Thread: SCMS Dust Extraction

Thanks Bob. I am going to have to talk to my friendly electrician to make this up I think.

For anyone that is interested - I started looking at prices for 150mm DWV fittings today.

Reece:
* around $35 for 88degree F&F elbow
* around $105 for 6M length 150mm Storm PVC
Blackwoods:
* around $17 for 88degree F&F elbow
* around $105 for 6M length 150mm Storm PVC

Big difference on the fittings !!

Cheers ...

Instead of DWV fittings look for storwater fittings as these are half the price of DWV

$105 is still expensive for 150 mm stormwater pipe. I can get it for ~$55.

Thanks Bob. The reason I went for DWV fittings was the larger bend radius - as most information I looked at showed a pretty tight radius for storm.

For some reason - your friends at pipeonline show a picture of a high radius elbow that I haven't found with someone like Vinidex.

Food for thought though !!

If you have the room then 2 x 45º will enable a longer radius of curvature 90º to be generated.
An even lower resistance is obtained by using 6 x 15º bends but this gets pretty exxy and the gains obtained get increasingly smaller by going to more an more incremental bends.

Knocked up a couple of stud walls for the DC enclosure tonight.



Reece HVAC are making me a louvred and course grilled vent 150mm x 500mm which should be ready to pick up Friday or early next week.

I'll be following your enclosure build. I'm picking up my materials tomorrow and hopefully start building in the afternoon.

What did you decide to use an external vent groeneaj ?

Using the old ventilation vent (just got to knock a brick out). I'll be running 250mm ducting through the vent and out to the man hole.

I found some ducting on ebay I just got to work out which will work best.

Frame complete. Door jamb in. Rear wall panelled, and 1 side of enclosure panelled before I ran out of light last night.



I also purchased a rubber boot that I can attach to the DC inlet with hose clamps. Seems tight, and 1 turn and its off. I can fix the duct to the wall complete with boot, then when time to empty bags on DC, loosen boot and wheel DC out of enclosure.

Looking good glen

While I understand why, it's a pity you have to take the DC out of the enclosure to empty the bags. Emptying the bags is a messy business and releases a lot of dust so if most of it can be left inside the enclosure that has to be better than in the shed. After the bags are emptied I'd suggest running the DC for about 10 minute to clear the shed air of fine dust.

Thanks bob ..

Yeah .. you are probably right about emptying in there, but I have made the enclosure reasonably neat, so my recently acquired girth and the DC may not fit in there together. No big deal to take outside the shed ... Which is possibly better anyway ... Better to let the junk escape outside ?

Taking it outside to empty the bags is definitely a good idea.

Outside cladding done, roof on, door hung .. still to fit stops and knob/lock that I had laying around.

Enclosure roof was going to be too high to llow for fittings out the top, so I decided to put in a dropped bulk head to give a little more room between roof of enclosure and garage roof.

And .. you wouldn't believe it. At Mitre 10 yesterday, I noticed some 150mm storm ... $55 per 6m length!



Still waiting for outside vent, but time to order some PVC and fittings to start the duct work.
