Thread: Another OZ MK2 PDRacer build in Sydney "Wood Duck"

In my attempt to produce glass-like finishes, I've taken to my usual recourse, which is to throw money at the problem; I've acquired a new toy:

1. New air-filtering machine with 5- and 1-micron filters, according to the packaging... This one acquired from Hare & Forbes/Machinery House





2. Air filter's control panel: the unit also comes with a handy remote control and mounting hardware (the stuff that can be seen lying about on top of the unit in the previous snap)


Photos on Flickr as usual...



I'm hoping tyhat it will do more than just recirculate the dust. I have also rationalised this purchase by repeatedly telling myself that it will also make the air less harmful to breathe from the dust that escapes from my other New Toys(TM). More on those anon...

Ohh, pretty.

Regardless of the finish, it will be a great quality of life improvement for the shop.

You might also think about an externally ducted exhaust fan to create a negative pressure on the shop to halt migration of airbornes into the rest of the house. It doesn't take a whole lot of power to get benefit.

Alex,

Why not build a boathouse in which to build your boats? No expense spare'd to build a $350 OZ Racer?

That will allow you to build a very tight building to keep the dust out, and the temperatures within tollerance for the epoxy, and painting.

Maybe you should have a built-in a dust capture system that connects to every tool used.

You'll be the envy of all boat builders (WELL, in fact you already are...as far as I'm concerned).

Hi David,

Funnily enough, the area had a whole lot of pairs of 4" computer fans doing just that when we moved into this house. The only problem with that was that I disconnected them all when we had the area excavated to produce "habitable rooms" (2.4 m high floor to ceiling). I've still got the power supplies, and most of the fans are still in place, all though several sets were removed when bits of wall were knocked out to create windows.

At the moment the workshop area is sealed off from the living areas above it - or supposed to be, as there are some cabling holes (made by me ;) that I haven't put the wall-plates over yet, being a lazy little cus.

I'll put the re-connection of the fans towards the top off the reconstruction list, although I am going to have to put some thought to flanging them into the stud-walling. And also mark out where to put the larger exhaust fans that I have been vaguely intending to install (I have the fans in boxes).

Thanks for the reminder :).

Cheers,
Alex.

Hi Stephen,

I would be the envy of me, too, were such a thing come to pass ;). As to the dust-capture system, I will try and get a photo or two taken of what I have in mind and post them in due course.

Cheers,
Alex.

You would be amazed at how much can get through of the really fine stuff without any noticeable holes. The pressure of opening and closing doors will pump an astounding amount of fluff at surprising velocity through places that are not even visible.

Hi Alex,
Ah yes air filters wise move that, wish I had one years ago. I lashed out recently and got a Microclene you can see it in this pic. It's centred in the shop amazing how well it works.

Now just like Abbott vs Gillard I'm going to remind you of previous statements you have made.
From your opening post in fact.

"I recently acquired a set of plans for the Mk 2 OZ PDR and the GIS from Duck Flat. To get onto the water as quickly as possible, and allow saving up for the Goat, I decided to build the Duck first."

Now get on with it boyoh.

I wondered how well those worked - I would have bought the carbon-filter one at the Sydney WWW show, except that I couldn't afford it at the time, and for some reason got side-tracked onto the Carbatec/H&F-style of unit. The Microclene is much neater and smaller .

Here's my next part of the dust-extraction solution:

1. A Hare & Forbes DC-60 1200 cfm dust collector: motor and suction side





2. Dust collector, bag side (both apparently 2-micron fabric, according to the stickers on them)





3. El cheapo H&F disc-sander: rather a lot cheaper than I was originally going to pay for - I had ordered the Woodfast sander with more features but that wasn't available any more - and its replacement wasn't going to be available for around another three months and I needed it now. This will be attached to the new dust extractor, along with the large Carbatec table saw (and maybe the Triton, eventually/optionally). Finish on the sander's casting is no great shakes - hopefully the quality of the device in operation will be better than the machine itself appears


Follow this link to my Flickr account, where these photos live online. Still no free ice-cream or lollies, though...



The disc sander will be used for future projects, including shaping of boat and aircraft parts. I do need to get a decent saw-blade cover for the Carbatec saw before I use that machine again. Too dangerous, quite apart from the dust flinging about the place.

Wow somebody had a birthday?

Alex if you can put the dusty outside and duct into the workshop. You might have to make a shelter or whatever especially for noise but having the thing outside not only keeps the noise outside but keeps any dust outside as well.

Hi Mike,

Good thinking - they are noisy brutes! I'll have a think about a shelter - there are a couple of spots that might do, but both are somewhat prone to flooding at the moment. When it rains, that is - Sydney rainfall is 100 mm below average for this time of year, according to the BoM, even though it doesn't feel like it. I suspect that part of that means the water catchment, but I didn't catch all the details. There was a particularly dry spell a whole back, and the soil is probably still soaking the stuff up. It is raining here at the moment, however.

Cheers,
Alex.

Well, I've run the air filter a few more times, and vacuumed the floor and benches during one run (after which the filter was left running for four or five hours).

A couple more passes with the white spirit, plus a couple more vacuuming sessions and repair of the painting tent (I keep treading on the walls and snapping the plastic out of the staples, clumsy oaf), and I should be ready to knock off the varnishing.

One can only hope.
