90 degrees - $24.19
45 degrees - $23.74
15 degrees - $44.40 all GST inclusive.

I will need one 45 degree bend at the entry to the cyclone. Until I saw the prices I was considering using 3 x 15 degree bends to even it up a bit but is it really worth the extra $109.46?

Has anyone else priced these items recently?

Hey Doug are these prices for DWV or Stormwater

AH Ha, I now see the discrepancy, you are pricing DVW fittings and pipe, you can save a lot of money by using stormwater pipe and fittings
Look here for prices
STORMWATER FITTINGS - STORMWATER JUNCTION - Pipe Online - Retic Fittings , Plumbing Fittings, Reticulation Supplies supplied Australia wide
PVC PIPE - STORMWATER PIPE - Pipe Online - Retic Fittings , Plumbing Fittings, Reticulation Supplies supplied Australia wide

Hi Capt'n

It is stormwater. The writing on the pipe identifies it as:

"WPSO150 PREMIUM BEP 150 PVC-U STORMWATER HD SC SN2-120607 23:52 3RO90 AS/NZ 1254"

some of which I can understand but most is just numbers and letters to me. I can tell that its PVC 150mm premium stormwater pipe and complies with Australian and NZ standard 1254, and I think PVC-U might mean UV resistant PVC. I suppose it doesnt really matter to us what the rest of it means but just out of curiousity does anyone know?

It's worth noting, if we can un-derail the thread for a minute, that the recess between the outside of the door, and the wall there, opposite the stairs, is 40cmx97cm. It's worth mentioning this is from the back of the wall to the axis of the door, however if I were to put the unit AWAY from the door, I might get away with it.

Hi again Mooncabbage,

Sorry, its partly my fault that the thread is off the tracks, please dont take it to heart, its endemic all over the forum and the dust extraction sub-forum is probably one of the worst, cos there are really no wrong and right answers, so comparisons start to be made and off we go on a tangent.

my opinion on your question is:

If the dusty is outside the shed the further from the door it is the better, and the worst.

The only real option you have for the intake of air into the basement is through the door. so the further the dusty is from the door the less fine dust that will be sucked back into the shed on the upside; but on the downside, the further the dusty is from the door the longer the ducting and the less efficient the dusty is just because of teh sheer volume of air tha thas to be moved through the longer ducting and the wall friction from the longer ducting.

The cost difference between a 1hp and a 2hp isnt really a lot, maybe $100 tops. Modify the 2hp inlet from 5" to 6" and run 6" ducting. Its not real hard. I just walked in from doing that project myself. Then run 6" PVC pipe to the dusty outside. Put the pipe back inside at the completion of work and close the door and have a beer.

The price jump to a 3hp unit is a big one and requires 15 amp power or 415v 3 phase, a luxury not many of us can have.

My feelings normally are "do what you can with what you can afford, a minimal effort is better than nothing", but in your case you are setting up shop in what is already a dust trap and probably already an unhealthy environment to spend much time in. You NEED good dust extraction not only to safely erradicate the dust that you create but also to improve on the existing conditions that exist in that type of environment.

Doug

Well, the carbatec 2hp dusty is $300. Originally I said I didn't want to spend a fortune, but I didnt' want to be replacing it in a hurry either. I can happily afford the economy 2hp carbadustinator ($300), IF it'll fit somewhere. Can I not run different intakes and outtakes for these things, to seperate them? Obviously you don't want the fine dust in the exhaust close to the intake.

EDIT: PS. Wasn't taking the thread derailing personally, it happens in every forum Just didn't want to interrupt you boys in the middle of your clearly important conversation

PPS. How much work is it to rearrange a dust extractor setup, so it takes up more vertical height and less floor space? For example, could I edit it such that the dust extractor itself is inside the workshop, and the bags are outside, or they are stacked in a closet, extractor at the top (or bottom) of a taller closet, with the bags above or below it.

PPPS: My main concern with having the actual dust extractor unit outside, is running power to it. I'm not a sparky, and I cbf to hire one at this stage, so I don't feel comfortable leaving a live wire on outside in all conditions. That's my OH&S training for you :P

My pipe came from Total Eden 2-3 months ago. It cost $48.36 per 6 m length. The fittings were also far cheaper than the plumbing suppliers. On average, Total Eden were about 40% cheaper than anywhere else.

Correct

There is a bit of work involved but if you would like I can give you a hand to do this
One benefit of having the whole DC outside is it gets the noise outside. For some machines like thicknessers and power saws it doesn't matter as you'll probably be wearing muffs anyway but for others like bandsaw and lathe use muffs are not usually required.

Although it will be inconvenient you can always have the DC outside and roll out an extension to it as required. It's much nicer to always have the DC plugged in so you can just turn it on.

Thanks for that, John. May be worth looking into even though the closest Total Eden is about an hour's drive from me in either direction. I already have the pipe but I haven't bought the bends and ends yet until I have got it all cut up and ready to assemble.

Doug

Hmmm. Well, I think we've established that a 2HP DC is a viable option. Now I just have to work out how to set it up. First I'm going to have to clear enough room in the basement to move though. Bulk collection starts Monday, so I gotta put some #### out on the curb asap.

Argh, the dust down there is terrible. I spent 30 minutes down there earlier sweeping and tidying, I've never coughed so much in my life. Going to have to do something about dust extraction above and beyond just the machines I think

Doug, it stands for Unplasticised PVC.

PVC-U has good resistance to chemicals, sunlight, and oxidation, although I believe there is a super-dooper UV resistant version. Plasticisers are added to make PVC flexible, as in electrical cable.

What can I say?

Doug

Hang tough, Mooncabbage.

A bloke I met in the States went through an identical process a couple of years ago. He nearly coughed up his lungs during the initial clean-up.

But now his basement is a picture. Everything is painted white, or off white, to reflect light better. His biggest problem was dust coming down from above through the old floorboards. from memory he painted the boards with a rubbery looking compound to seal the cracks before going over that in white.
