exhaust pipe from the bucket lid should go straight out the top. The air coming in should be directed to hug the sides of the bucket, where hopefully friction will slow the dust and debris down enough so that it will drop to the bottom. You can come in from the side, but it would probably be easier to have a top inlet at one edge with a 90 degree fitting attached to it inside the bucket, directing the airflow against the side. The outlet pipe should extend a couple of inches down into the bucket.

I’ve got my collector about 80% done. I used my sawzall to cut the pipe at a shallow angle and it fits almost flush with the bucket side and is held in place with a few short screws and lots of caulk. I put a piece in the top to connect the inner pipe (not exactly sure how long to make this and will experiment) and will have a short connector with an elbow on the top to connect to the shop vac. I do foresee it being a bit top heavy and will have to either weight down the bottom bucket or put it on some sort of cart/frame. When it’s only 50 in the garage the caulk takes a long time to dry…so i brought it in last night to speed up the process.

Have your say...
