I asume you are refering to the Super Dust Deputy
I agree about adding one - if it fits the budget. I was trying to help him stay in budget but get a DC that works and is reasonably safe. 5micron filtration is not very good and IMO requires an upgrade for safety. The SDD is more an issue of convenience, but WELL worth the money! I have one with a Wynn filter on my Delta DC, and I've had the same results as you.....clean filter, empty bag.
So roughly talking...
HF DC 160
Filter upgrade $129
$458. That's about half his budget so much more realistic than I originally thought. If he can score a planer for the other $500 he'd be good to go
Cliff it sounds like this is too late for you, but this is how I mounted my DC to the wall without help. I pulled the impeller and housing off of the motor and built a temp shelf to support the motor. This really helped, and it was easy to reinstall the housing and impeller from below.
My system is very similar to the one in your post, but I eliminated to filter by exhausting outside. I have no complaints and it works really well.
I would consider these:
and the HF dust collector with the Wynn filter.
That should keep you right around $1000 plus extra for hoses. On the jointer I would offer $425-$450 or even $400.
So I guess mounting the filter on top would have simply been too tall for his shop. I'm not a huge fan of his, but I tend to believe him when he says the setup works well. I think I'll still do what I can to mount the filter and bag on opposite sides of the chamber, as intended.
