re: My latest HF dust collector upgrade (with truck filter)

Very clean setup Paul.
Much cheaper than a store bought cyclone.
I like how you sealed critical area with pipe insulation.
I am going to use the idea on some parts of my collector. I notice some very fine dust on the outside.

I hacked my JDS dust collector few years ago and added an Oneida super dust deputy, the steel version, and added a filter.

The only time I get dust in the container bellow the filter is when I let the chip bin fill up. The cone does a great job.

Looking back I could have save myself some serious money and made my own cone.
Between the 0.5 micron filter ($285 at the time) and the dust deputy (about $300), I wasted money I could have bout some lumber with…
Oh well!
