    After what seems ages we have finally started installing out system. Of course this is a bad time and I feel mid January will see thing really happen. Why is this, put simply the people that are doing the system are either away or busy with other life matters. If we get the people there it should only take a few days to install.

    Everyone is keen to get it completed just need to get the ducks in line .

    So at the moment this is what we have put in place, a lot more work to happen but its a start.

    IMG_4991.jpg The PVC attached to the metal from the DE system, will be straight when we finished. IMG_4989.jpg Coming out from the system IMG_4992.jpg Reducers from 240 to 150 mm, these will run to each machine IMG_4993.jpg The support brackets, not sure if we will need to strap the pipe down or leave as is.

    Blast gates, from all accounts will be best up high, ours I dare say will be down near the machines. We are yet to make our blast gates, we will look at various options and get a start on them ASAP.

    Direct connecting our PVC lines to machines maybe possible in some cases although I feel initially there will be a minimum of flex used.

    We may enlarge our outlet to our thicknesser from 125 to 150 which will be a lot better. Will post more photos as we progress.

    A bit more action and a few more pipes are in place. Just ordered another 10 x 150 standoff brackets to support the pipe. As there are nil stocks here they should arrive mid next week. I'm hoping to put forward we have a 2 day working bee, simple to install all the piping down to the machines. If we can get a couple of days of no interruption I feel we will be very close to being complete. Maybe famous last words.

    Our 125 outlet for the thicknesser is going to be enlarged to take 150 mm suction. Going to see if there is a sheet metal fabricator that will do the adjustment, if not we will do it ourselves.

    Our blast gates are currently being made by a couple of members and these should be ready by weeks end. I would have preferred to have the gates high up however this is not going to be the case, all gates will be around machine or eye height. At this stage I do not feel will be a big issue (may regret those words).

    I have a feeling we may need to have a few gates held in the open position for when this extraction system is turned on. I will need to look at a few systems what happens at the end of the line, IE blank cap, as I seem to remember needs to have a small opening / valve. Anyway we are getting there.

    Busy time at the shed and more of the system has been installed. Starting to look the goods. One member is constructing the blast gates and a couple of others are installing the pipework. As of yesterday I think all the pipe has been installed its now the fun begins. Installing the blast gates and connecting to the machines.

    I'm trying to connect PVC direct to machines however this will not be possible with all machines and some will have a short amount of flex. Our thicknesser at this stage will be 125 although the members are happy for this to be increased in size. Once this is enlarged I should be able to attach 150 PVC direct to outlet.

    We are also moving some tools back into position which were moved to allow the scaffolding to move about. I'm hopeful once the ducting is in place the main workshop area can be put back to a more normal footprint and hand tools can be put away. Anyway things are taking shape.

    Sorry should have moved the scaffolding.

    No need to apologies for the scaffold. In fact it would have been nice to see a few shots looking down on the shop.

    Looking good!
    Nothing wrong with a short section of flex. It also helps to keep any vibrations out of the main piping system.

    A bit of a push from a few members over the last week or so and the moment of truth emerged yesterday. Our system was fired up to test to see how it would work or in fact would run.

    To be honest, I feel we all wanted to see how it would go and the work done was not in vain. After so much effort I was rather nervous to be honest, having been the main instigator and gatherer of information to design the dust extraction layout. I more than anyone wanted to work. I would like to thank everyone on here who provided input. The system is not perfect and I'm there are many improvement that can and could be made however this is a fantastic starting platform.

    The test was very basic, some might even view as barbaric, all 11 inlets were left open, these lines are all 150 mm as can be seen in previous photos. The switch was turned on and a large dust pan full of chips and dust was placed under (appox 150mm under) the last inlet and the pan of dust disappeared in a flash. All inlets tested did the same. We closed some inlets and the increased vacuum on the open inlets was impressive.

    I appreciate to achieve a true result I would need various gauges / metering tools to measure air flow as well as all machines connected.

    As for the noise from Dust Extraction system this was a bit of a surprise we were still able to talk and hear each other ok. To improve this further we will look at various ways to sound proof the DE enclosure. May have to get a meter to read decibels to get a true understanding of the noise output.

    A pity all the dust over the floor someone cut a heap of stuff up and it went everywhere. Oh well a bit of a clean up and hook the rest of the tools up hopefully may eliminate this issue in the future.

    I'd look at getting one of those free "sound pressure level" apps for you mobile. This will give you a basic idea where you are at for no cost.

    The flange is called a floor waste and can be had from plumber's suppliers.

    I used a 4" version of one of those flanges yesterday while installing a "snorkel" on my external compressor enclosure yesterday.

    I can make these flanges like I make the BMHs and they are quick and easy to make. The 6" versions cost around $7.50 so if you need lots of then then they are worth making but the 4" onesI usually cost less than $1 ($1.50 from bunnings) sp I usually just buy the 4" ones.

    The flanges I make also don't have quite as sharp a corner angle as the commercial ones and I needed a fairly sharp angled one in the above application .

    Tonto - I wish I was that clever to make the flanges. However, our local plumbing store has been really good to us and the flanges only cost $3.00 inc GST each in all $66.00, not worth engaging brain matter to make them .

    Thanks Bobl downloading a Sound Metre now.

    If all goes to plan today I aim to install the rest of the blast gates installed and connect more tools up.

    Looks like those floor flanges are unique to Oz. I don't see any in the States here. Working on the rig for BobL's 150 bell mouth maker.

    Au contraire mon ami. We have them but they aren't common. Your plan to make them is probably easier.

    Perhaps I wasn't clear. I am in the U.S. We must not use them here
    Check out Bob's process. Ain't that easy, but I plan to try it.
    Thanks, Pete.

    Sorry I was googling from here, just a touch north west of you, and found the flanges. Didn't look to see where they were located, just assumed here in North America.

    You can try speaker ports like these. More money but shape is good as an intake but not right for a blast gate.
