Not workin so well...

[bennybmn]

Hey guys, I could use some advice. Here's my situation...
I have the small Jet 650 DC. It's an older model, and the "funnel" was below the blower discharge. So I inverted it, and put in a baffle (see below). Recently, I emptied it, decided to check the felt upper bag. There was a TON of debri around the (now upside down) funnel and in the bag too! Looked like some planer shavings, and a lot of fine dust.  One thing I have also done is put a plastic bag IN the lower bag to make emptying easier. I think it may have been interfering with the dust settling down into the lower bag, causing scrub. So I removed the outer bag, and just have the plastic bag now.

So these are my questions....

Is the position of my baffle relative to the discharge correct?

Should I make the "gap" bigger than the 1-1/8"?

And should I add a proper upper "ring" with a smaller center hole? Rather than the upside down funnel that's in there?

Also, my shopvac/cyclon, I call it a shopclone, is working well, but the filter had a LOT of fine dust on it the other day when I went to clean it.... the diameter of the separator is 20", do you think I should make it smaller to encourage the dust to drop out more?

take a look at the pics and let me know what you think. Thanks!!


Here's the DC baffle.

I'd probably add a center ring and a tube to the DC.  Increasing from 1-1/8 to 1-3/8 or even 1-1/2 will help if the debris you're seeing is too large to fit through the current 1-1/8"

Also keep in mind that bags have nowhere near the surface area of cart. filters and almost immediately begin to look dirty.  A normal bag will develop a "cake," however.  Was your filter caked?

I think it was beyond a cake.... This felt bag I got is great, and a LOT bigger than stock, at least a foot taller if not more. In fact, I clamp it to a floor joist, the metal hook thing won't fit. That being said, it was the amount of dust and some shavings that were dropping out of the upper bag that concerned me. Tells me it was past the cake stage, ya know? So I took the bag outside and gave it a good whacking to clean it up. I think I'll do a proper ring with center tube. Good call. How big a hole should I use? 4"? I might have some 4" PVC scraps I could use...

How bout the fines in my shop vac filter? Do you think a smaller diameter separator would help with that?
