The drop box I installed to catch the big chunks before they hit my DC keeps filling up and plugging the line.
Am I missing something here – shouldn’t most of the material keep passing thru and just the large heavy stuff “drop out” ???

A picture would help. Sounds like you built a separator.

didn’t intend it to be a separator!!!
I wanted a horizontal drop out
I used an old ice chest I had because it didn’t need any further sealing = apply the Dc and the lid will not come off
I placed two 4 inch connectors on one side – because that side was relatively flat
I ASSumed the material would swirl in and back out in a 180 degree arc leaving the destructive bits in the box

I added a baffle in the middle of the ice chest as an attempt to make the material pass under the baffel and keep the box clear – that failed immediately

and in that I cannot possible remove the lid unless the DC has completely stopped – I think Ill try to “allow” some extra air into the box to promote swirl

but if anyone has another idea please help me

Kind Regards
B

There’s the major problem. The airstream may do a 180 but most of the debris will not make the curve.

Put the inlet on one end of the box and the outlet on the other end. Try it without a baffle. If it doesn’t drop enough, put a 45 degree elbow on the inside outlet connection…

I have also been dreaming that maybe some sort of “agitator” such as a piece of a snow blower on a 1 RPM motor might keep the box clear

still thinking up stuff to make this work

Thank- you
i will move the connections tonight and try again after the glue sets up
I was concerned that the big pieces would have enough momentum to pass thru the drop box if I had a straight line

Thank- you for the comment – yes I have done my homework on the thingy and thats why I am trying to build a DROP BOX

Please understand – I don’t want the drama of having to open the thingy container every two minutes to see if maybe its full or not

I simply want a drop box that doesn’t plug up with fines – yet works well enough to sort out the destructive bits before they hit the fan

Doesn’t anyone make a tested and proven device like this ? [ that doesn’t cost more than the DC did ]

I don’t understand what the difference is between a drop box and a separator?

If it does what you want to do, it will take out the largest of the objects and let the finer parts go to the dust collector.
The largest pieces are going to be larger in size, so will fill up your separator faster than whatever you have to collect the dust on the dust collector.

It seems to me you need to make something a little larger but you don’t say what size dust collector you’re using. The higher the hp and cfm, the larger your box is going to be.

You can put a window on a separator. Cut out a square in the container, heat up some thin acrylic with a heat gun, form it to the shape of the container, use some rubber material such as pond liner to make a gaskets and screw it on the container. Should look like this.

With a cyclone, any small leak in the dust bin will allow the fine dust through to the filter. I imagine the same principal would do what you want, it will also reduce air flow at the tool.

You can put a window in the catcher as Clammy says. Here’s how I did it .

That gives me an idea
I am going to place a pipe to atmosphere =opposite and inline with the suction port – of the drop box.
Ill valve it and direct it with a stub – to allow a variable “leak” that might be the Voo DOO to keep that port clear
