My dust collection journey.

**Flintlock** · 22nd April 2018, 06:04 PM

Since my retirement I decided to get serious about dust extraction in my workshop.
After hours and hours of reading this and other forums, here’s my progress to date.

Here is the DE enclosure, double lined with 12mm ply and insulated.
2 hp generic DE with inlet port opened up to 150mm and reverse BMH fitted.
BMH fitted to table saw.
Before I could make the blast gates I needed to make a circle cutting jig for the router.

Sorry about the photos. Can't seem to make them right way up.

Nice work - looks like you have done your homework.

Yes I have and it is thanks to you and others here that I have been able to do this.

extractor fan 1.jpg extractor fan 2.jpgI also have 2 fans installed in the end wall. I think 1 is 550cfm but can't find anything about the Hitachi unit. Should give about 8-11 changes per hour. I will keep looking for a bigger fan to give a bit more cross ventilation.

What sort of glue did you use for the rocker gate flanges, a photo in the doc shows a squeeze bottle with ...gum glue on it?

We're all learning in one way or other. I make a lot of mistakes and things that don't work but only post some of them.

They wont be 550 CFM especially with the louvres on one fan and the grille on the other so I'd recommend getting rid of the louvres/grille. The best location for fine dust extraction by exhaust/vent fans are up high on walls which places them out of the way so they won't need any louvres and grilles for safety purposes.

RE: Bigger fan.
I wish you were closer I have an absolute beauty in my shed I cannot give away that you could have.
Its a 1HP 600 mm fan from an evap AC and it even has a semi-BMH style entry.
Even though its a radial fan it has 8 variable pitch blades and would probably deliver close to 2000 CFM
If anyone wants it, all it needs is a capacitor and I can help you fit that if you need help. There is a circuit diagram on the motor that shows how to wire it up that includes the capacitor.

If anyone loyal wants it shoot me a PM.

Looks like a nice "busy" shed. You will be well pleased to reduce the dust levels in there once you get it all up and running.

What's going on with the 4" ducting connected to the 6" rocker gate in the second photo above?
Not saying there's a problem, just curious.

I understand that 6" PVC junctions are pretty exxy in NZ so your installation show considerable commitment to the cause.

That is Gorilla glue. A polyurethane glue. seems to work well. Also used it to glue the PVC flanges to the MDF.

.

The 4" goes to the drill press. As an aside, I didn't have a 150-100 level invert so I used a slightly wonky 4' BMH reversed and glued it into a short length of 150mm joiner. this allowed me to fit the 4" pipe in between 2 fixed fittings. ie slide it into the 6" joiner then pull it back into the 4" bend. (if that makes scense)

You're not kidding there.
My first trip to the local plumbing supplier cost me $775.00 for 14 fittings.
150-100 Y $92.00
150 Y $69.00
150-88deg bend $51.00
150 screw base and cap $57.00
It is cheaper to buy from an Australian seller incl freight to NZ
