My mini tophat

[donfbecker]

I needed a small dust separator for my MPCNC, so I made a top hat out of 4" PVC pipe.  It's attached to the lid of a 2.5 gallon jar.  Seems to be working ok.  The inlet is a 1" pvc coupler.  I rough cut the radius on my band saw, and then wrapped sand paper around the 4" pvc, and sanded until I had a good tight fit.  It's attached with PVC cement, and holding well.

How are you attaching the hose to your MPCNC?

I like this idea for my drill press too.  I have a small, wall mounted vacuum there, which fills quickly.

Oh, and I should update and say this works really well, unless you are doing linear pocketing and running parallel to the grain.  When I do that, it ends up taking out long strips which clogs the baffle.  Clogs the hose though too.  If I do peel for pocketing strategy, I have no issues.

In your first post you mention using a 4" PVC pipe. Looking at the photos the pipe appears to be larger, maybe 8". Can you please confirm the correct size? Maybe you meant to say 4" radius.
