Slowly now...
Coming together in bits and pieces. Two pictures, the shed being constructed - still have to put it together which is not actually as easy as the instructions all say. Ever tried to use self-tapping screws to drill into a flexible very thin sheet of zincalume? Sufficed to say that pilot holes make it all easier. The second picture is my home made pier in the middle of a coat of gloss black. This beauty has cost me about $100 so far.
I've had the tank 'tested' for vibration - sort of jumped up and down on it and used an accelerometer a friend had - no it wasn't my iPhone. Yes, it's a drum. It picks up vibration quite nicely and distributes it across the whole surface with surprising clarity! So, mounting the pier will require some flexible tile glue, a piece of thermally treated (exterior) rubber and some dynabolts. The glue and rubber will absorb vibration to some extent, the dynabolts hold it all in place and the pier is actually 165mm diameter, 6mm steel filled with concrete so the vibrations will be dampened significantly.
I've managed to land a 20mm piece of 256mm aluminium from a supplier in Sydney for about $35 (shipping was a bit more - but still cheaper than getting it from anywhere in Canberra!). I purchased a mini pier from ioptron for about $100 for the ieq45, again shipping was a bit more from America but it beats $500 for a plate designed from Dan's plates in America. I'm going to tap some threaded holes into the aluminium plate, mount to top part of the mini-pier (it comes off! Gives me a nice template and mounting block) directly to the aluminium plate and that way I can take it off and tap some new holes when I upgrade (or just get a new aluminium plate, not expensive).
So far, have got away with it for under $900. The wood for a floating floor will be a little expensive as I'm not going to get that second hand. I expect all up it might be about $1500 when finished.
You'll see in the picture I have some SW pipe and some black...err...other...pipe. I'm going to attach the SW pipe to the top of my inspection valve from the outflow of the water tank - water does not come up the inspection valve as it's higher than the overflow outlet. I've purchased 1kg of activated charcoal which I will hold inside the pipe with some stockings stretched over the air outlet. This will provide water cooled air into the shed. The air outlet will be a twin chimney system (yet to be fully designed by me) consisting of the black pipe, rising up from the top of one of the sides and capped (with a u-bend at the top and a mozzie-proof open air outlet). What I plan on doing is using the vacuum that the heated air in the chimney will create to draw cool air in from the air inlet (described above). It's only good for cooling down the shed when I'm not using it - as the roof will hinge off when I'm using it. But I hope that will make the whole thing a little more thermally sensible. I've got some insulshed that will line the whole thing. Best to jump in and experiment I say.
