Cyclone Dust Collector -- Trash Bag Idea

As of this date, April 2017, I haven't seen anybody made a simple Cyclone Dust collector with trash bags (I looked all over the internet). I like to avoid the mess of pouring the saw dust/metal shavings into the trash or into a bag so I did this. They said the laziest people have the simpliest but effective ideas-that's me. This instructable is so simple it is mostly an idea than an instructable. And most of all it works great, at least for my purpose.

NOTE: You need to have A working Cyclone Dust collector. This instructable, is just to add plastic bag liner to an existing Cyclone Dust collector. If you have a CDC or DDC and you installed a trash bag, the vacuum will suck the bag up to the top of your collector. This is idea is only to hold the bag in place.

With this -- you dont even need to keep opening the top lid to empty the trash. The way these 5 gallons stacked almost air tight then add the thickness of the plastic bag liner makes it even better. I used it without the 3.5" bottom extension for several weeks and it worked but I like to make it more efficient. You can also easily slide it off when emptying the trash.

I took a lot of pictures so just by looking at the pictures, you can build it already without instructions.

Materials: 3 each - 5 gallon plastic tubs, (One of the tubs will just be used as the extension ring).

Tools: Jigsaw, Hot glue/gun, 50-100watt soldering gun with flat tip.

1. Removed the handle and cut the bottom of the two tubs (you can leave about 1/8" of the sides bottom for easier attachment of the extension and plastic melting joint later), stack one of the bottom less tub to the untouched tub and measure the gap inside bottom to determine how long the extented plastic you need to add (usually around 3.5").

2. Measure and cut the other bottomless tub for about 3.5" from the bottom. You need to cut it straight so it is easier to mount it later. I cut the ring on mine (amost like tall mini triangle cutout), measured it to fit in the bottom, trim, and hot glue it. then solder the joints after. (using the a flat solder tip, the melt and pull technique between the joints (like sawing) worked well for me without using any extra materials. This plastic material is so easy to work with.

It is hard to do instructions in words so you just have to look at the pictures to figure it out. So far, This is working really well for me. Don't worry too much about the plastic weld and seal. The extension is just to hold the bag to the bottom. The stacking of the tubs and the plastic liner give an airtight seal when you turn the vac on. I used a screw driver to remove the rubber seal off one of the lids and installed it with hot glue. It works just the same without it anyways but I have it so I did.
I just like to share this idea to give back to all those creative people out there that shared theirs and helped me on some of my projects.

I know it is a simple idea, but I haven't seen it done before.
