I tested the DC tonight after I got everything put back together. I can say that the old girl is back to her self once again.
So was the stove pipe mod worth it? Yes.
Did I see a huge improvement? No.
Would I do it again? Absolutely.
This mod is easy to do and the parts were easy to find. I wish I would pay closer attention to how much stuff costs but I don’t so I have no idea how much it cost me. I’d say that it was less than $30??? The efficiency gain by this mod can’t be all that much but every little bit helps.
So what now?
The next thing that must be addressed are the leaky blast gates. Every 4” gate in the shop is leaking. Not necessarily around the edges, but the gate doesn’t shut all of the way. I’ve clipped the corners to allow the dust to escape on all of the gates and sealed the edges with foil tape. Even on brand new gates, the gate just barely closes enough and once it gets a little dust in there, forget about it.
So I’m going to try my hand at making some blasts gates. I have a few ideas in my head but how hard can it be, right?
Further down the road I want to flip the blower assembly and get it on top of my barrel for a more compact arrangement. I also want to make a top hat Thien separator for my barrel. I currently have a Thien baffle that sits down inside the barrel. Because the barrel is narrower at the top and widens as it goes down, the baffle has to be smaller than the inside diameter of the barrel, or you couldn’t get the top off to empty it. This leaves a gap all the way around the baffle. I think this allows a LOT of fines through. Well a lot of fines are getting through, so I’m hoping this is the cause.
